Who handled my event

Question

0.00/5 (No votes)

See more:

I have registered to a LostFocus event on a TextBox and yet the event is not catch - my guess is that someone else handled it.
I've tried using snoop but it only shows me the MouseDown and MouseUp events (and I need the LostFocus).
Any ideas on how can I find out?

Thanks

Update:
code sample for registering to the event

eventInfo.AddEventHandler(cloningObject, eventDelegate);

My guess is that you really did not register to catch the event. But that is just a guess since you did not post your code where we could possibly see where you might have gone wrong.

Updated the question to show the location where I register to the event - not so clear but debugging shows I'm registering correctly.

You shouldn't be using LostFocus, you should use the Enter and Leave events.

See here:

MSDN LostFocus Event[^]

The LostFocus event may not fire depending on how the UICues are handled. Either way, there is no way to cancel a LostFocus event, so even if somebody else did attach to it, it wouldn't unattach your event handler or stop it from being called.

What does the first sentance means: "The LostFocus event may not fire depending on how the UICues are handled"? UICues???

Please read the first note in the link I posted, it has a reference to UICues, which is a flag enumeration for the UI cues on the object. Either way it boils down to use the Enter and Leave events instead of LostFocus.

Didn't understood it all the way, and I'm also not happy with the state, but I'll try and find another way to get what I need. Thanks
