Vb net lostfocus validating
So, which is the better option, in terms of both efficiency and industry-standards?You should always use the Validating event, it was made to support validation.Handle the Cell Validated event to perform post-validation processing.For more information about handling events, see NIB: Consuming Events.I don't want any validation for the edit box to be executed. Here is an important detail: if the validation fails, then If the validation occurs when the edit box loses focus, nothing about the the cancel button is going to stop that from happening.However, if the failing validation is preventing the cancel button from doing its thing, set the @Daniel Schaffer: i'm not sure if I understand the "however"-part correctly.If the buttons parent has Causes Validation set to true, the validating event will still get called.
Best thing to do is to delay your code until everything is done running and the form goes idle again. Caution Do not attempt to set focus from within the Enter, Got Focus, Leave, Lost Focus, Validating, or Validated event handlers.Doing so can cause your application or the operating system to stop responding.In the end I did this programatically as it was simpler than going through all the forms...// The flag private bool _is Closing = false; // Action that avoids validation protected override void On Closing(Cancel Event Args e) // Validated event handler private void txt Control To Validate_Validated(object sender, Event Args e) // Do validation on complete so you'll remain on same thread void worker_Run Worker Completed(object sender, Run Worker Completed Event Args e) // Give a delay, I'm not sure this is necessary cause I tried to remove the Thread.
