I'm working on my first WPF application and I notice that I'm not able to edit the text values in any of my textblocks.
I can't seem to find anything wrong here that would prevent me from changing it...
<Label Content="Line Terminator" Grid.Row="0" Grid.Column="0" Margin="5"></Label>
<Border BorderThickness="1" BorderBrush="LightBlue" Grid.Row="0" Grid.Column="1" Margin="5">
<TextBlock x:Name="txtLineTerm" Focusable="True" IsManipulationEnabled="True" Padding="3"></TextBlock>
</Border>
<Label Content="Field Terminator" Grid.Row="0" Grid.Column="2" Margin="5"></Label>
<Border BorderThickness="1" BorderBrush="LightBlue" Grid.Row="0" Grid.Column="3" Margin="5">
<TextBlock x:Name="txtFieldTerm" Focusable="True" IsManipulationEnabled="True" Padding="3"></TextBlock>
</Border>
Can anyone see the problem? I feel like there's a concept that I'm missing here. Any explanation will be greatly appreciated.
TextBlock is not editable. Use TextBox instead.
you can use EditableTextBlock as shown in the link
I would like to reproduce this effect :
How can I do with xaml ?
(note that the text can be variable)
Thanks in advance for your help
You can easily achieve this with a combination of Border and Grid panels:
<Grid Width="200" Height="200" VerticalAlignment="Center" HorizontalAlignment="Center">
<Border BorderThickness="1" BorderBrush="Black" Margin="0,7,0,0">
<TextBlock Text="Lorem Ipsum..." Margin="20"/>
</Border>
<Border Background="White" Margin="10,0,10,0" HorizontalAlignment="Left" VerticalAlignment="Top">
<TextBlock Text="My Title" />
</Border>
</Grid>
I am trying to modify my simple control so that the text box does not grow as the user types in long text. I took a look at some solutions posted here at Stackoverflow that suggest using a Grid and an invisible Border and binding the Width of the text box to the ActualWidth of the Border, but I can't seem to get it to work in my setup.
Here is the xaml of my control:
<StackPanel Margin="5,0">
<WrapPanel Margin="0,0,0,5">
<TextBlock Foreground="White" Margin="0,0,2,0">TEXT</TextBlock>
<TextBlock Foreground="#FF0099CC" FontWeight="Bold">MORE TEXT</TextBlock>
</WrapPanel>
<Border Margin="2,4,0,4" BorderThickness="1" SnapsToDevicePixels="True" Background="Black"
BorderBrush="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}">
<StackPanel Orientation="Horizontal">
<Image Source="..\Resources\zoom.png" Width="13"/>
<TextBox Foreground="White" Background="Black" BorderBrush="Transparent">THIS IS SOME TEXT</TextBox>
</StackPanel>
</Border>
</StackPanel>
Any ideas? I need the zoom.png to appear "inside" of the text box so I use a horizontal stack panel and just place the image and text box side by side, both surrounded by the same border.
Is there a way for me to stop my text box from auto growing as text is typed?
Thanks.
UPDATE:
Below is the xaml I am testing with.
<Window x:Class="Desktop.Shell"

</Window>
<UserControl x:Class="Desktop.SearchTextBox"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<StackPanel Margin="5,0">
<WrapPanel Margin="0,0,0,5">
<TextBlock Foreground="White" Margin="0,0,2,0">TEXT</TextBlock>
<TextBlock Foreground="#FF0099CC" FontWeight="Bold">MORE TEXT</TextBlock>
</WrapPanel>
<Border Margin="2,4,0,4" BorderThickness="1" SnapsToDevicePixels="True" Background="Black"
BorderBrush="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}">
<Grid x:Name="grdTest">
<Image HorizontalAlignment="Left" Source="..\Resources\zoom.png" Width="13"/>
<TextBox Margin="16,0,0,0" Foreground="White" Background="Black" BorderBrush="Transparent" Width="{Binding ElementName=grdTest, Path=ActualWidth}">THIS IS SOME TEXT</TextBox>
</Grid>
</Border>
</StackPanel>
</UserControl>
I just add my user control to the Window's MainRegion.
I did some more searching and found the solution. I used the below Grid to replace the grid in my original post and now the text box keeps its original size and does not auto grow on long user input. Thanks to all who looked into this.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Image Source="..\Resources\zoom.png" Width="13"/>
<Border x:Name="b" Grid.Column="1"/>
<TextBox Width="{Binding ActualWidth, ElementName=b}" Foreground="White" Background="Black" BorderBrush="Transparent"
Grid.Column="1"
VerticalAlignment="Center"
Text="THIS IS SOME TEXT"/>
</Grid>
Try to put ScrollViewer.HorizontalScrollBarVisibility="Disabled" inside Grid.
Name the Grid as x:Name="grdTest" and try this
<Grid x:Name="grdTest">
<Image HorizontalAlignment="Left" Source="..\Resources\zoom.png" Width="13"/>
<TextBox Margin="16,0,0,0" Foreground="White" Background="Black" BorderBrush="Transparent"
Width="{Binding ElementName=grdTest, Path=ActualWidth}">THIS IS SOME TEXT</TextBox>
</Grid>
To stop the grow behavior set an explicit size to the TextBox or place it in a grid with the HorizontalAlignment set to stretch
Option 1:
<TextBox Width="60">THIS IS SOME TEXT</TextBox>
Option 2:
<TextBox HorizontalAlignment="Stretch">THIS IS SOME TEXT</TextBox>
I had a very similar issue, and it turned out that my Window property "SizeToContent" was set to "WidthAndHeight", I removed setting that property, (which then defaults to "Manual") and this fixed my similar issue.
To scale the border containing the textbox to the width of the outter stack panel, change the inner stack panel to a grid and set a left margin on the text box so it doesn't overlap with the image. Also set the image's horizontal alignment to left (if that is where you want it) or it will default to the center of the border.
<StackPanel Margin="5,0">
<WrapPanel Margin="0,0,0,5">
<TextBlock Foreground="White" Margin="0,0,2,0">TEXT</TextBlock>
<TextBlock Foreground="#FF0099CC" FontWeight="Bold">MORE TEXT</TextBlock>
</WrapPanel>
<Border Margin="2,4,0,4" BorderThickness="1" SnapsToDevicePixels="True" Background="Black"
BorderBrush="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}">
<Grid>
<Image HorizontalAlignment="Left" Source="..\Resources\zoom.png" Width="13"/>
<TextBox Margin="16,0,0,0" Foreground="White" Background="Black" BorderBrush="Transparent">THIS IS SOME TEXT</TextBox>
</Grid>
</Border>
</StackPanel>
This article shows a solution for a textbox that is displayed inside a scrollviewer's viewport (in treeview or listbox). A PART_MeasureTextBlock is used (bound to the textbox) to determine the available size and set it to the textbox.
Please have look here and tell me what you think about it:

