    I really like the single click to expand feature. I would like even more a singleclick to expand and a double click to collapse. Items that are already expanded when selected collapse. This seems wrong to me. You usually select an item to view it not collapse it.

    Hi MiddleTommy,

     I understand your requirement. You can customize the RadTreeView like so:

    <telerik:RadTreeView IsExpandOnSingleClickEnabled="True" ItemClick="RadTreeView_ItemClick" x:Name="tree">
                <telerik:RadTreeViewItem Header="Item a">
                    <telerik:RadTreeViewItem Header="Item b" />
                </telerik:RadTreeViewItem>
            </telerik:RadTreeView>
    private void RadTreeView_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)
           {
               this.tree.IsExpandOnSingleClickEnabled = true;
               if ((e.Source as Telerik.Windows.Controls.RadTreeViewItem).IsExpanded == true)
               {
                   this.tree.IsExpandOnSingleClickEnabled = false;
               }
           }
    Is this suitable for you?
