Without being able to see your code, it's hard to really understand what you are trying to do. But in general, if you want two different controls to perform the same code you can just add both to the Handles part of the Event Handler. For example, if you have Button1 and Button2 and you want them to do the exact same think when clicked you would have this:
(It's in VB, but you should be able to see what I'm talking about)
Private Sub Buttons1and2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click, Button2.Click
End Sub
