Determining POstBack Button in code behind VB

Reply Quote

I am trying to determine if the user clicked the Save or Send button from the toolbar.

HEre's what I have:

Dim C As System.Web.UI.WebControls.CommandEventArgs

If String.Compare(C.CommandName, "Save", True) = 0 Then

End If

If String.Compare(C.CommandName, "Send", True) = 0 Then

END IF

WHAT I GET BACK IS THIS

Object reference not set to an instance of an object.
