Hello VikasChablani,

Probably you would be able to hadnle the key down event like the following:

      private void ultraTree1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyData == Keys.F2)
            {
                Debug.WriteLine("F2 is pressed");
            }
        }
 

Please let me know if you have any other questions on that matter.
