ContextMenuOpening for treeview background?

[Kristoffer]

I can easily show a custom menu when right-clicking tree nodes:

this.radTreeView.ContextMenuOpening += new Telerik.WinControls.UI.TreeViewContextMenuOpeningEventHandler(this.radTreeView_ContextMenuOpening);

But this does not trigger when I right-click the treeview background. How can I show a context menu when right-clicking in the white background area?

Hello Kristoffer,

Thank you for writing.

The context menu of RadTreeView is designed to be opened only when a node is right clicked since the context of the menu items are relevant to the clicked node. 

If you want you can show you own context menu when the element is clicked:

    RadContextMenu myMenu = new RadContextMenu();
    RadMenuItem item = new RadMenuItem();
    myMenu.Items.Add(item);
    item.Text = "My item";
    item.Click += item_Click;
..........
void radTreeView1_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == System.Windows.Forms.MouseButtons.Right)
    {
        RadTreeViewElement el = radTreeView1.ElementTree.GetElementAtPoint(e.Location) as RadTreeViewElement;
        if (el != null)
        {
         myMenu.Show(this.PointToScreen( e.Location));
        }
    }
}

 I hope that you find this information useful.
