How can I get ScrollViewer to work inside a StackPanel?

wpf scrollviewer> </grid
wpf scrollviewer not working
wpf scrollviewer mouse wheel not working with stackpanel
wpf scrollviewer style
wpf scrollviewer dynamic height
wpf scrollviewer code behind
xaml page scrollbar
verticalscrollbarvisibility xaml

In the following WPF XAML the ScrollViewer does not work (it displays a scroll bar but you cannot scroll and the contents go off the window to the bottom).

I can change the outer StackPanel to a Grid and it will work.

However, in my application from which I reproduced the following code, I need to have an outer StackPanel. What do I have to do to the StackPanel to make the ScrollViewer show a usable scrollbar? e.g. VerticalAlignment="Stretch" Height="Auto" don't work.

 <StackPanel>
        <ScrollViewer>
            <StackPanel>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
                <TextBlock Text="This is a test"/>
            </StackPanel>
        </ScrollViewer>
 </StackPanel>

You can't without fixing the height of the StackPanel. It's designed to grow indefinitely in one direction. I'd advise using a different Panel. Why do you "need" to have an outer StackPanel?

ScrollViewer not working with StackPanel, After a long night sleeping I solved it by changing the parent StackPanel to a Grid​. I kept the second StackPanel inside ScrollViewer element  The reason was that scrollviewer was not able to estimate it's height inside stackPanel which it was able to do inside Grid. Now I explicitly set the height of the scroll viewer to the height of outside StackPanel and now it worked with my constraint of using a scrollViewer inside stackPanel. So Final solution lookes like following:

This was bugging me for a while too, the trick is to put your stackpanel within a scrollviewer.

Also, you need to ensure that you set the CanContentScroll property of the scroll viewer to True, here's an example:

  <ScrollViewer Grid.Row="1" Margin="299,12,34,54" Name="ScrollViewer1" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" Height="195" CanContentScroll="True">
        <StackPanel Name="StackPanel1" OverridesDefaultStyle="False"  Height="193" Width="376" VerticalAlignment="Top" HorizontalAlignment="Left"></StackPanel>
  </ScrollViewer>

ScrollViewer does not work if Grid is within a StackPanel, This is how the window dictates the limits to the grid (fit inside my frame), grid stiks to this. When you put a StackPanel in the window, it will get the  I'm trying to display image results on a StackPanel, and scroll through the results. However the height of the ScrollViewer is set to the height of the StackPanel instead of the available space in

Notice that sometimes you might have a StackPanel without realizing it. In my case I had this code

<ScrollViewer>
  <ItemsControl ItemsSource="{Binding Pages}"/>
</ScrollViewer>

which worked fine. The "Pages" referenced by the binding was really different, complex UserControls, and I wanted to have only scrollbars on some of them. So I removed the scrollviewer:

 <ItemsControl ItemsSource="{Binding Pages}"/>

And then I put the ScrollViewer as the top element on those of the usercontrols where I wanted them. However, this did not work. The content just flowed off the page. At first i didn't think this question/answer could help me, but the I realized that the default ItemPanel of an ItemsControl is the StackPanel. So I solved my problem by specifying an ItemsPanel that was not the StackPanel:

<ItemsControl ItemsSource="{Binding Pages}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <Grid/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
</ItemsControl>

Scrollbar not working inside stackpanel, Hi, I am using XAMDataGrid inside stack pnale along with few other childs. when there are multiple items in xamdatagrid vertical scrollviewer  The XamDataGrid will automatically place a ScrollViewer around its content, unless it is placed as in your scenario in an infinity container, like a StackPanel, so in order to avoid the behavior about vertical scrollbar, I can suggest to set the HeightInInfiniteContainers property of VewSettings class in XamDataGrid to some default height instead of using ScrollViewer.

Indeed, the way I solved that dileman was to remove the outer stack panel and instead set the scrollviewer in the position I wanted inside the main grid.

