I have a DockPanel, containing a Label with a fixed width and a TextBox with a Min and MaxWidth. I want to align the TextBox to the left and have it stretch until its MaxWidth and have it shrink until its MinWidth (if the Window is resized for example) Like this:
Panel:
<DockPanel LastChildFill="True">
<Label Content="Fixed Width" DockPanel.Dock="Left" />
<TextBox MinWidth="80" MaxWidth="250" DockPanel.Dock="Left" HorizontalAlignment="Left" />
</DockPanel>
However this only aligns the TextBox on the left. If I leave out the HorizontalAlignment it centers.
How can I achieve something like in the screenshot?
Please note that I don't want to use a Grid, since I need to wrap the TextBox at some point below the Label (I'll do this with a Trigger changing the Dock property currently).
Have a look at this solution: https://stackoverflow.com/a/13040678/4625433
You will need to move the MinWidth="80" from the TextBox to the LeftStretchPanel.
<ScrollViewer HorizontalScrollBarVisibility="Auto">
<DockPanel LastChildFill="True" Background="Yellow">
<Label Content="Fixed Width" Background="Red" />
<local:LeftStretchPanel MinWidth="80">
<TextBox MaxWidth="250" Background="Blue" />
</local:LeftStretchPanel>
</DockPanel>
</ScrollViewer>

I have a stackpanel with a fixed width.
Within the stackpanel, I have two horizontally aligned elements: a textblock and a textbox.
Is it possible to align these two elements, such they appear side-by-side, but centered within the stackpanel?
Here is my code so far:
<StackPanel Orientation="Horizontal" Width="17cm">
<TextBlock Text="Invoice Nr:"/>
<TextBox Width="2cm" />
</StackPanel>
With StackPanel it would be difficult to achieve, but with Grid it can be done by setting HorizontalAlignment and Grid.Column on the children like below:
<Grid Width="17cm" >
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock HorizontalAlignment="Right" Text="Invoice Nr:"/>
<TextBox Grid.Column="1" HorizontalAlignment="Left" Width="2cm" />
</Grid>
You could probably put the two controls within another container, and then center that container horizontally. Something like this:
<StackPanel Orientation="Horizontal" Width="17cm">
<StackPanel HorizontalAlignment="Center">
<TextBlock Text="Invoice Nr:"/>
<TextBox Width="2cm" />
</StackPanel>
</StackPanel>
I have the following XAML which is meant to show an Image and two TextBlocks on top of eachother beside it:
<StackPanel Orientation="Horizontal" >
<Image Source="{Binding CoverArt}" Height="150" />
<StackPanel Orientation="Vertical">
<StackPanel>
<TextBlock FontSize="30" Text="{Binding Title}" TextWrapping="Wrap" />
</StackPanel>
<Grid Width="auto">
<TextBlock FontSize="22" Text="{Binding Summary}" TextWrapping="Wrap" />
</Grid>
</StackPanel>
</StackPanel>
My problem is getting the text to wrap. I've tried using a Grid and assigning the columns' width but it didn't work. Neither did setting the width values to auto. The only thing that works is hard-coding the width, but I do not want that. Thanks.
A Stackpanel will stretch to the size of its content, so it's not what I would use. Use a grid, as explained in the following posts:
TextBlock TextWrapping not wrapping inside StackPanel
Text in StackPanel doesn't wrap (wp7)
TextBlock inside stackpanel does not wrap text
A quick comparison:
Before with stackpanel
After with one grid (You might want to rearrange the elements a bit)
The code for the last segment:
<pre>
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Ellipse Fill="red" Width="150" Height="150" />
<StackPanel Grid.Column="1" Orientation="Vertical">
<StackPanel>
<TextBlock FontSize="30" Text="basdljhba dnaiks d., kasndca casn oiäc cas lkcnaso ca dxjwöbdq wkjöbdqw dkjwqb " TextWrapping="Wrap" />
</StackPanel>
<Grid Width="auto">
<TextBlock FontSize="22" Text="dewdewdewdewdewewd" TextWrapping="Wrap" />
</Grid>
</StackPanel>
</Grid>
Did you try setting the width of the columns to fractions instead? width="2*" That will give you some boundaries without a pixel set size. Some way or another you need to set a constraint for the container. If you have two columns and no size is set they will get 50% each. 2* will make give that column 2/3 of the total column with, see example below.
I have a parent container that is used to hold all of my user controls. The issue is that I use VerticalAlignment="Stretch" to stretch contents to the full height and get a vertical scroll bar the user control gets stretched too much. The vertical scrollbar appears but there is no way to scroll. I know this because the down arrow for the scroll bar isn't visible.
I have <ContentControl Content="{Binding Workspace}" /> which is where a variety of controls can be assigned. For example, here is the XAML that is not working property in regards to stretching.
<StackPanel>
<TextBlock Text="{Binding FoundCount}" FontSize="13" Foreground="#666" Margin="0 0 0 8" />
<ScrollViewer VerticalAlignment="Stretch">
<TreeView
ItemsSource="{Binding Listing}"
Grid.Row="1"
BorderThickness="0"
VirtualizingStackPanel.IsVirtualizing="True" />
</ScrollViewer>
</StackPanel>
I only want to the TreeView to stretch and display a vertical scrollbar.
Any ideas?
I suspect the height of the StackPanel is not contrained so it grows to accomodate the ScrollViewer. You can check this by putting a border on the StackPanel.
