How can I know if a .net event is already handled?

Question

I\'ve written some code to handle an event as follows:

AddHandler myObject.myEvent, AddressOf myFunction

It seemed that everything was work

Answer 1

You may use IsHandleCreated property to check your event already has an handle or not.

  If e.Control.IsHandleCreated = False Then
            AddHandler e.Control.KeyPress, AddressOf TextBox_keyPress
  End If
