TabControl CompositeCollection

[AdaDog]

Does the TabControl.ItemsSource property support CompositeCollection?


<TabControl> 
    <TabControl.ItemsSource> 
        <CompositeCollection> 
            <TabItem Header="Extra Tab" /> 
            <CollectionContainer Collection="{Binding Items}" /> 
        </CompositeCollection> 
    </TabControl.ItemsSource> 
</TabControl>>

Hi Doug Simpson,

I guess you are asking whether this is possible in RadTabControl for WPF. Currently this cannot be achieved in this control. We logged this as a feature request in our PITS where you are able to vote for and this way increase its priority. Thank you for your cooperation.

Here's a way to do it.

<TabControl DataContext={Binding}>
    <TabControl.Resources>
        <CollectionViewSource Source="{Binding Path=Items}" x:Key="ItemsCollectionViewSource"/>
    </TabControl.Resources>

    <TabControl.ItemsSource>
        <CompositeCollection>
            <TabItem Header="Extra Tab" />
            <CollectionContainer Collection="{Binding Source={StaticResource ResourceKey=ItemsCollectionViewSource}}" />
        </CompositeCollection>
    </TabControl.ItemsSource>
</TabControl>

Hi Doug Simpson,

Yes, we know this could be achieved in the System.windows.controls.TabControl. Unfortunately, it cannot be achieved in the current telerik`s RadTabControl for WPF.

All the best,
