Hi I try solve how stretch user control width / height which is active in tab control to tab control width / height.
I use caliburn micro.
I create some user control. Here is it:
<UserControl x:Class="Spirit.Views.TabChatView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:Micro="clr-namespace:Caliburn.Micro;assembly=Caliburn.Micro"
xmlns:Controls="clr-namespace:Spirit.Controls" mc:Ignorable="d"
Name="ChatWindow"
Background="{StaticResource LightGrayBackground}"
Height="545" Width="680">[...]</UserControl>
This user control is active in shell, shell declaration is here.
<Window x:Class="Spirit.Views.ChatShellView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:cal="clr-namespace:Caliburn.Micro;assembly=Caliburn.Micro"
Title="ChatShellView" Height="300" Width="300">
<DockPanel>
<Button x:Name="OpenTab"
Content="Open Tab"
DockPanel.Dock="Top" />
<TabControl x:Name="Items">
<TabControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding DisplayName}" />
<Button Content="X"
cal:Message.Attach="CloseItem($dataContext)" />
</StackPanel>
</DataTemplate>
</TabControl.ItemTemplate>
</TabControl>
</DockPanel>
</Window>
Result if some user constrol is active in this shell you can see on this image:
I would like stretch user control on maximum tab control witdh / height.
Remove Height="545" Width="680" in UserControl definition

The following Combobox in WPF project needs to always have exactly two Rectangles of heights 256 and 36 in each item respectively. And when user clicks on the dropdown button of the Combobox I would like to have it display both ComboboxItems without user having to scroll.
Question: How can we achieve it? Currently it displays only first ComboboxItem (Aqua color rectangle inside), and you have to scroll to get to see the second ComboboxItem (YellowGreen color rectangle inside). I have tried setting ScrollViewer.VerticalScrollBarVisibility="Hidden" on combo box but that makes it even worst since it does not even allow to show the second item.
XANL:
<Window x:Class="Wpf_TestApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Wpf_TestApp"
mc:Ignorable="d"
Title="MainWindow" Height="569.455" Width="800">
<Grid>
<StackPanel Margin="5" Width="15">
<ComboBox DockPanel.Dock="Top" Width="25">
<DockPanel>
<ComboBoxItem DockPanel.Dock="Top">
<StackPanel Width="180" Height="260">
<Rectangle x:Name="MyRectangle" Fill="Aqua" Width="176" Height="256"/>
</StackPanel>
</ComboBoxItem>
</DockPanel>
<DockPanel>
<ComboBoxItem DockPanel.Dock="Top">
<StackPanel Width="180" Height="38">
<TextBlock Text="Second Item:" />
<Rectangle x:Name="MyOtherRectangle" Fill="YellowGreen" Width="176" Height="36"/>
</StackPanel>
</ComboBoxItem>
</DockPanel>
</ComboBox>
</StackPanel>
</Grid>
</Window>
Screenshot of the above combobox:
Display when user first clicks on dropdown of the combobox:
User has to scroll to get to the second item of the combobox:
You can use dependency property MaxDropDownHeight of ComboBox as shown below to display both combo box items in the drop down without having to scroll,
<ComboBox DockPanel.Dock="Top" Width="25" MaxDropDownHeight="Auto">
I have tested your code with 320 Height and it works perfectly fine. If you need to add more items, you can increase the MaxDropDownHeight value accordingly.
I am trying to use the extended toolkit Zoombox in my WPF Application with NET451.
I am using a tabcontrol for navigation and the items are bound to an observablecollection of ContentControls. When i change tab the content is changed but the zoomparameters are not reset. Also i want to disable zooming for certain tabitems. Binding to properties such as scale, minscale and maxscale does not seem to do the trick. My question is, how can i reset/go to home when changing view?
And how can i disable zoom for cetain tabitems?
XAML Looks like:
<Controls:MetroWindow x:Class="Metrotest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
xmlns:toolkit="http://schemas.xceed.com/wpf/xaml/toolkit"
xmlns:local="clr-namespace:Metrotest"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Controls:MetroWindow.Resources>
<BooleanToVisibilityConverter x:Key="BoolToVis" />
</Controls:MetroWindow.Resources>
<Grid>
<Grid.DataContext>
<local:MainViewModel/>
</Grid.DataContext>
<TabControl ItemsSource="{Binding tabitems}">
<TabControl.ContentTemplate>
<ItemContainerTemplate>
<Controls:FlipView
IsBannerEnabled="False"
ItemsSource="{Binding flipviewitems}" >
<Controls:FlipView.ItemTemplate>
<DataTemplate>
<toolkit:Zoombox ZoomOn="Content" x:Name="zoombox" AutoWrapContentWithViewbox="False" >
<ContentControl Content="{Binding flipview.Content}"/>
</toolkit:Zoombox>
</DataTemplate>
</Controls:FlipView.ItemTemplate>
</Controls:FlipView>
</ItemContainerTemplate>
</TabControl.ContentTemplate>
</TabControl>
</Grid>
</Controls:MetroWindow>
I have a window with a ContentControl binding:
<ContentControl Content="{Binding CurrentViewModel}" />
I also have an empty user control binds to the ContentControl:
<UserControl x:Class="UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<Grid>
</Grid>
</UserControl>
When I run and press the tab keyboard I get a dotted rectangle around the content control. How can I disable this?
