I have a grid that hosts a stackpanel that hosts a listbox. The Listbox once filled from the itemssource is stretching out of the visible area of the stackpanel. I have tried limiting the grid and stackpanel in size and the listbox continues to stretch out of the visible range (it just goes to edge and continues as if nothing was there to stop it instead of limiting it's size and bringing up a vertical scrollbar). The only thing that seems to help is setting the MaxHeight on the listbox, the issue is I can't tell what that height should be for different clients. I have tried different VerticalAlignments and I have the bottom margin set to 5 to try and get it to stop at the edge but nothing has had an effect yet.
Snip: Edit to add full hierarchy:
<UserControl>
<Grid x:Name="LayoutRoot" Background="White" Margin="0,0,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="230"/>
<ColumnDefinition d:DesignWidth="500"/>
<ColumnDefinition MinWidth="300" />
</Grid.ColumnDefinitions>
<StackPanel x:Name="ContentHolder" Grid.Column="0" DataContext="{Binding}" VerticalAlignment="Top">
<ListBox Name="lst" ItemsSource="{Binding}" Margin="5,0,15,5" VerticalAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Name}" />
<TextBlock Text="{Binding Number}" Margin="15,0,0,0" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</grid>
</usercontrol>
I have removed most of the names and such from the code to just use this as an example.
Answering this for anyone confused and looking for an answer in the future. Basically stackpanels step to a vertical orientation do not limit the size of their child controls vertically so anything with a scroll bar (datagrid, listbox, etc) probably shouldn't be used with them.

I have a listbox that changes size based on the size of the window. For each item in the listbox, it contains (via DataTemplate):
<Grid Height="20" HorizontalAlignment="Stretch">
<ProgressBar HorizontalAlignment="Stretch" Height="20" Value="{Binding Path=Progress, Mode=OneWay}" />
<TextBlock Margin="7,0,0,0" Text="{Binding Path=OperationTitle}" />
</Grid>
The progress bars are supposed to expand to the size of the listbox, which they do unless the text in the textblock is longer than the listbox. In that case, the textblock and the progressbar become wider than the listbox and a horizontal scroll bar appears at the bottom of the list box.
I want the progressbar and textblock to be as wide as the listbox allows and the text in the textblock to be cut off if it's longer than the listbox.
At the moment, the progress bar width is controlled by its container in one case, and its contents in another. I want it to always be controller by its container.
Thanks!
Hi if i didnt misinterpreted your question try this
<Grid Height="20" HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto" MaxWidth="100"/>
</Grid.ColumnDefinitions>
<ProgressBar HorizontalAlignment="Stretch" Height="20" Value="{Binding Path=Progress, Mode=OneWay}" Grid.Column="0" />
<TextBlock Margin="7,0,0,0" Text="OperationTitle" Grid.Column="1" />
</Grid>
I hope this will help and dont forget to set maxWidth of second column of the Grid accordingly.
try to add next property to listbox
HorizontalContentAlignment="Stretch"
I'm bulding a small WPF app over here. It's all built strictly with MVVM, using nothing but DataTemplates linked to view model types.
I've seen alot of questions about how to stretch and clip the contents of ListBoxes so that the items fill its parent. After alot of experimenting I managed to get my head around that but now I find myself in the same scenario with the ItemsControl but the same tricks doesn't seem to work.
Here's one of the DataTemplates in use (a simple TextBox). Note how I tried setting the HorizontalAlignment ...
<DataTemplate DataType="{x:Type vm:OneOfMyViewModelTypes}">
<TextBox
Text="{Binding Path=Value}"
HorizontalAlignment="Stretch"
/>
</DataTemplate>
Here's the ItemsControl inside a Grid ...
