Vb net leave validating
I've even tried to set for the cancel button and all the parents of the cancel button. It seemed that if the user was in the middle of editing a field that was using validation and just decided to give up (leaving the field with an invalid input), the cancel button event was being fired but the window would not close down.
This was fixed by the following in the cancel button click event: Setting Causes Validation to false is the key, however this alone is not enough.
If the buttons parent has Causes Validation set to true, the validating event will still get called.
In one of my cases I had a cancel button on a panel on a form, so I had to set Causes Validation = false on the panel as well as the form.
If a user is tabbing through the form and tabs from the text box, the validating/validated events are fired. Once the value is cached, the next time the user tabs through the box, the validating event will check to see if the _Cache is different from the . If so that is when I would like to raise the validating event to the parent form (as well as the validated event).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.