How to put text into circle in WPF XAML template?
There are a few ways to do it, like on Centering Text on a WPF Shape
Here's an example:
<Border CornerRadius="50"
Width="60"
Height="60"
Margin="10"
Padding="0,20,0,0"
Background="Aquamarine"
BorderBrush="Black"
BorderThickness="1">
<TextBlock HorizontalAlignment="Center">Test
</TextBlock>
</Border>
I'm making my first foray into WPF - I have a simple form with a popup defined for inline help. I'm using rounded corners, and for some reason a black background is bleeding through around the corners. I don't understand which element is causing the problem.

I assume it's something blindingly obvious which I'm just not seeing. Here's the XAML I'm using:
<Window x:Class="Consent.Client.SubjectNumberEntry"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" FontSize="24"
Title="SubjectNumberEntry" WindowStyle="None" WindowState="Maximized"
xmlns:h="clr-namespace:Consent.Client" KeyDown="windowOuter_KeyDown" Background="White" Name="windowOuter" AllowsTransparency="true" Loaded="Window_Loaded">
<StackPanel Height="400" DockPanel.Dock="Top" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="10">
<StackPanel Height="60" Orientation="Horizontal" VerticalAlignment="Center">
<TextBox Name="txtSubjectNumber" Margin="10" Width="400" KeyDown="txtSubjectNumber_KeyDown" h:HelpProvider.HelpString="Enter the subject identifier, or scan their wristband">
<TextBox.ToolTip>This is a textbox</TextBox.ToolTip>
</TextBox>
<Button Name="btnEnter" Margin="10" Width="100" Click="btnEnter_Click">Enter</Button>
<Button Width="50" Name="btnHelp" Margin="10" Click="btnHelp_Click">?</Button>
<Button Width="50" Name="btnExit" Margin="10" Click="btnExit_Click">Exit</Button>
</StackPanel>
<Label Name="lblValue" Margin="10"></Label>
<Popup Placement="Bottom" HorizontalAlignment="Center" VerticalOffset="10" MouseDown="popHelp_MouseDown" PopupAnimation="Fade" Name="popHelp" PlacementTarget="{Binding ElementName=txtSubjectNumber}">
<Border Padding="10" Margin="10" BorderBrush="CornflowerBlue" BorderThickness="1" CornerRadius="10" Background="CornflowerBlue">
<TextBlock FontSize="12" Background="CornflowerBlue">This is the content of the help box.</TextBlock>
</Border>
</Popup>
</StackPanel>
</Window>
I think it is the Popup that is causing the problem. Try setting AllowsTransparency to True on the popup.
Popup.AllowsTransparency
When set to False, any transparent colors are "merged" with black.
You can also wrap the popup in a border that has rounded corners. This is useful if you can't change the AllowsTransparency of the popup.
Something like this:
<Border CornerRadius="10">
<Popup Placement="Bottom" HorizontalAlignment="Center" VerticalOffset="10" MouseDown="popHelp_MouseDown" PopupAnimation="Fade" Name="popHelp" PlacementTarget="{Binding ElementName=txtSubjectNumber}">
<Border Padding="10" Margin="10" BorderBrush="CornflowerBlue" BorderThickness="1" CornerRadius="10" Background="CornflowerBlue">
<TextBlock FontSize="12" Background="CornflowerBlue">This is the content of the help box.</TextBlock>
</Border>
</Popup>
</Border>
