I would like to build a WPF window application using the following layout structure. Consider title and button on left hand frame/window like "Master Pages" in ASP.Net. On the right hand frame it should be a WPF navigation window.
When I include Navigation Window as an UI element at the last stack panel, it throws me and error. How should I design the entire layout according to the image screenshot below? Thanks
<Window x:Class="MainWindow"
xmlns:local="clr-namespace:ClientSocket"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title=" Desktop" Height="841" Width="1271" WindowStartupLocation="CenterScreen" WindowState="Maximized">
<DockPanel>
<StackPanel DockPanel.Dock ="Top" Orientation="Horizontal" Background="Red">
<TextBlock Background="red" FontSize ="36" Width="482" >
Main Title
</TextBlock>
</StackPanel>
<StackPanel Background="LightGray" DockPanel.Dock ="Left" Width="145">
<Button Content="Button1" Name="btnAndroid" Width="119" Margin="3" BorderBrush="{StaticResource {x:Static SystemColors.InfoBrushKey}}" />
<Button Content="Button2" Name="btnDownloads" Width="119" Margin="3" BorderBrush="{StaticResource {x:Static SystemColors.InfoBrushKey}}" />
<Button Content="AddNewDownloads" Height="37" Name="Button1" Width="133" />
</StackPanel>
<StackPanel>
<NavigationWindow Height="auto" Width="auto" Name="nwMain" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" BorderBrush="Blue" BorderThickness="1" />
</StackPanel>
</DockPanel>
</Window>
You cannot add a window as the child of anything, there is a nestable navigation control which you can use here instead, it is called Frame.
Layout-wise i would recommend a Grid with two rows, contains another Grid (in Grid.Row="1") with two columns.
DockPanels are sad controls that probably should not be used, unless someone points a gun at you and tells you to.

I am new to C# and WPF so please give me some ideas:
I have an WPF app used to display some stack panels,all stack panels default Visibility is set to collapsed and they will switch to visible according to the received data.
Now I want to make all these stack panels to resources so I can reuse it in some new added tab controls and stack panels.
<StackPanel x:Name="ColorOption" Visibility="Collapsed">
<TextBlock Text="Line Color" Style="{StaticResource ItemNameTextBlockStyle}"/>
<Button Style="{StaticResource ColorButtonStyle}" Click="Color_Click">
<Button.Content>
<Rectangle x:Name="LineColorRect" Style="{StaticResource ColorSelectionRectangleStyle}" />
</Button.Content>
</Button>
</StackPanel>
Above is one example of stack panels I am using. In the code behind the function "Color_Click" will change this "ColorOption" stack panel state and do something.
However after I try to put this stack panel into Windows.Resources
<Window.Resources>
<StackPanel x:Name="ColorOption" Visibility="Collapsed" x:Key="ColorOption">
<TextBlock Text="Line Color" Style="{StaticResource ItemNameTextBlockStyle}"/>
<Button Style="{StaticResource ColorButtonStyle}" Click="Color_Click">
<Button.Content>
<Rectangle x:Name="LineColorRect" Style="{StaticResource ColorSelectionRectangleStyle}" />
</Button.Content>
</Button>
</StackPanel>
</Window.Resources> (I also put the style files inside)
In the tab controls I did
<TabControl>
<TabItem Header="Tab 1" Content="{StaticResource ColorOption}"/>
</TabControl>
The visual studio shows error in the code behind says "ColorOption does not exist in the current context"
How can I fix this? Is any way to set the context? thank you
You can simply wrap the StackPanel in ContentControl and make it ControlTemplate.
<ControlTemplate x:Key="ColorOptionTemplate" TargetType="{x:Type ContentControl}">
<StackPanel x:Name="ColorOption" Visibility="Collapsed">
<TextBlock Text="Line Color" Style="{StaticResource ItemNameTextBlockStyle}"/>
<Button Style="{StaticResource ColorButtonStyle}" Click="Color_Click">
<Button.Content>
<Rectangle x:Name="LineColorRect" Style="{StaticResource ColorSelectionRectangleStyle}"/>
</Button.Content>
</Button>
</StackPanel>
</ControlTemplate>
However, you will need to change properties of controls inside the ContentControl and it would be cumbersome. So the StackPanel could be wrapped in UserControl instead.