<Grid Background="Gray">
<Grid.Margin>
<Thickness
Left="{StaticResource ConfigurationDefaultMargin}"
Right="{StaticResource ConfigurationDefaultMargin}"
Bottom="{StaticResource ConfigurationDefaultMargin}"
Top="{StaticResource ConfigurationDefaultMargin}"
/>
</Grid.Margin>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="_key" Width="Auto"/>
<ColumnDefinition SharedSizeGroup="_value" Width="*"/>
</Grid.ColumnDefinitions>
<ItemsControl
Background="DimGray"
Grid.IsSharedSizeScope="True"
ItemsSource="{Binding Path=Configuration, Mode=OneWay}"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch"
>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="_key"/>
<ColumnDefinition SharedSizeGroup="_value"/>
</Grid.ColumnDefinitions>
<TextBlock
Style="{StaticResource ExtensionConfigurationLabel}"
Grid.Column="0"
Margin="5,5,5,0"
Text="{Binding Path=Caption}"
/>
<ContentPresenter
Grid.Column="1"
HorizontalAlignment="Stretch"
Margin="5,5,5,0"
Content="{Binding}"
/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
I've used colors to see how the controls sizes. The Grid is gray and the ItemsControl is dark gray.
This is the result ...
As you can see from the colors the containing Grid stretches while the ItemsControl does not. I did set its HorizontalAlignment property to Stretch but it seems it has no effect. Is there anything else I need do?
Thanks
You have two columns in your main (outer) grid, yet you use only the first column.
The second column uses all the remaining space.
Just fyi, I am new to WPF.
I am creating a sidebar in my WPF app and want rounded corners. Which I learned is not a property you can attach to a Grid. Also, I tried putting the textblocks in the border control, but the error message I got back said, "Child can only be set once".
Below is the code I have so far, but I don't like having to nest my textblocks in a stackpanel, that is nested in a grid, that is nested in a border, that is nested in the parent Grid. Any way to clean this up? (if not, no worries, again, kind of new to this, and just looking to get my xaml as organized as possible)
<Grid Style="{StaticResource SideBar}">
<Border Style="{StaticResource RoundedSidebar}">
<Grid>
<StackPanel Orientation="Vertical" VerticalAlignment="Top">
<TextBlock />
<TextBlock />
<TextBlock />
</StackPanel>
</Grid>
</Border>
</Grid>
Any feedback would be greatly appreciated.
Thanks
If you don't have any elements other than the border in that outter Grid element, you can remove that for starters.
Also, the way you have your border now, with that StackPanel being the only element of the Grid inside the border, you can remove that Grid as well...
Finally, you don't need the Orientation property set because Vertical is the default and it is perfectly normal to stack TextBlocks and other elements within a StackPanel, it is its purpose after all...
There is not much to clean up. Here is what I would do:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<Border Style="{StaticResource RoundedSidebar}" Grid.Column="1">
<StackPanel Orientation="Vertical" VerticalAlignment="Top">
<TextBlock />
<TextBlock />
<TextBlock />
</StackPanel>
</Border>
</Grid>
There are several questions related to ScrollViewer that I've researched, but none of them have worked for me. This almost certainly comes down to my lack of understanding regarding the size of an element. First, my XAML (other than the UserControl definition, this is the entire control):
<DockPanel Width="Auto">
<ScrollViewer DockPanel.Dock="Top" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Visible" CanContentScroll="True" BorderBrush="{DynamicResource PanelBorder}" BorderThickness="1,1,1,1" Background="{DynamicResource LightGradientBackgroundBrush}">
<ItemsControl Focusable="false" Width="Auto" MinHeight="30" ItemsSource="{Binding RequiredFields}" OverridesDefaultStyle="False">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<DockPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Margin="3,0,3,3">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="110"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Content="{Binding Path=Header, Mode=OneTime}" Foreground="{DynamicResource SilverBorderColorBrush}" Grid.Column="0"/>
<TextBox Text="{Binding Path=Value}" HorizontalAlignment="Stretch" Foreground="{DynamicResource SilverBorderColorBrush}" Grid.Column="1"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ScrollViewer>
</DockPanel>
This control is loaded within a tab as the content. The window that hosts the tab is resizable, and the tab content minimum size is 60. What I'm attempting to do is have the scrollviewer fill the tab, but not push the tab past the bounds of the window. With the above XAML, excess content results in the tab height expanding, and a scrollbar appearing on the Window, not the Tab.
