C textbox validating event not firing
Doing so can cause your application or the operating system to stop responding.For more information, see the WM_KILLFOCUS topic in the "Keyboard Input Reference" section, and the "Message Deadlocks" section of the "About Messages and Message Queues" topic in the MSDN library at I have discovered that the click event only fails to fire if I make a selection in a drop down box first.
Is there any event that fire when the value of the textbox change from a peace of code and when the textbox is validated or lost the focus and the event don't fire on the key press,because I have a lot of calculation and It's not possible to do it on every key press I already tried validating,validated,textchange,keypress,lostfocus Validating and validated and lostfocus is not fired when the textbox value is changed using textbox.text="" and the textchanged is fired on every changed (keypress and paste) any other events [email protected] Gray Sorry I miss your answer before the reply and now your point is clear for me tanks for the help I already try to fire the event validated when the text property is set but the problem is that this property is changed in several places and I have a lot of duplication in my code and it's why I'm researching for this event and please to note that I have 350 textbox and every textbox is changed from at least 5 places If you need to run custom validation logic when you add text to your textbox in code, you will need to invoke whatever method contains the validation logic yourself.
The form largely works as expected but the validating and validated events That sounds like a Winforms/UI problem more than anything.
Have you tried calling your class library code from a straightforward Windows app?
I the issue is not with button events, but with the form becoming blocked after making a selection from a drop down box.
I have not yet discovered why the form blocks after the drop down is selected (it has no events, but does have databinding, so there are some possible causes there). Very sorry about that, it was something I forgot to change while copying my code across and simplifying it for the question.
