I have a simple usercontrol with a single DependencyProperty. I am unable to set bindings on this property. I don't get any exceptions but the bindings just disappear.
I cannot begin to see what is going wrong here. It's so simple.
Here's my usercontrol:
XAML:
<UserControl x:Class="Test.Controls.SimpleUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="ucThis">
<TextBox Text="{Binding Path=MyString, ElementName=ucThis}" />
</UserControl>
Code:
public partial class SimpleUserControl : UserControl
{
public SimpleUserControl()
{
InitializeComponent();
}
public string MyString
{
get { return (string)GetValue(MyStringProperty); }
set { SetValue(MyStringProperty, value); }
}
public static readonly DependencyProperty MyStringProperty =
DependencyProperty.Register("MyString", typeof(string),
typeof(SimpleUserControl), new UIPropertyMetadata("simple user control"));
}
XAML from a test app:
<StackPanel>
<testControls:SimpleUserControl MyString="{Binding Path=TestString}"
x:Name="simpleUC" />
<Label Content="From control" />
<Border Margin="5"
BorderBrush="Black"
BorderThickness="1"
Visibility="{Binding Path=MyString, ElementName=simpleUC, Converter={StaticResource nullVisConv}}">
<ContentPresenter Content="{Binding Path=MyString, ElementName=simpleUC}" />
</Border>
<TextBlock Text="Value from control is null."
Margin="5"
Visibility="{Binding Path=MyString, ElementName=simpleUC, Converter={StaticResource nullVisConv}, ConverterParameter={custom:BooleanValue Value=True}}" />
<Label Content="From binding" />
<Border Margin="5"
BorderBrush="Black"
BorderThickness="1"
Visibility="{Binding Path=TestString, Converter={StaticResource nullVisConv}}">
<ContentPresenter Content="{Binding Path=TestString}" />
</Border>
<TextBlock Text="Value from binding is null."
Margin="5"
Visibility="{Binding Path=TestString, Converter={StaticResource nullVisConv}, ConverterParameter={custom:BooleanValue Value=True}}" />
<TextBox Text="You can set focus here." />
</StackPanel>
The main window for the test app has a property named TestString, is its own DataContext and implements INotifyPropertyChanged correctly. SimpleUserControl.MyString updates as it should but the property it is bound to (TestString) does not. I have inspected this with Snoop; the binding I set on the SimplerUserControl is just not present at run time. What is happening here?
UPDATE
Okay. So if I specify Mode=TwoWay the binding works. That's great. Can anyone explain to me why it behaves this way?
Thanks.
Working as designed :). DPs default to 1-way. Personally, I would change your DependencyProperty.Register() call to make the DP default to two-way. That way you don't have to specify two-way explicitly every time you use it. You'll notice that the framework typically makes DPs two-way by default when you'd want the property to write back. Just a convienience.
Yes you need to provide TwoWay Mode for Dependency Property:
public string MyString
{
get { return (string)GetValue(MyStringProperty); }
set { SetValue(MyStringProperty, value); }
}
public static readonly DependencyProperty MyStringProperty =
DependencyProperty.Register("MyString", typeof(string),
typeof(UserControl1), new FrameworkPropertyMetadata("simple user control", FrameworkPropertyMetadataOptions.BindsTwoWayByDefault));
I have created a user control having grid and few controls inside grid. I have set Opacity to .1 of my parent grid and i want to set the descendant control's opacity to 1. Is is possible to do in XAML tree architecture ?
Here is my xaml code:
<Grid Name="busyIndicatorGrid" Visibility="Visible" Opacity=".2"
Background="DarkBlue" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<StackPanel Orientation="Vertical" Opacity="1"
Background="Transparent" HorizontalAlignment="Center" VerticalAlignment="Center">
<ProgressBar Name="progressBar" Foreground="White"
IsIndeterminate="True" MinWidth="100" Height="25" VerticalAlignment="Center"/>
<TextBlock Name="txtProgressText"
FontSize="40"
Margin="0,5,0,0"
Text="Please wait while application is being initialized."
TextAlignment="Left" TextWrapping="Wrap" />
</StackPanel>
</Grid>
Opacity is a property that will be propagated down the subtree.
If parent opacity is 0.5 and child opacity is 0.2 the parent will be drawn with 50% and child will be drawn with 20% of parent's 50%... Sort of like that just for better understanding... I hope you get me :)
Try this out and you will see:
<Grid Name="busyIndicatorGrid" Visibility="Visible" Opacity=".2">
<StackPanel Orientation="Vertical" Opacity="1" >
...
