[2005] How to determine which event has triggered a handler

[trisuglow]

Private Sub cboBuilding_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboBuilding.SelectedIndexChanged, cboBuilding.LostFocus

End Sub

What can I do in the above procedure, which handles two of a combo box's events, to determine which event has called it?

Check if selected index is changed from the previous value then cboBuilding.SelectedIndexChanged is fired otherwise lost focus event is fired.

You're suggesting I have a static variable in the procedure to remember the previous index? Thanks, this would work, but I'm sure there must be a way of finding out which event is being handled.

Obviously I could also write two separate handlers, one to handle each event...

I don't understand how EventArgs contains no information about the event.