The scrollviewer is expanding to the size of its children, therefore pushing the tab height out. What I want, is the scrollviewer to be fixed to the size of the tab, and have the content within the scrollviewer grow within the bounds of the scrollviewer, so that a scrollbar is presented when there is too much content.
Where am I going wrong?
Edit:
The problem is the Height, not the Width. The width is behaving as it should. I've changed the wrapper to a grid as suggested, but unless I set the Height property, the grid expands to fit the contents of the expanded scrollviewer, causing the same issue as before.
Updated XAML:
<Grid MinHeight="60" VerticalAlignment="Top">
<Border BorderBrush="{DynamicResource PanelBorder}" BorderThickness="1,1,1,1">
<ScrollViewer
HorizontalScrollBarVisibility="Auto"
VerticalScrollBarVisibility="Visible"
CanContentScroll="True"
BorderBrush="{DynamicResource PanelBorder}"
BorderThickness="1,1,1,1"
Background="{DynamicResource LightGradientBackgroundBrush}"
>
<ItemsControl Focusable="false" Width="Auto" MinHeight="30" ItemsSource="{Binding RequiredFields}" OverridesDefaultStyle="False">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Margin="3,0,3,3">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="110"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Content="{Binding Path=Header, Mode=OneTime}" Foreground="{DynamicResource SilverBorderColorBrush}" Grid.Column="0"/>
<TextBox Text="{Binding Path=Value}" HorizontalAlignment="Stretch" Foreground="{DynamicResource SilverBorderColorBrush}" Grid.Column="1"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="DockPanel.Dock" Value="Top"/>
</Style>
</ItemsControl.ItemContainerStyle>
</ItemsControl>
</ScrollViewer>
</Border>
</Grid>
None of the answers below have helped to make this work, but I'm fairly confident that the answers would work in the majority of cases.
My control is hosted within a tab page. It is dynamically loaded in, and I have no control over how the tab page is designed. My gut feeling is that the tab control allows as much space as the content within it. Because the grid in my control is saying use up all the space available, and the tab page offers as much space as the child container needs, and the itemscontrol is trying to use as much space as the grid offers; it culminates in the tab page expanding to contain the entire ItemsControl content.
If the tab page was created to not expand to fit its content, the solutions below would work. Unfortunately, I don't believe this to be the case.
One whole day wasted on this. Time to move on.
Ah yes the intricacies of WPF layout is a pain sometimes. What's killing you is the combination of the DockPanel and the Width="Auto" on your ItemsControl. The DockPanel tells its children that they can have as much space as they want for layout. Your ItemsControl then tells its children the same thing. In the end, the Window creates a ScrollViewer to handle the oversized content.
Replace the outer DockPanel with a grid and all should be well.
To have scrollviewer not to strength, you need to use Grid container
<Grid>
<ScrollViewer DockPanel.Dock="Top" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Visible" CanContentScroll="True" BorderBrush="{DynamicResource PanelBorder}" BorderThickness="1,1,1,1" Background="{DynamicResource LightGradientBackgroundBrush}">
...
</ScrollViewer>
</Grid>
DockPanel and StackPanel always stretch to fit it's children
Also look at this note (i've copied from here)
Panel X Dimension Y Dimension
Canvas No No
Dock Yes Yes
StackPanel
(Vertical) Yes No
StackPanel
(Horizontal) No Yes
Grid Yes* Yes*
WrapPanel No No
Except when using "Auto" rows and columns
Yes in the above table means "Children are stretched to available size"
No in the above table means "Children are their desired size"
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.
