Validating event net speed dating in usa
The Cell Validating event occurs always before the Cell Validated event when the edited cell is about to lose its focus.If the focus is moved to a cell in the same row, then no other events occur.I didn't want to adjust the forms (legacy app) as I'm using this in a base class, but this seems to resolve this bug. The WM_CLOSE event fires AFTER the WM_SYSCOMMAND / SC_CLOSE and you can restore the value. Of course, there was lots of more cool features involved but for the sake of this post I'll keep it simple.The code I chose to implement the above scenario involved the Validating & Validated events: However, all I wanted to do was exit the form in the first place and not spend the extra cycles querying the database or making things happen on the form before closing.They occur when the new content entered by the user is about to be committed.
( Unless I'm reading it wrong, it describes the problem exactly, but the solution doesn't work. Remember to set to false the Causes Validation = false of the exit button Also you can put it in the mouse down even or Closing Form Event, any event that triggers before the validating event. IT is so annoying working with MS buggy implementation.
What was making it tough was the validating event was firing before any other event. *giggle* So I jigged up the following code: I tossed the above code at the beggining of my Validating event, typed a couple letters in the box, click the infamous (more famous than famous) Mr.
I searched google for some ideas and I came across the following snippet of code So, at my wits end, the only concievable way I could think of getting around this problem was knowing when the close event was coming up in the near future and then...*BAM! 'x', and the form closed (insert best Arny voice) IMMEDIATELY. We use a plug-in architecture to load User Controls at runtime. Cancel in the Validating event of a plug-in prevented the host Form from shutting down properly.
thx and regard,s Norton Norton, I got the following tip from "Windows Forms Programming in C#" by Chris Sells, from Addison Wesley. How can something be wrong in a textbox when you use correct the validating event.
Within your "Accept" button click handler (the "save" button) process each control that Causes Validation to ensure that they are all valid... (Assuming you are not placing conflicting date in there by the program) It will be executed as that control looses the focus. Cor Phill, Now I understood you, in fact do you want to check if they are not empty?
