I am trying to fill the TextBox height for all remaining space in the DockPanel but no success. I have not even found a successful example code doing this stuff.
Here is what I have done:
<Grid x:Name="LayoutRoot">
<DockPanel Background="Red" LastChildFill="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Button DockPanel.Dock="Bottom" Content="Save" Width="100" Height="50" HorizontalAlignment="Right" Margin="10 5"/>
<TextBox AcceptsReturn="True"
AcceptsTab="True"
Margin="5 10"
TextWrapping="Wrap"/>
</DockPanel>
</Grid>
Am I missing something?? I have also tried VerticalAlignment property to Stretch of TextBox, no success. Below is the output window.
Try this,set your textbox style to NULL and check whether its working fine.
<DockPanel Background="Red" LastChildFill="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Button DockPanel.Dock="Bottom" Content="Save" Width="100" Height="50" HorizontalAlignment="Right" Margin="10 5"/>
<TextBox AcceptsReturn="True" AcceptsTab="True" Margin="5 10" TextWrapping="Wrap" Style="{x:Null}"/>
</DockPanel>
To get the textbox to autosize without having to mess with the Style you can simply set your height back to Double.NaN. The xaml below is stripped to only show the relevant bits.
<DockPanel LastChildFill="True">
<Button DockPanel.Dock="Bottom"/>
<TextBox Height="NaN"/>
</DockPanel>

Why won't my TextBox fill the available space in its DockPanel parent? I expected it to stretch to fill the remaining horizontal space. The Button is attached to the right nicely. I've got this at the top of my Window:
<DockPanel Margin="20,10,20,0" DockPanel.Dock="Top" >
<TextBox TextWrapping="Wrap" Text="{Binding Input}" Background="#FFE4EBFF" Margin="0,0,5,0" />
<Button Content=" _Evaluate" IsDefault="True" HorizontalAlignment="Right" DockPanel.Dock="Right" />
</DockPanel>
The TextBox attaches to the left but is about 5 pixels wide. It's the last child, and has the defaults DockPanel.Dock=Left, HorizontalAlignment=Stretch. I've tried other dock and alignment values without success. Is TextBox an exception to the usual layout rules?
When you set DockPanel.LastChildFill=true
What is the last child you're adding?
The button.
Not the textbox.
Order is top (first) to bottom (last).
I'm not sure exactly what result you want but maybe you just need to make the textbox the last child:
<DockPanel Margin="20,10,20,0" DockPanel.Dock="Top" >
<Button Content=" _Evaluate" IsDefault="True" HorizontalAlignment="Right" DockPanel.Dock="Right" />
<TextBox TextWrapping="Wrap" Text="{Binding Input}" Background="#FFE4EBFF" Margin="0,0,5,0" />
</DockPanel>
This seems to work for me:
<DockPanel Margin="20,10,20,0" DockPanel.Dock="Top" LastChildFill="True">
<Button Content=" _Evaluate" IsDefault="True" HorizontalAlignment="Right" DockPanel.Dock="Right" />
<TextBox TextWrapping="Wrap" Text="{Binding Input}" Background="#FFE4EBFF" Margin="0,0,5,0" />
</DockPanel>
I have this user control:
And I want to achieve this result:
The XAML of the bottom part is like this:
<StackPanel HorizontalAlignment="left" Orientation="Horizontal">
<TextBox materialDesign:HintAssist.Hint="Filtrar por patente" Width="auto" Margin="5" Text="{Binding Filtro, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" HorizontalAlignment="Left"></TextBox>
<Button Width="120" Style="{DynamicResource MaterialDesignRaisedButton}" Margin="5" HorizontalAlignment="Right" Command="{x:Static materialDesign:DialogHost.CloseDialogCommand}">Volver</Button>
</StackPanel>
I cannot find a way to align textbox to the left and button to the right, leaving a dynamic space in the middle. Button should have fixed width and textbox should be auto.
Thanks
Use a DockPanel. You'll want to stretch it instead of aligning it to the left.
<DockPanel
HorizontalAlignment="Stretch"
>
<TextBox
DockPanel.Dock="Left"
materialDesign:HintAssist.Hint="Filtrar por patente"
Width="auto"
Margin="5"
Text="{Binding Filtro, UpdateSourceTrigger=PropertyChanged}"
HorizontalAlignment="Left"
/>
<Button
DockPanel.Dock="Right"
Width="120"
Style="{DynamicResource MaterialDesignRaisedButton}"
Margin="5"
HorizontalAlignment="Right"
Command="{x:Static materialDesign:DialogHost.CloseDialogCommand}"
>Volver</Button>
</DockPanel>
I tried to implement case in which one TextBlock appears on top of another TextBlock, playing with Visibility property - but it doesn't working yet.
