    I am using a radtreeview bound to a dataset having multiple levels of hierarchy. See attached file radtreeview.gif.

    With AllowEdit=True, I press F2, and edit the text. Then when I hit the enter or escape key, the radtreeview crashes with the an exception "Index -1 does not have a value". See attached file radtreeviewError1.gif

    I noticed that this exception is only thrown for the nodes that do not have children. For nodes having children, it works fine.

    Also I tried to programmatically edit using a context menu and context menu manager. However the same exception is thrown. My code is pasted below.
    private void radMenuItemEdit_Click(object sender, EventArgs e)
                RadTreeNode node = territoryRadTreeView.SelectedNode;

                if (node != null)
                    territoryRadTreeView.AllowEdit = true;

    The version I have is, RadControls for WinForms Q2 2009 SP1.
    I am stuck on this issue for the last 2 days and any help will be appreciated.

    Hello Avinash Tauro,

    Thank you for reporting this issue.

    I am afraid, however, that I could not reproduce the exception. Please provide detailed steps on what needs to be done in order to trigger the exception.
    I am looking forward to your reply.

    Best wishes,

    Hi Avinash Tauro,

    Please note that in Q1 2011 we have introduced a major upgrade of RadTreeView control, which is now virtualized and fully customizable. Feel free to download the latest release and try it out. For more information on our latest release refer to this blog post.