<UserControl x:Class="WpfApp1.ColorOptionControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel x:Name="ColorOption" Visibility="Collapsed">
<TextBlock Text="Line Color" Style="{StaticResource ItemNameTextBlockStyle}"/>
<Button Style="{StaticResource ColorButtonStyle}" Click="Color_Click">
<Button.Content>
<Rectangle x:Name="LineColorRect" Style="{StaticResource ColorSelectionRectangleStyle}"/>
</Button.Content>
</Button>
</StackPanel>
</UserControl>
This is a common way in WPF. The downside is that you will need to add dependency properties to UserControl and wire up them with dependency properties of internal controls so that you can set their values at the level of UserControl and bridge them with external controls and window. This could be complicated and cumbersome as well.
So I think ideally it would be better to find an existing control which has similar functionalities you want and create a custom control deriving from the existing one.
I want to instantiate two Controls (an Expander and a Button) from two ControlTemplates. They are docked in a Dockpanel (right and left). The Expander is visible and it works fine, but the Button isn't visible.
The ControlTemplate of the Button in App.xaml:
...
<ControlTemplate x:Key="OpenFileButton" TargetType="{x:Type Button}">
<Image Name="OpenFileButton" Source="F:\AudioNodeGUI_XAML\images\filebutton.jpg">
</Image>
</ControlTemplate>
...
And the instantiation in a usercontrol:
<Grid>
<Image Source="F:\AudioNodeGUI_XAML\images\FileInputNode.jpg"/>
<DockPanel Name="dock" Width="151" Height="20" Margin="27,53,122,139">
<Expander Name="expander" Template="{StaticResource FileExpander}" Height="20" Width="41" PreviewMouseLeftButtonUp="expand" DockPanel.Dock="Left">
<ListView Name="usedFiles" Background="Black" BorderBrush="Transparent" BorderThickness="0" Width="140" Height="120" Opacity="0.5">
</ListView>
</Expander>
<Button Name="OpenFileButton" Template="{StaticResource OpenFileButton}" DockPanel.Dock="Right" />
</DockPanel>
</Grid>
But the Button isn't visible, neither in the Designer (just the outline) nor in execution. What am I doing wrong?
I suspect that your issue is just incorrect path to the image file. Unfortunately you won't have any tip about this kind of error neither in designer nor in output window. However if you have ReSharper it should highlight the path to the file if it doesn't exist
I have a Windows Forms Application that shows application Name on most application Forms as shown below. For application name 'VScodePrint 2015' I used a bitmap. To support high resolution screens I had to make a number of copies of this image to support different DPI settings.
I have just started redesigning my application using WPF to avoid having to set different images based on the DPI setting without using images.
I have created a WPF window but not sure how to render the application name like the Windows Forms version above.
Can some please show me how to render the application as per Windows Form version using XAML?
System.IO.Path.GetFileName(Assembly.GetEntryAssembly().GetName().Name);
Set a label or whatever control's content equal to that, and you will get the name as you are wanting.
I have managed to create a usercontrol that renders Window title for my windows. I am novice using WPF so may this not be the best XAML but here it is:
<UserControl x:Class="WindowTitle"
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:local="clr-namespace:WpfApplication2"
mc:Ignorable="d" Height="109.986" Width="404.929">
<RowDefinition Height="80"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Border BorderBrush="DarkGray" BorderThickness="1" CornerRadius="10,10,0,0 " Background="#FF61238B" Margin="0,0,0,1">
<StackPanel Width="Auto" Height="Auto">
<StackPanel Height="Auto" Margin="0,0,0,0" HorizontalAlignment="Center" >
<Label x:Name="lblYear" Content="2015" FontSize="12" BorderBrush="White" Foreground="White" HorizontalContentAlignment="Right" Padding="0,0,0,0" VerticalAlignment="Bottom" FontFamily="Global User Interface" Margin="0,5,0,0"/>
<Label x:Name="lblProductName" Content="VScodePrint" FontSize="48" BorderBrush="White" Foreground="White" HorizontalContentAlignment="Right" Padding="0,0,0,0" VerticalAlignment="Top" FontFamily="Global User Interface" Margin="0,-5,0,0"/>
</StackPanel>
</StackPanel>
</Border>
<Label x:Name="lblVersion" Content="Version 14.0.20 Rev 1510" Grid.Row="1" VerticalAlignment="Center" Height="37" HorizontalContentAlignment="Center" Margin="0,0,0.429,0" FontFamily="Segoe UI Semibold">
<Label.Background>
<SolidColorBrush Color="#FFDBCBE3"/>
</Label.Background>
</Label>
Below is the above Window Title usercontrol in action:
Hopefully this is a WPF issue and not a esri issue. I have an ESRI map control, and I am placing a control on top of the map. When I do this, the map no longer receives input(I can't move around or click anything). If I modify the z-index of the top control to place it behind the map, the map works fine again.