TextBlock are inside DockPanel:
<DockPanel Grid.Row="1" Margin="5">
<TextBlock Text="Text1" Height="20" HorizontalAlignment="Right" DockPanel.Dock="Right">
<TextBlock Text="Text2" Background="Aqua" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Visibility="{Binding IfDeviceSelected, NotifyOnSourceUpdated=True, Converter={StaticResource ResourceKey=BoolToVisibilityConverter}}" />
</TextBlock>
<TextBlock Text="#Device Focus:" Height="20" HorizontalAlignment="Right" DockPanel.Dock="Right" />
</DockPanel>
You will want to use a Grid to group these TextBlocks, DockPanel/StackPanel will not allow overlapping controls(without horrible manipulation of Margins etc)
<DockPanel Grid.Row="1" Margin="5" >
<Grid DockPanel.Dock="Right" >
<TextBlock Text="Text1" />
<TextBlock Text="Text2" Background="Aqua" Visibility="{Binding IfDeviceSelected, NotifyOnSourceUpdated=True, Converter={StaticResource ResourceKey=BoolToVisibilityConverter}}" />
</Grid>
<TextBlock Text="#Device Focus:" Height="20" HorizontalAlignment="Right" DockPanel.Dock="Right" />
</DockPanel>
This is my original code:
<StackPanel Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="2" Orientation="Horizontal">
<ProgressBar Height="23" Name="searchProgressBar" Foreground="Blue" BorderBrush="#00000000" BorderThickness="1" VerticalAlignment="Top" HorizontalAlignment="Stretch"/>
<TextBlock Text="asdf" Height="23" Name="progressTextBlock" VerticalAlignment="Top" Foreground="Red" HorizontalAlignment="Right"/>
</StackPanel>
The progressbar was very small, maybe 2 or 3 pixels wide, then there was the text block and empty space after. So I tried explicitly docking the elements to sides:
<DockPanel Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="2" >
<ProgressBar DockPanel.Dock="Left" Height="23" Name="searchProgressBar" Foreground="Blue" BorderBrush="#00000000" BorderThickness="1" VerticalAlignment="Top" />
<TextBlock DockPanel.Dock="Right" Text="asdf" Height="23" Name="progressTextBlock" VerticalAlignment="Top" Foreground="Red" HorizontalAlignment="Right"/>
</DockPanel>
No avail. I also tried modifying each solution by setting HorizontalAlignment="Stretch" on the progress bar, but there's no change. How do i stretch it to fill all the space there is after the text block has been rendered?
Remove DockPanel.Dock="Left" from the ProgressBar and switch the order of the controls:
<DockPanel>
<TextBlock DockPanel.Dock="Right" Height="23" VerticalAlignment="Top" HorizontalAlignment="Right"/>
<ProgressBar Height="23" VerticalAlignment="Top" />
</DockPanel>
By default, DockPanel has its property LastChildFill set to true, which will make the ProgressBar take the available space.
ahh I see what you're trying to do. This is probably a better place to use a grid with 2 column definitions. The first(the left one) columndefinition with Width="*" and the second(the right one) with a width set to Width="Auto". For more info about auto vs * see http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/9a7e6591-1fae-4295-b68a-be97e8e53d06/
Notice how the textbox expands to the right until it has enough horizontal space to fit the content? Well I'd like it to not expand and fit the text with the space it has in the window.
If the windows expands, then the Grid.Column it's in will expand, but the textbox itself should expand to fit. Simple enough?
Any suggestions? This is my first foray into WPF and so far it's been pretty sleek.

To get a TextBox to wrap inside a ListBox you can make the following changes:
Set the content of the listbox equal to the width of the listbox using: HorizontalContentAlignment="Stretch".
Disable the horizontal scrollbar of the listbox to prevent listbox from getting the desired size of the controls and preventing the word wrap in your textbox.
Set TextWrapping="Wrap" in the TextBox
Here is the XAML:
<ListBox Grid.Row="1" x:Name="lstGames" Background="#343434" Padding="5"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
HorizontalContentAlignment="Stretch" >
</ListBox>
<TextBox Text="{Binding Synopsis}" MinHeight="76" TextWrapping="Wrap" />
I believe you need to set the Margin property of your textbox control. In the designer, you can see little circles around each textbox (and each control when you focus them, for that matter). Click the little circle on the right side of the textbox, to make that control grow marginally with the available space in the current layout control (by clicking the circle, the margin will be added into the XAML).
I don't know if in your image you've already adjusted the window size, but with that image it appears you'll also need to set the width for your textbox.
Does this help?
