XAML/WPF - ScrollViewer which has StackPanel inside is not scrolling

wpf scrollviewer not working
scrollviewer wpf horizontal-scrolling
wpf scrollviewer mouse wheel not working
wpf scrollviewer> </grid
wpf textblock scrollviewer scroll to end
wpf scrollviewer dynamic height
wpf scrollviewer> </grid
wpf scrollviewer auto scroll to bottom

I have the following StackPanel inside a ScrollViewer that shows User Control elements Whenever a specific event occurs:

Note: many UserControls might appear in the StackPanel that's why I added a Scrollviewer

<ScrollViewer 
        VerticalScrollBarVisibility="Auto"
        Grid.Row="2"
        CanContentScroll="True" 
        Grid.ColumnSpan="2">

        <StackPanel Orientation="Vertical">
            <ItemsControl ItemsSource="{Binding UserControls}">
                <ItemsControl.ItemTemplate>
                    <DataTemplate>
                        <views:UserControl/>
                    </DataTemplate>
                </ItemsControl.ItemTemplate>
            </ItemsControl>
        </StackPanel>
</ScrollViewer>

Although, the StackPanel is still going out of range and the scroll bars doesn't show and doesn't work!

I tried fixing the height of both the StackPanel and the ItemsControl but it does't seem to work either...

Window Layout containing the ScrollViewer:

<Grid Margin="0,15,0,0">

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>

    <Label 
        Content="This is a Label" 
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Margin="5,5,0,0"
        FontSize="15"
        Grid.Row="0" Grid.ColumnSpan="2">
    </Label>


    <StackPanel Grid.Row="1" Orientation="Horizontal" Grid.ColumnSpan="2">
        <ComboBox
            ItemsSource="{Binding Something}"
            Text="Confirm with..."
            SelectedItem="{Binding Something}"/>
        <Button
            HorizontalAlignment="Left"
            Margin="5"
            Content="Add new UserControl"
            Command="{Binding Path=AddUserControl}"/>

    </StackPanel>

    <ScrollViewer 
        VerticalScrollBarVisibility="Auto"
        Grid.Row="2"
        CanContentScroll="True"
        HorizontalScrollBarVisibility="Auto">
        <StackPanel Orientation="Vertical">
            <ItemsControl ItemsSource="{Binding UserControls}" Height="300">
                <ItemsControl.ItemTemplate>
                    <DataTemplate>
                        <views:UserControl/>
                    </DataTemplate>
                </ItemsControl.ItemTemplate>
            </ItemsControl>
        </StackPanel>
    </ScrollViewer>

</Grid>

Here's my UserControl that is added to the StackPanel Inside the ScrollViewer:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>

    <StackPanel
        Orientation="Horizontal" 
        Grid.Row="0">

        <Button
            Name="DeleteFilter" 
            HorizontalAlignment="Left"
            Margin="5"
            Content="-"/>

        <ComboBox 
            Margin="5"
            IsEditable="False"
            IsReadOnly="True"
            Width="150"
            ItemsSource="{Binding SomeObject}"
            DisplayMemberPath="Name"
            SelectedItem="{Binding SomeObjectProperty}"/>

        <ComboBox 
            Margin="5"
            IsEditable="False"
            IsReadOnly="True"
            Width="150"
            ItemsSource="{Binding AnotherObject}" 
            DisplayMemberPath="Name"
            SelectedItem="{Binding AnotherObjectProperty}"/>

        <TextBox 
            x:Name="Value"
            Text="{Binding TextBoxValueString}"
            TextAlignment="Center"
            Width="100"
            Margin="5"
            Visibility="{Binding TextBoxVisibility}"/>

    </StackPanel>

</Grid>

I'm new to XAML and WPF.

Any Suggestions?

ScrollViewers and StackPanel don't work well together. This is because a StackPanel measures its child elements with infinite horizontal space if its Orientation property is set to Horizontal and infinite vertical space if it is set to Vertical. Please refer to my answer here for more information:

How to scroll the datagrid in stackpanel?

So you should replace the StackPanel with another Panel or remove it altogether:

<ScrollViewer 
        VerticalScrollBarVisibility="Auto"
        Grid.Row="2"
        CanContentScroll="True"
        HorizontalScrollBarVisibility="Auto">
        <ItemsControl ItemsSource="{Binding UserControls}" Height="300">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <views:UserControl/>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
</ScrollViewer>

ScrollViewer does not work if Grid is within a StackPanel, Windows Presentation Foundation (WPF) xmlns="http://schemas.microsoft.com /winfx/2006/xaml/presentation" When you have no stackPanel, the grid will have to adjust its size to that of the When you put a StackPanel in the window, it will get the same I want to scroll the content of the grid only. 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.