<Grid Name="busyIndicatorGrid" Visibility="Visible" Opacity=".2">
<StackPanel Orientation="Vertical" Opacity="0.5">
...
Those two will be drawn differently that means the children do no take the opacity value from its parent but instead calculate their own.
If you want to control how inner children are going to be drawn I would suggest to you to create an attached property that inherits its content down the VisualTree and when set to true it changes the opacity of its "underneathly" associated elements to 1 or to their previous old value.
Here is an example:
public static bool GetChangeOpacity(DependencyObject obj)
{
return (bool)obj.GetValue(ChangeOpacityProperty);
}
public static void SetChangeOpacity(DependencyObject obj, bool value)
{
obj.SetValue(ChangeOpacityProperty, value);
}
// Using a DependencyProperty as the backing store for ChangeOpacity. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ChangeOpacityProperty =
DependencyProperty.RegisterAttached("ChangeOpacity", typeof(bool), typeof(YourClass), new FrameworkPropertyMetadata(false, FrameworkPropertyMetadataOptions.Inherits, PropertyChangedCallback));
private static void PropertyChangedCallback(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs args)
{
FrameworkElement fe = dependencyObject as FrameworkElement;
if (fe != null && (bool)args.NewValue)
{
fe.Tag = fe.Opacity;
fe.Opacity = 1;
}
else if(fe != null && fe.Tag != null)
{
fe.Opacity = (double)fe.Tag;
}
}
Thank you guys for the valuable suggestions. But i have found way to resolve my issue by using brush for the parent grid control.
<Grid Name="busyIndicatorGrid" Visibility="Visible" Opacity=".2"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.Background>
<SolidColorBrush Color="DarkBlue" Opacity="0.2"/>
</Grid.Background>
<StackPanel Orientation="Vertical"
Background="Transparent" HorizontalAlignment="Center" VerticalAlignment="Center">
<ProgressBar Name="progressBar" Foreground="White"
IsIndeterminate="True" MinWidth="100" Height="25" VerticalAlignment="Center"/>
<TextBlock Name="txtProgressText"
FontSize="40"
Margin="0,5,0,0"
Text="Please wait while application is being initialized."
TextAlignment="Left" TextWrapping="Wrap" />
</StackPanel>
By doing so it will draw parent grid with the opacity i have defined in background property and it will have no effect on inside controls. all the controls will be drawn as usual without any opacity overriding effect which was set on parent grid.
When i set the content of the content control like below but the binding of the element inside the content get break.
i have given a content inside a property of a class and set the property as the content to the content control.
[Xmal]
<Grid>
<Button HorizontalAlignment="Center"
VerticalAlignment="Top"
Click="Button_Click_1"
Content="Click" />
<local:MyTile x:Name="mytile">
<local:MyTile.TileViewContent>
<StackPanel>
<TextBox x:Name="text"
Background="Red"
Text="MyText" />
<TextBox Text="{Binding ElementName=text, Path=Text,Mode=TwoWay}" />
</StackPanel>
</local:MyTile.TileViewContent>
</local:MyTile>
<ContentControl x:Name="contentcontrol" />
</Grid>
[C#]
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
contentcontrol.Content = mytile.TileViewContent;
}
}
public class MyTile:Control
{
public FrameworkElement TileViewContent
{
get { return (FrameworkElement)GetValue(TileViewContentProperty); }
set { SetValue(TileViewContentProperty, value); }
}
public static readonly DependencyProperty TileViewContentProperty =
DependencyProperty.RegisterAttached("TileViewContent", typeof(FrameworkElement), typeof(MyTile), new PropertyMetadata(null));
}
When i set the content the binding not working. please help
If you want to simply binding is works, not necessarily through ContentControl, use the Style for your element:
<Window.Resources>
<Style x:Key="MyTemplateForMyControl" TargetType="{x:Type local:MyTile}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:MyTile}">
<StackPanel>
<TextBox x:Name="MyTextBox" Text="MyText" Background="Red" />
<TextBox Text="{Binding ElementName=MyTextBox, Path=Text}" />
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid>
<Button HorizontalAlignment="Center" VerticalAlignment="Center" Content="Click" Click="Button_Click_1" />
