Multiple Handles clause: which control fired the event?

I have one control DoubleClick event that handles the DoubleClick events for
multiple controls. The .Tag property contains a different string value in
each control that I would like to examine. How can I get the .Tag property
value no matter which control was double clicked? Reflection?

Thanks,
Dean S

You can retrieve the original control via the "Sender" parameter.

You don't need reflection, you can just cast the sender paramter to
control, and then you will have access to the Tag property:

Private Sub DoubleClick (ByVal sender As Object, ByVal e As EventArgs)
Dim ctrl As Control = DirectCast (sender, Control)
Dim stringValue As String = DirectCast (ctrl.Tag, String)

' Do stuff with stringValue
End Sub