<Border>
<StackPanel>
<TextBlock Text="{Binding FoundCount}" FontSize="13" Foreground="#666" />
<ScrollViewer VerticalAlignment="Stretch">
<TreeView ItemsSource="{Binding Listing}" BorderThickness="0"
VirtualizingStackPanel.IsVirtualizing="True" />
</ScrollViewer>
</StackPanel>
</Border>
I am using Silverlight 4 with Blend 4.
I have a (horizontal) stackpanel that includes some TextBoxes and a Button. The stackpanel is set to stretch to the size that the content uses. The TextBoxes are on autosize too.
When I add text to the Textboxes, the textbox size grows and the stackpanel grows too. So far so good.
When I remove text from the textboxes, the textbox size shrinks (as excepted), but the stackpanel size doesn't.
Is there any trick to make the stackpanel change size, when the content (textboxes) getting smaller?
Thanks in advance,
Frank
Here is the XAML for the UserControl:
<Grid x:Name="LayoutRoot">
<StackPanel x:Name="StackPanelBorder" Orientation="Horizontal">
<TextBox x:Name="TextBoxCharacteristicName" TextWrapping="Wrap" Text="Tex">
</TextBox>
<TextBox x:Name="TextBoxSep" TextWrapping="Wrap" Text="=" IsReadOnly="True">
</TextBox>
<Button x:Name="ButtonRemove" Content="-" Click="ButtonAddOrRemove_Click">
</Button>
</StackPanel>
</Grid>
If you want your StackPanel to resize horizontally with the items inside of it, you will need to change the HorizontalAlignment from the default value of "Stretch" to something else.
By default, the stackpanel stretches to fill the entire space of its parent control because the HorizontalAlignment is set to stretch. This makes it difficult for it to grow and shrink in size.
You will want to set the HorizontalAlignment to "Left", "Right" or to "Center". Then the stackpanel will only be as wide as the items inside of it. But choose wisely, because the stackpanel will then dock to that position inside of its parent control.
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left">
Note: If this isn't fixing your problem, then you have a problem with the Parent Control and not your StackPanel.
MSDN website for HorizontalAlignment
You would be better off using a Grid for this. Just create a Grid with 3 auto columns and it will size to fit the content.
<Grid x:Name="LayoutRoot">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBox x:Name="TextBoxCharacteristicName" TextWrapping="Wrap" Text="Tex" Grid.Column="0"/>
<TextBox x:Name="TextBoxSep" TextWrapping="Wrap" Text="=" IsReadOnly="True" Grid.Column="1"/>
<Button x:Name="ButtonRemove" Content="-" Click="ButtonAddOrRemove_Click" Grid.Column="2"/>
</Grid>
In most cases, you are much better off using a Grid. The StackPanel is a useful control, but I often feel it is overused.
I've modified your code as below. Please check.
<Grid x:Name="LayoutRoot">
<ScrollViewer x:Name="PageScrollViewer" >
<toolkit:WrapPanel x:Name="mywrapPanel" Orientation="Vertical" Width="{Binding ActualWidth, ElementName=LayoutRoot}">
<TextBox x:Name="TextBoxCharacteristicName" TextWrapping="Wrap" Text="Tex" Width="{Binding ActualWidth, ElementName=mywrapPanel}">
</TextBox>
<TextBox x:Name="TextBoxSep" TextWrapping="Wrap" Text="=" IsReadOnly="True" Width="{Binding ActualWidth, ElementName=mywrapPanel}">
</TextBox>
<Button x:Name="ButtonRemove" Content="-" Click="ButtonAddOrRemove_Click" HorizontalAlignment="Right" Width="80" Margin="2">
</Button>
</toolkit:WrapPanel>
</ScrollViewer>
</Grid>
If you use Horizontal in Orientation of WrapPanel, you may have to use the Height property binding with ActualHeight. "toolkit" can be included in header as xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit"
Hope this helps.
you need something like:
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
Also, I don't think that have a textbox which stretches is a good idea, unless it is a requirement. You should specify the width on the textbox so it doesn't stretch.
Also, if the above solution doesn't work then you should post your xaml for letting us see the document outline.
I have a StatusBar that I'd like to house a TextBlock docked to the left and a ProgressBar filling the remaining width. In all my other experiences with the WPF ProgressBar, it will fill its given container, however in this situation it doesn't auto-size at all, it just appears as a tiny circle. Setting its height and width manually work fine, but I'd like it to scale to the remaining width of the StatusBar.
Here's my XAML for the StatusBar:
<StatusBar DockPanel.Dock="Bottom" Height="25">
<StatusBarItem DockPanel.Dock="Left">
<TextBlock x:Name="lblStatus" Margin="5,0,0,0"/>
</StatusBarItem>
<StatusBarItem>
<ProgressBar x:Name="pgbStatus" />
</StatusBarItem>
</StatusBar>
You just need one extra attribute: HorizontalContentAlignment="Stretch" on the StatusBarItem. Thus:
<StatusBar DockPanel.Dock="Bottom" Height="25">
<StatusBarItem DockPanel.Dock="Left">
<TextBlock x:Name="lblStatus" Margin="5,0,0,0"/>
</StatusBarItem>
<StatusBarItem HorizontalContentAlignment="Stretch"> <!-- Note extra attribute -->
<ProgressBar x:Name="pgbStatus" />
</StatusBarItem>
</StatusBar>
