                </Telerik:RadTreeViewItem>

Hello Bill,

Let me make a quick clarification. IsEditable is property of the RadTreeView control and if you want to enable editing the header of its RadTreeViewItems you have to do it like this:

<telerik:RadTreeView x:Name="xTree" IsEditable="True" IsExpandOnSingleClickEnabled="True">
    <telerik:RadTreeViewItem Header="Root level item 1" IsExpanded="True" >
        <telerik:RadTreeViewItem Header="Second level item 1.1" />
        <telerik:RadTreeViewItem Header="Second level item 1.2" />
        <telerik:RadTreeViewItem Header="Second level item 1.3" />
    </telerik:RadTreeViewItem>
</telerik:RadTreeView>

By using this snippet all items defined in the control will be editable. For more information you can read this article. In order to restrict which items can be edited you have to handle the PreviewEditStarted event of the RadTreeView control and based on custom logic to decide whether to edit or not. Here is sample snippet:

private void xTree_PreviewEditStarted(object sender, Telerik.Windows.Controls.RadTreeViewItemEditedEventArgs e)
{
    if (e.OldValue.Equals("Root level item 1"))
    {
        e.Handled = true;
    }
}
