Sync between RadTreeView and RadCarousel

[Vien Nguyen]

I am using both a RadTreeView and a RadCarousel and bind the root nodes of the tree view and the carousel to the same list of items. If the user change the selection on one control, I would like the app to automaticall change the selected item on the other control. I tried to bind the SelectedItem property on both control to the same object but that did work. Has anyone tried this before?  Thanks.

Hi Vien Nguyen,

You may bind the SelectedItem of both the RadCarousel and RadTreeView to a property in your ViewModel for example:

<telerik:RadTreeView x:Name="treeView" ItemsSource="{Binding Clubs}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}" />
        <telerik:RadCarousel x:Name="carousel" ItemsSource="{Binding Clubs}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}" Grid.Row="1" />

However, this will be applicable only if the item you want to select from the TreeView is visible in the RadCarousel. Otherwise, you may handle the SelectionChanged event of the TreeView and set the selected item of the Carousel:

private void treeView_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            foreach (var item in e.AddedItems)
            {
                this.carousel.BringDataItemIntoView(item);
                this.carousel.SelectedItem = item;
            }
        }

Do let me know whether the suggested approach fits into your requirements.

Hi Vien Nguyen,

I am sending you the sample project I created for the case. Please take a look at it and let me know if it differs from your settings and requirements. If needed, feel free to change it in the way you want and send it back so that I can seed your particular scenario.
 

All the best,

Thanks for the example. It works when selection on the tree is changed. How do I make it so that scrolling through the carousel also scroll through the tree. Thanks.