<local:MyTile x:Name="MyTile" />
</Grid>
In code we are set the Style for your Control:
private void Button_Click_1(object sender, RoutedEventArgs e)
{
MyTile.Style = this.Resources["MyTemplateForMyControl"] as Style;
}
If it is necessary to use ContentControl I can recommend instead of you Control use a DataTemplate:
<Window.Resources>
<DataTemplate DataType="{x:Type local:MyDataForTemplate}">
<StackPanel>
<TextBox x:Name="MyTextBox" Text="{Binding TextBoxContent}" Background="Red" />
<TextBox Text="{Binding ElementName=MyTextBox, Path=Text}" />
</StackPanel>
</DataTemplate>
<!-- Some data -->
<local:MyDataForTemplate x:Key="MyDataForTile" TextBoxContent="MyText" />
</Window.Resources>
<Grid>
<Button HorizontalAlignment="Center" VerticalAlignment="Center" Content="Click" Click="Button_Click_1" />
<ContentControl Name="TileContentControl" />
</Grid>
There will be some data for a template:
public class MyDataForTemplate
{
string textBoxContent = "";
/// <summary>
/// Text for TextBox
/// </summary>
public string TextBoxContent
{
get
{
return textBoxContent;
}
set
{
textBoxContent = value;
}
}
}
In code we are set the data for a template:
private void Button_Click_1(object sender, RoutedEventArgs e)
{
TileContentControl.Content = this.Resources["MyDataForTile"] as MyDataForTemplate;
}
I have a usercontrol with a DependencyProperty of Answer which is attached to a TextBox.
I have queried the database and bound the answer to the usercontrol and the correct value is displayed.
The issue occurs when I edit the TextBox, the PropertyChanged event is not firing and thus preventing me from saving the correct value back to the database.
Please see below my code.
Usercontrol:
<Grid>
<StackPanel>
<TextBlock Name="txtbQuestion" TextWrapping="Wrap" Text="Question" Foreground="Black" Margin="5" Style="{DynamicResource Label}" ToolTip="{Binding RelativeSource={RelativeSource Self}, Path=Text}" ></TextBlock>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition Width="100" />
</Grid.ColumnDefinitions>
<TextBox Name="txtAnswer" Margin="5" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Hidden" >
<TextBox.Style>
<Style>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=cbMultiLine, Path=IsChecked}" Value="True">
<Setter Property="TextBox.TextWrapping" Value="Wrap" />
<Setter Property="TextBox.Height" Value="100" />
<Setter Property="TextBox.AcceptsReturn" Value="True" />
</DataTrigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
<CheckBox Name="cbMultiLine" Content="MultiLine" Margin="5" FontFamily="Georgia" Grid.Column="1" />
</Grid>
<Line Fill="Black" Margin="4" />
</StackPanel>
</Grid>
Usercontrol.cs:
public partial class ConditionQuestion : UserControl
{
public static readonly DependencyProperty AnswerProperty =
DependencyProperty.Register("Answer", typeof(string), typeof(ConditionQuestion), new UIPropertyMetadata(null, Answer_PropertyChanged));
public static readonly DependencyProperty QuestionProperty =
DependencyProperty.Register("Question", typeof(string), typeof(ConditionQuestion), new UIPropertyMetadata(null, Question_PropertyChanged));
public ConditionQuestion()
{
InitializeComponent();
}
public string Answer
{
get { return (string)GetValue(AnswerProperty); }
set { SetValue(AnswerProperty, value); }
}
public string Question
{
get { return (string)GetValue(QuestionProperty); }
set { SetValue(QuestionProperty, value); }
}
private static void Answer_PropertyChanged(DependencyObject source, DependencyPropertyChangedEventArgs e)
{
((ConditionQuestion)source).txtAnswer.Text = (string)e.NewValue;
}
private static void Question_PropertyChanged(DependencyObject source, DependencyPropertyChangedEventArgs e)
{
((ConditionQuestion)source).txtbQuestion.Text = (string)e.NewValue;
}
}
Declaring instance of Usercontrol:
<ListBox ItemContainerStyle="{StaticResource noSelect}" ItemsSource="{Binding Answer}"
Name="lbQuestions" BorderBrush="#E6E6E6" >
<ListBox.ItemTemplate>
<DataTemplate>
<my:ConditionQuestion Question="{Binding ConditionReportFormQuestions.Question}"
Answer="{Binding Answer, Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I apologize in advance, I am {relatively} new to WPF. Can anyone see where I may be going wrong with this?