I tried using Focusable="False" and FocusVisualStyle="{x:Null}" without success...
Have you tried setting IsTabStop="False", for example...
<ContentControl Height="200" Width="200" IsTabStop="False">
<ContentControl.Content>
<TextBox/>
</ContentControl.Content>
</ContentControl>
and I would suggest you combine it with this trick:
Loaded += (sender, e) =>
MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
from the answer to this question: WPF and initial focus
Override the ContentControl Style and add property FocusVisualStyle as null and implement by using style property
<ContentControl Height="200" Width="200" FocusVisualStyle="{x:Null}">
<ContentControl.Content>
<local:UserControl1/>
</ContentControl.Content>
</ContentControl>
I am new to WPF and i can not figure some things out. I just started an new project and i wanted to make a StackPanel because i saw that on a tutorial. But now i've implemented the StackPanel and i get 2 errors.
The object 'Window' already has a child and cannot add 'StackPanel'. 'Window' can accept only one child. Line 9 Position 116.
The property 'Content' is set more than once.
Can someone explain to me what i am doeing wrong.
This is my code:
<Window x:Class="CheckDatabase.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="CheckDatabase" Height="350" Width="525">
<Grid Margin="10,80,10,10" >
<TextBox TextWrapping="Wrap"/>
</Grid>
<StackPanel Grid.Column="0" Grid.Row="0" HorizontalAlignment="Left" Name="ButtonPanel" VerticalAlignment="Top">
<Button Margin="0,10,0,10">Button 1</Button>
<Button Margin="0,10,0,10">Button 2</Button>
</StackPanel>
Thanks in advance
A Window can only contain one child. However, your Window contains both a Grid and a StackPanel.
To fix this you need to put the StackPanel inside the grid (if that is the intention) or wrap both the Grid and the StackPanel inside another panel that positions the two elements in the way you want.
Some Controls like Window can only have a single child. You will have to remove the Grid or either nest another Grid arround your Grid and Stackpanel.
Example:
<Grid x:Name="outerGrid">
<Grid x:Name="innerGrid"></Grid>
<StackPanel x:Name="innerStackPanel></StackPanel>
</Grid>
Window is a ContentControl and hence can have only one Content. You can do the following to have the expected layout
<Window x:Class="CheckDatabase.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="CheckDatabase" Height="350" Width="525">
<StackPanel>
<Grid Margin="10,80,10,10" >
<TextBox TextWrapping="Wrap"/>
</Grid>
<StackPanel Grid.Column="0" Grid.Row="0" HorizontalAlignment="Left" Name="ButtonPanel" VerticalAlignment="Top">
<Button Margin="0,10,0,10">Button 1</Button>
<Button Margin="0,10,0,10">Button 2</Button>
</StackPanel>
</StackPanel>
I'm trying to build a small MVVM test application, but can't really figure how to display my user control in the MainWindow.
My Solution Explorer:
I got a resource dictionary:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:vm="clr-namespace:MVVM.ViewModel"
xmlns:vw="clr-namespace:MVVM.View">
<DataTemplate DataType="{x:Type vm:ViewModel}">
<vw:View />
</DataTemplate>
</ResourceDictionary>
I got my view:
<UserControl x:Class="MVVM.View.View"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<UserControl.Resources>
<DataTemplate x:Key="PersonTemplate">
<StackPanel>
<TextBlock Text="{Binding FirstName}" />
</StackPanel>
</DataTemplate>
</UserControl.Resources>
<ListBox ItemsSource="{Binding Path=Persons}"
ItemTemplate="{StaticResource PersonTemplate}" />
</UserControl>
and My MainWindow
<Window x:Class="MVVM.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:vm="clr-namespace:MVVM.ViewModel"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<ResourceDictionary Source="MainWindowResources.xaml" />
</Window.Resources>
<Grid>
</Grid>
</Window>
The most obvious and easiest way is to add the ContentControl element:
<Grid>
<ContentControl x:Name="mainContentControl" />
</Grid>
And after that set the Content property of this control to your view model, and the corresponding view will be loaded and applied automatically:
this.mainContentControl.Content = new ViewModel.ViewModel();
But I would prefer to use another way without datatemplates:
<Grid>
<vw:View x:Name="mainView"/>
</Grid>
this.mainView.DataContext = new ViewModel.ViewModel();
Build your VS2010 solution, then, go to your MainWindow's XAML.
On the left, there is a toolbar with button "Toolbox"
Open it, it contains all the possible WPF controls you could add to your UI
Your UserControl should appear on top of the list (in a category probably named "MVVM Controls"), just drag&drop it to your UI :)
