.NET Forum / Languages / VB.NET / July 2007Canceling Event Processing on a control
I know about AddHandler and RemoveHandler, but my requirement is a little more complex. I pass a form to a routine. In that routine I must scan each control, and for each "button" control I find, I must delete it's "click" event handler. I can't see how to do this using RemoveHandler because I don't know the name of the delegate handling the event. So, somehow, having just the control, I need to dynamically see if it's "click" event is being handled, and by what routine. Is there a way to find out if a "click" event is being handled for a control, and then removing that event handler? BTW I'm still using .Net 1.1 if it makes a difference. Thanks, John There is a protected readony property Events on forms, that details all of the attached event delegates. Because it is protected you may need to add your code to the form instead of the external routine, and then call the form code from your routine. >I know about AddHandler and RemoveHandler, but my requirement is a little >more complex.

I set a breakpoint in the form code and tried to look at "me.events" which got me to a list the quickview couldn't display, so I tried "me.events.item(0)" and it had a value of nothing. "me.events" is returning a eventhandlerlist, but that list seems to be empty. I tried playing around with it for awhile and couldn't get anything. Could you be a little more specific on what I need to do? Thanks, John > There is a protected readony property Events on forms, that details > all of the attached event delegates.