I have successfully got my other usercontrols binding and updating (this code is almost an exact copy) but the answers on them are ListBox selections where-as this usercontrol is binding to a TextBox.
Thanks in advance,
Kohan.
You have not bound the text box to the answer property. What you have done is put a changed handler on your answer property and when it is changed you manually set the text boxes text property.
Your code should look something like this
<TextBlock
Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type my:ConditionQuestion}}, Path=Answer, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
this is a binding between the textbox and the property Answer on the class ConditionQuestion (the user control). Whenever the Answer property changes on the user control the text box will update and whenever you change the text in the textbox the Answer property will be updated. With this code you can remove your Answer_PropertyChanged method it is no longer neccessary. the binding takes care of it
It seems that when a WPF application starts, nothing has focus.
This is really weird. Every other framework I've used does just what you'd expect: puts initial focus on the first control in the tab order. But I've confirmed that it's WPF, not just my app -- if I create a new Window, and just put a TextBox in it, and run the app, the TextBox doesn't have focus until I click on it or press Tab. Yuck.
My actual app is more complicated than just a TextBox. I have several layers of UserControls within UserControls. One of those UserControls has Focusable="True" and KeyDown/KeyUp handlers, and I want it to have the focus as soon as my window opens. I'm still somewhat of a WPF novice, though, and I'm not having much luck figuring out how to do this.
If I start my app and press the Tab key, then focus goes to my focusable control, and it starts working the way I want. But I don't want my users to have to hit Tab before they can start using the window.
I've played around with FocusManager.FocusedElement, but I'm not sure which control to set it on (the top-level Window? the parent that contains the focusable control? the focusable control itself?) or what to set it to.
What do I need to do to get my deeply-nested control to have initial focus as soon as the window opens? Or better yet, to focus the first focusable control in the tab order?
This works, too:
<Window FocusManager.FocusedElement="{Binding ElementName=SomeElement}">
<DataGrid x:Name="SomeElement">
...
</DataGrid>
</Window>
I had the bright idea to dig through Reflector to see where the Focusable property is used, and found my way to this solution. I just need to add the following code to my Window's constructor:
Loaded += (sender, e) =>
MoveFocus(new TraversalRequest(FocusNavigationDirection.First));
This will automatically select the first control in the tab order, so it's a general solution that should be able to be dropped into any window and Just Work.
Based on the accepted answer implemented as an attached behavior:
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
namespace UI.Behaviors
{
public static class FocusBehavior
{
public static readonly DependencyProperty FocusFirstProperty =
DependencyProperty.RegisterAttached(
"FocusFirst",
typeof(bool),
typeof(FocusBehavior),
new PropertyMetadata(false, OnFocusFirstPropertyChanged));
public static bool GetFocusFirst(Control control)
{
return (bool)control.GetValue(FocusFirstProperty);
}
public static void SetFocusFirst (Control control, bool value)
{
control.SetValue(FocusFirstProperty, value);
}
static void OnFocusFirstPropertyChanged(
DependencyObject obj, DependencyPropertyChangedEventArgs args)
{
Control control = obj as Control;
if (control == null || !(args.NewValue is bool))
{
return;
}
if ((bool)args.NewValue)
{
control.Loaded += (sender, e) =>
control.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
}
}
}
}
Use it like this:
<Window xmlns:Behaviors="clr-namespace:UI.Behaviors"
Behaviors:FocusBehavior.FocusFirst="true">
I found another possible solution. Mark Smith posted a FirstFocusedElement markup extension for use with FocusManager.FocusedElement.
<UserControl x:Class="FocusTest.Page2"
xmlns:FocusTest="clr-namespace:FocusTest"
FocusManager.FocusedElement="{FocusTest:FirstFocusedElement}">
After having a 'WPF Initial Focus Nightmare' and based on some answers on stack, the following proved for me to be the best solution.
First, add your App.xaml OnStartup() the followings:
EventManager.RegisterClassHandler(typeof(Window), Window.LoadedEvent,
new RoutedEventHandler(WindowLoaded));
Then add the 'WindowLoaded' event also in App.xaml :
void WindowLoaded(object sender, RoutedEventArgs e)
{
var window = e.Source as Window;
System.Threading.Thread.Sleep(100);
window.Dispatcher.Invoke(
new Action(() =>
{
window.MoveFocus(new TraversalRequest(FocusNavigationDirection.First));
}));
}
The threading issue must be use as WPF initial focus mostly fails due to some framework race conditions.
