How to Use ToolTipTextNeeded

[Sade]

I want to show some text when user hovers the level 3 nodes of treeview using ToolTipTextNeeded event. How can I do this?

Hello Sade,

Thank you for writing.

You need to check the node level. For example:

private void RadTreeView1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
{
    var node = sender as TreeNodeElement;
    if (node != null && node.Data.Level == 2)
    {
        e.ToolTipText = "test";

    }
}

Let me know if I can assist you further.