I was able to get it run with this setting:

   <ScrollViewer  HorizontalScrollBarVisibility="Disabled"
                 VerticalScrollBarVisibility="Auto"
                 Grid.RowSpan="10">
    <StackPanel Orientation="Vertical"
                Grid.RowSpan="6"
                Name="SPanel"
                Margin="0,0,-0.4,1.4"
                CanVerticallyScroll="True">
      <Border BorderBrush="Black"
              BorderThickness="1"
              Margin="3"
              Grid.Row="0"
              Name="ChartHolder0">
        <dvc:Chart Cursor="Cross"
                   Background="#FFFFFCF2" />
      </Border>
      <Border BorderBrush="Black"
              BorderThickness="1"
              Margin="3"
              Grid.Row="0"
              Name="ChartHolder0">
        <dvc:Chart Cursor="Cross"
                   Background="#FFFFFCF2" />
      </Border>
      <Border BorderBrush="Black"
              BorderThickness="1"
              Margin="3"
              Grid.Row="0"
              Name="ChartHolder0">
        <dvc:Chart Cursor="Cross"
                   Background="#FFFFFCF2">
        </dvc:Chart>
      </Border>
    </StackPanel>
  </ScrollViewer>

And this is what I get:

Implementing Scrolling in Windows using WPF ScrollViewer in C# , At design-time, the element in XAML represents a ScrollViewer control. scrolling functionality in WPF Windows apps using C# and XAML. The code places a TextBlock and a Rectangle control on a StackPanel. It has four values - Auto, Disabled, Hidden, and Visible that are self-explanatory. In mostĀ  In order for the Scrollviewer to work, its container size must be known. One way that you can do this is by setting the MaxHeight property of the extender control to a value where you want the expander to start scrolling.

You are missing a Background for either the StackPanel or ItemsControl(Your choise). Default Background is Null. With Background Null, the ScrollViewer doesn't get mouse events for the mouse wheel, and doesn't scroll.

Scrollbar not working inside stackpanel, Scrollbar not working inside stackpanel when there are multiple items in xamdatagrid vertical scrollviewer not displaying even I have made. 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.

[Solved] How to implement scrollbar on itemscontrol?, My whole XAML View: wpf controls - WPF: ItemsControl with scrollbar ( ScrollViewer) - Stack To help understand the problem, here are the default templates By putting the StackPanel inside a ScrollViewer , the ItemsControl is Note: I have removed the fixed height from the StackPanel Control in theĀ  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.

Stackpanel inside a scrollviewer?, Is this possible, I have tried many ways to get a stackpanel inside the a scrollviewer in pretty much the same way that the full WPF framework Can you modify the code I posted to show how to reproduce the problem? As you can see in the code, the outer ScrollViewer contains a Grid which contains the inner ScrollViewer. With the code above, the outer ScrollViewer functions perfectly, but scrolling with the inner ScrollViewer does not work. If I remove the outer ScrollViewer, the inner ScrollViewer works fine (but, of course, that removes some of my scrolling).

WPF ScrollViewer Control, And then it automatically allows scrolling of the interior area. To use a Other controls, not just StackPanel work just as well within a ScrollViewer.StackPanel. The ScrollViewer class in C# and .NET represents a WPF ScrollViewer control at run-time. At design-time, the &lt;ScrollViewer&gt; element in XAML represents a ScrollViewer control. The code examples in this tutorial explain use of the Scroll Viewer control and how to implement scrolling functionality in WPF Windows apps using C# and XAML.

Comments
  • Can you please show the whole layout code in reference of what parents the scroll viewer has and what properties are set on them?
  • Your code is working fine on my machine, are you by chance overriding the style of the Scroll Viewer somewhere in your application?
  • Well that's weird. No, Not really. I'm not overriding it.
  • Dear @mm8, this is the second time you answer my stackoverflow questions and you nailed it, twice :) ... Thank's a lot. Works perfectly!
  • Do you mean something like this: Background="LightGray"... If you do, then No, it didn't work. The panel still goes out of the window's range
  • The background has nothing to do with the visibility of a scroll viewer