        <Grid Style="{StaticResource LayoutRootStyle}">
    <Grid.RowDefinitions>
        <RowDefinition Height="160"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>        

    <!-- Vertical scrolling grid used in most view states -->    

        <ScrollViewer Grid.Row="1" HorizontalScrollBarVisibility="Auto">
            <StackPanel Orientation="Horizontal">
                <GridView>
                ...
                </GridView>
            </StackPanel>
        </ScrollViewer>        

Stackpanel inside a scrollviewer?, So Finally, got this to work how I would expect it to by putting into a temp canvas and then evaluating its bounds to get an actual height/width. If I manually set the StackPanel's Width to 512 (which is the width of the control, so it should be the width of the ScrollViewer and StackPanel by default), then it will not go out the side. However, if I specify the StackPanel's Height to 128 (which is the height of the control), then I still get no vertical scrollbar and they go down as if I

This is how it works:

By binding the ScrollViewer's Height to Window's Inner Height.

The logic of re-sizing is we need to give any element fix height or design the view to use render height.

C# WPF Adding scroll bar in Stackpanel, How about putting the Stackpanel inside a ScrollViewer . Hide Copy Code. <​ScrollViewer HorizontalContentAlignment="Center"  Stackpanel doesn't provide any scrolling. You can wrap it into a ScrollViewer. Also: listView already provides Scrolling. But: The ListView inside stackpanel will pick up all your manipulation events. Also, a ListView inside a Stackpanel will have infinite heigt and therefore loose it's virtualization capabilities.

Implementing Scrolling in Windows using WPF ScrollViewer in C# , The code examples in this tutorial explain use of the Scroll Viewer The code places a TextBlock and a Rectangle control on a StackPanel. Left side of my page I have a vertical StackPanel with the following elements: 1 TextBlock 1 vertical StackPanel with multiple elements that fills the available space I am trying to make the second StackPanel scrollable with a ScrollViewer element but with no success.

WPF ScrollViewer Control, In a StackPanel, controls are "stacked" in one direction. Other controls, not just StackPanel work just as well within a ScrollViewer.StackPanel. Here: I dragged  I have tried StackPanel and Grid and both failed. The StackPanel does not shrink rows at all. The Grid does the same if the top RowDefinition's height is set to "auto" (the ScrollViewer inside does not show its scrollbar). If it's set to a star, the blue text is moved down to at least half of the space (depends of the bottom row's height setting).

Use of StackPanel inside ScrollViewer · Issue #7337 · BabylonJS , Because of the difficulties in updating the sizes it may turn out that there always problems to use a StackPanel with a ScrollViewer. I will have a  Controls inside StackPanel or ScrollViewer are measured with infinity height and that is why the grid will not show scrollbars however you can set explicitly Height for RadGridView to achieve your goal.

Comments
  • wanted to stack things and using the Grid you have to manually manage all the rows and columns, but DockPanel works nicely so I'll switch to that, thanks.
  • I agree with Edward. In my experience, wrapping my DataGrids in a DockPanel then setting DockPanel.Dock="Top" for each DataGrid worked great.
  • Which alternative control should I use in UWP? There isn't DockPanel. Thank you.
  • For UWP you can use RelativePanel
  • Damn stackpanel, I always have to replace it with a grid on UWP, they should change its behavior it's the only panel that works this way
  • Where is the CanContentScroll property? See msdn.microsoft.com/en-us/library/…
  • Giddy> Please see this link:- msdn.microsoft.com/en-us/library/ms612683.aspx
  • "You need to ensure that you set the CanContentScroll property of the scroll viewer to True" --- I still can't believe that this is not the default for a control named "ScrollViewer".
  • @AndreaAntonangeli I don't think 'CanContentScroll' means what you think it means. When 'true' scrolling is done per item (or piece of content), when 'false' scrolling still occurs but at a pixel level
  • It's kinda close, but not quite. Some control that is ancestor to the ScrollViewer, but is between Border and the ScrollViewer, might have a margin (mine does), and the binding to the ActualHeight value won't catch that.
  • @AlanMcBee yes, there can be many possible cases where it will not work perfectly, but this being the most basic case for a control hierarchy I've given the solution. But considering the logic all you need to do in most cases the change the ancestor type in your binding and it should work perfectly again. The crux of the fix was there was an UI element in hierarchy that could help us to depend on a height(not necessarily a Border), the logic can remain same as long as you can find a reliable height. Hope it make sense, else post your problem as a question, I'll try to help. :)
