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"

Here i have two controls NodeXlControl1 and Datagrid1 on page seprated by grid seprator. when window loads NodeXlControl1 does not come within the grid column width and height. i want nodexlcontrol1 should be shown with in the grid column width and height. and i if it goes beyond the limits of width and height of column, scroll bar should come.
If your my:NodeXLControl internally has some scroll viewer (like some ItemsControl or ScrollViewer based child) then simply wrapping my:NodeXLControl in a Grid would do the trick.
StackPanel expands to overflow the children. Grid expands to outer's container's availability of space.
<Grid>
<my:NodeXLControl ... />
Should do the trick.
But if you my:NodeXLControl has no scroll viewer in it then you would need to wrap it inside one and provide absolute width or height to it or wrap it inside a Grid for it to bound to its avilable space and show scrollbars accordingly.
e.g.
<Grid>
<ScrollViewer ...>
<my:NodeXLControl ...>
I'm having trouble getting my UserControl to expand vertically when my window is expanded.
My UserControl currently sits inside a ItemsControl which is stretching correctly by setting the VerticalAlignment="Stretch" property on the ItemsControl.
I add the following UserControl to the ItemsControl:
<UserControl MinWidth="930">
<Grid VerticalAlignment="Stretch" Background="Red">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition Width="730*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="400" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<DockPanel Grid.Column="1" Grid.ColumnSpan="1" Grid.RowSpan="2" Grid.Row="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="Pink" LastChildFill="True">
<ItemsControl Name="itemPanelOverview" Grid.Column="1" Background="Black" Margin="0"/>
</DockPanel>
</Grid>
</UserControl>
The UserControl is called in an ItemsControl inside of a TabControl like so:
<TabItem>
<TabItem.Header>
HEADER EG
</TabItem.Header>
<ItemsControl Name="contentItems" Grid.ColumnSpan="2" Grid.Column="1" Grid.Row="1" VerticalAlignment="Stretch" Background="Blue">
<Grid Height="35" Background="{DynamicResource GrayMenuGradient}" >
<Image Source="..." Stretch="None" />
<TextBlock Text="{Binding WelcomeMessage}" />
</Grid>
</ItemsControl>
</TabItem>
It appears that the ItemsControl (contentItems) is stretching as expected, as I can see the blue background stretching correctly.
I haven't set the height for this UserControl anywhere other than the Row Definitions. Is there something I'm missing?
There are at least two aspects at play here:
The first is that when you have items in an ItemsControl, each item is actually inside an ItemContainer, so it is the container that you want to stretch.
You can design the container by declaring an ItemContainerTemplate for your ItemsControl: http://msdn.microsoft.com/en-us/library/system.windows.controls.itemcontainertemplate.aspx
The second consideration is the ItemsPanelTemplate, which determines into what type of panel the items are placed. The ability of the items in the ItemsControl to fill up the available space is going to depend on the type of container as much as on the type of ItemContainer. For example, if you use a StackPanel for the ItemsPanelTemplate, it won't fill up available space because StackPanel grows and shrinks according to its contents. A DockPanel could potentially work, but only the last child would grow to fill available space. Perhaps a UniformGrid could do the trick.
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>
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 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.
