    I have just downloaded the trial to asses the suitability of the control for an upcoming project.

    I am trying to get the load on demand working.
    When I try to follow the example the event is fired but on the screen a spinny arrow icon just goes round and round.

    Could you please advise.


    <telerik:RadTreeView Height="250" HorizontalAlignment="Left" Margin="18,24,0,0" Name="radTreeView1" VerticalAlignment="Top" Width="150" IsLoadOnDemandEnabled="True" LoadOnDemand="OnLoadOnDemand"/>

    private void OnLoadOnDemand(object sender, Telerik.Windows.RadRoutedEventArgs e)



    RadTreeViewItem item = e.OriginalSource as RadTreeViewItem;


    // Adding child items


    RadTreeViewItem product = new RadTreeViewItem();

    product.Header =




    product =


    new RadTreeViewItem();

    product.Header =

    Hello Ashley,

    You can stop the loading indication by setting the RadTreeViewItem.IsLoadingOnDemand property to False as described at the bottom of this article.