<Grid Name="MapGrid" DockPanel.Dock="Top" >
<Grid Name="MapGrid" DockPanel.Dock="Top" >
<esri:MapView x:Name="MainMapView" Panel.ZIndex="0" KeyDown="MyMapView_KeyDown" MapViewTapped="MyMapView_MapViewTapped" Map="{Binding Source={StaticResource MapResource}}" WrapAround="True" Grid.Row="0" Grid.Column="0" Initialized="MyMapView_Initialized" >
</esri:MapView>
<Expander Header="Properties" ExpandDirection="Right" Panel.ZIndex="-1">
<ItemsControl Background="Transparent" Height="700" Width="500" HorizontalAlignment="Left" VerticalAlignment="Top" Name="FeaturePropertyRegion" cal:RegionManager.RegionName="FeaturePropertyRegion" />
</Expander>
</Grid>
This code works, but if I raise the ZIndex of the Expander pannel, the map no longer receives input. I am assuming the issue has to do with the visual tree of WPF, and how input cascades down. Any ideas on what the issue could be? Thanks.
EDIT
The issue seems to be with the expander, as the map works if I remove the expander and just have the ItemsControl.
Try :
<Expander IsHitTestVisible="False">
<ItemsControl />
</Expander>
It doesn't seem to be a problem with extender, which would be very wired if it did
I tried this :
<Grid>
<Button />
<Expander HorizontalAlignment="Left" ExpandDirection="Right" VerticalAlignment="Top">
<Rectangle Fill="Red" Stretch="Fill" Width="525" Height="350"/>
</Expander>
</Grid>
I've seen quite a few people asking this question and i feel like my question is slightly different. I have a listbox that holds a series of identical custom made user controls. These controls are added to the listbox at runtime. Now i currently have my listbox items resizing themselves properly upon first creation and insertion into the control.
Here is the strange part. If I resize the listbox the controls that have been visible previously are not resized to the new listbox width. In other words if i add 12 controls and the box only shows 4 (the rest are hidden by a scrollbar) then if i resize the box the first 4 controls will still be the original width and if i scroll then the other 8 will be the correct size. Also if i manipulate the list items in any way they resize themselves to the proper width automatically. SEE EDIT2
I've tried attaching to the sizeChanged event and issuing the following on both the listbox and the items but it has had no effect. I think i need to find some way of resetting the layout information for the listbox items but i can't find the command.
item.InvalidateArrange();
item.InvalidateMeasure();
Layers.UpdateLayout();
item.UpdateLayout();
I think this has something to do with the items i'm adding because even if i detach the items from the lisbox and then attach them they remain the wrong width.
Here is my listbox code:
<ListBox x:Name="Layers" VerticalContentAlignment="Top" Margin="0,17,0,0" BorderThickness="0,1,0,0" HorizontalContentAlignment="Stretch" SizeChanged="Layers_SizeChanged">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
Here is the code for my items
<UserControl x:Class="ListOverlayItem"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Border BorderBrush="Silver" BorderThickness="0,0,0,0" Name="border1" HorizontalAlignment="Stretch">

</Grid.RowDefinitions>
<Grid.ColumnDefinitions>

<TextBlock x:Name="OverlayName" Text="{Binding Path=LocationName}" Foreground="#FFF08D2D" Margin="10,2,0,0" Grid.Column="1" FontSize="12" Height="18" VerticalAlignment="Top" />
<!-- Column 3 -->
<Button Name="SettingsButton" Grid.Column="3" Content="{Binding TRK_OV_Settings, Source={StaticResource translatorString}}" VerticalAlignment="Center" Click="SettingsButton_Click" />
<CheckBox x:Name="OverlayEnabled" FlowDirection="LeftToRight" Grid.Column="2" DataContext="{Binding}" HorizontalAlignment="Right" VerticalAlignment="Center" Grid.RowSpan="2" Checked="OverlayEnabled_Checked" Unchecked="OverlayEnabled_Unchecked" />

</Grid>
</Border>
Again it seems like my UserControl is correctly able to scale itself its just not getting the command to do so when the parent container is resized.
EDIT: Whoops, removed the WPF tag because it was incorrectly added. I think i've got it down to slider being the culprit. If i set the slider to a fixed size instead of 'stretch' then the item correctly scales just fine. So the question now is how do i force the slider to resize itself.
EDIT2: I know what is causing the issue but i don't know how to solve it. What is happening is the slider that i have in my user control will NOT resize along with the rest of the control unless i change the value of the slider during the resize. The instant i change its value even a fraction it resizes itself automatically. How can i force it to resize?
I determined that the slider was causing the issue and i tried many ways to force the slider to re-draw when it needed to but i was unsuccessful. My final solution was to remove the slider entirely. Works fine now.