I found the following solution best as it is used globally for the whole app.
Hope it helps...

Had same problem solved it with simple solution:
In the main window:
<Window ....
FocusManager.FocusedElement="{Binding ElementName=usercontrolelementname}"
... />
In the user control:
private void UserControl_GotFocus_1(object sender, RoutedEventArgs e)
{
targetcontrol.Focus();
this.GotFocus -= UserControl_GotFocus_1; // to set focus only once
}
You can easily have the control set itself as the focused element in XAML.
<Window>
<DataGrid FocusManager.FocusedElement="{Binding RelativeSource={RelativeSource Self}}">
...
</DataGrid>
</Window>
I've never tried setting this in a usercontrol and seeing if this works, but it may.
A minimal version of Mizipzor's answer for C# 6+.
public static class FocusBehavior
{
public static readonly DependencyProperty GiveInitialFocusProperty =
DependencyProperty.RegisterAttached(
"GiveInitialFocus",
typeof(bool),
typeof(FocusBehavior),
new PropertyMetadata(false, OnFocusFirstPropertyChanged));
public static bool GetGiveInitialFocus(Control control) => (bool)control.GetValue(GiveInitialFocusProperty);
public static void SetGiveInitialFocus(Control control, bool value) => control.SetValue(GiveInitialFocusProperty, value);
private static void OnFocusFirstPropertyChanged(DependencyObject obj, DependencyPropertyChangedEventArgs args)
{
var control = obj as Control;
if (control == null || !(args.NewValue is bool))
return;
if ((bool)args.NewValue)
control.Loaded += OnControlLoaded;
else
control.Loaded -= OnControlLoaded;
}
private static void OnControlLoaded(object sender, RoutedEventArgs e) => ((Control)sender).MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
}
Use in your XAML:
<Window local:FocusBehavior.GiveInitialFocus="True" />
Above solution was not working as expected for me, I've changed slightly the behavior proposed by Mizipzor as following:
From this part
if ((bool)args.NewValue)
{
control.Loaded += (sender, e) =>
control.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
}
To this
if ((bool)args.NewValue)
{
control.Loaded += (sender, e) => control.Focus();
}
ANd I'm not attaching this behavior to Window or UserControl, but to control I want to focus initially, e.g.:
<TextBox ui:FocusBehavior.InitialFocus="True" />
Oh, sorry for different naming I'm using InitialFocus name for the attached property.
And this is working for me, maybe it could help someone else.
If you are like me, and you are using some frameworks that, somehow, mess up with the basic focus behaviors, and make all solutions above irrelevant, you can still do this :
1 - Note the element which get the focus (whatever it is!)
2 - Add this in your code behind xxx.xaml.cs
private bool _firstLoad;
3 - Add this on the element which get the first focus :
GotFocus="Element_GotFocus"
4 - Add the Element_GotFocus method in the code behind, and specify the WPF named element who need the first focus :
private void Element_GotFocus(object sender, RoutedEventArgs e)
{
if(_firstLoad)
{
this.MyElementWithFistFocus.Focus();
_firstLoad = false;
}
}
5 - Manage the Loaded event
in XAML
Loaded="MyWindow_Loaded"
in xaml.cs
private void MyWindow_Loaded(object sender, RoutedEventArgs e)
{
_firstLoad = true;
this.Element_GotFocus(null, null);
}
Hope this will help as a last resort solution
I also faced the same problem. I had three text boxes inside canvas container and wanted the first text box to be focused when the user control opens. WPF code followed MVVM pattern. I created a separate behavior class for focusing the element and binded it to my view like this.
Canvas behavior code
public class CanvasLoadedBehavior : Behavior<Canvas>
{
private Canvas _canvas;
protected override void OnAttached()
{
base.OnAttached();
_canvas = AssociatedObject as Canvas;
if (_canvas.Name == "ReturnRefundCanvas")
{
_canvas.Loaded += _canvas_Loaded;
}
}
void _canvas_Loaded(object sender, RoutedEventArgs e)
{
FocusNavigationDirection focusDirection = FocusNavigationDirection.Next;
// MoveFocus takes a TraveralReqest as its argument.
TraversalRequest request = new TraversalRequest(focusDirection);
UIElement elementWithFocus = Keyboard.FocusedElement as UIElement;
if (elementWithFocus != null)
{
elementWithFocus.MoveFocus(request);
}
}
}
Code for view
