GridHeaderCellElement elementUnderMouse = this.radGridView1.ElementTree.GetElementAtPoint(e.Location) as GridHeaderCellElement;
if (elementUnderMouse == null && e.Button== System.Windows.Forms.MouseButtons.Right)
{
Console.WriteLine("MouseDown");
}
}
I hope this information helps. Should you have further questions I would be glad to help.
