Horizantal Scrollbar for GridView not visible

[Ejaz]

I have a simple GridView placed inside a Grid. I'm setting the ItemsSource from C# with auto-generating columns. The vertical scrollbar works fine but the horizontal scrollbar just refuses to show up. This is the code I'm using

WPF

<Grid>
        <telerik:RadGridView Name="telerikGrid" AutoGenerateColumns="True" ></telerik:RadGridView>
</Grid>

telerikGrid.ItemsSource = TableSource;

TableSource is an ObservableCollection of dynamic ExpandoObject. This UserControl is placed in a RadTabItem of another UserControl which in turn appears in a RadPane in the MainWindow.

Hello,

Have you eventually placed RadGridView in a StackPanel with Orientation="Horizontal"?

Not a stackpanel, I've placed it in a wrap panel with horizontal orientation.

Hello,

Then, this should be the reason for the missing scroll bar. I would not recommend you defining RadGridView (or any virtualized control) in such a container as it measures its content with infinity and the virtualization of the grid will be broken. Please take a look at our online documentation for an additional information.

You could place it under a Grid.Row with Height different than Auto instead.

Let me know how this works for you.

I know this is a problem with the container, what I'm unable to figure out is, which container. I have another radgridview in a usercontrol, which is also placed in the same WrapPanel but the horizontal scroll works pretty well for this.  I'll try to explain the scenario a little better .

This is my usercontrol which contains my RadGridView.

<UserControl x:Class="UC">
<Grid>
<telerik:RadGridView Name="telerikGrid" AutoGenerateColumns="True"></telerik:RadGridView>
</Grid>
</UserControl>

<UserControl x:Class="UCMain">
       <Grid>
            <telerik:RadDocking>
                <telerik:RadDocking.DocumentHost>
                   <telerik:RadSplitContainer>
                      <telerik:RadPaneGroup>
                         <telerik:RadPane Header="Newpane">
                            <telerik:RadPane.Content>
                                <controls:UC />
                             </telerik:RadPane.Content>
                           </telerik:RadPaneGroup>
                         </telerik:RadSplitContainer>
                       </telerik:RadDocking.DocumentHost>
                    </telerik:RadDocking>
             </Grid>
</UserControl>

And finally the MainWindow

<Window x:Class="MainWindow">
<Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Grid grid.Row="0">
                <WrapPanel Name="wrapPanel" />
        </Grid>
</Grid>
</Window>

The usercontrol 'UCMain' is added to the wrapPanel in C#. Hope this gives you a better picture.

Hi,

I tested placing RadGridView under WrapPanel and as a result the horizontal scroll bar displayed fine. I also tested placing RadGridView under RadPane, similar to the code snippet you shared. It also worked good.

I attached my test project. Would you please try modifying it so that the issue is reproduced?
