RadGridView inside RadTabControl loses vertical scroll

[Gaetano Gliatta]

Hi,
I've e RadGridView inside e RadTabControl.

RadGridView loses the vertical scrollbar when its content exceeds the vertical available space.

If I set a fixed Height to RadTabControl the scrollbar appairs, but this isn't my goal.

If I move RadGridView outside RadTabControl the scrollbar appairs.

No controls have fixed Height in the page becouse I want that the page extends itself vertically for all space available.

Any ideas? There is a bug or I'm missing something?

Thank you in advance for your attention.

Kind regards

Hello Gaetano,

I am not quite sure how you define your RadGridView inside RadTabControl, but I suppose that the issue came from the Grid layout container that is added by default to a RadTabItem. RadGridView placed in a Grid container with RowDefinition/ColumnDefinition's  Height/Width set to Auto will measure its children with infinity and the scrollbar will not appear.

    x:Class="SilverlightApplication194.MainPage">

    <Grid x:Name="LayoutRoot"  Background="White" DataContext="{Binding Source={StaticResource SampleDataSource}}">
        <telerik:RadTabControl >
            <telerik:RadTabItem Header="RadTabItem">
                <Grid Background="Transparent">
                    <Grid.RowDefinitions>
                        <RowDefinition Height="*"/>
                        <RowDefinition/>
                     </Grid.RowDefinitions>
                    <telerik:RadGridView Grid.Row="0" ItemsSource="{Binding Collection}"/>
                </Grid>
            </telerik:RadTabItem>
        </telerik:RadTabControl>

    </Grid>
</UserControl>

Thank you so much, it runs!

Row height must be 

<RowDefinition Height="*"/>

and not Auto.

Kind regards
