Vb net cancel validating event

After the validating event returns without being cancelled, meaning we have valid user input, then the validated event will be raised.

In this case, we simply clear any error messages in the error provider.

The error provider simply takes a control and a message in the Set Error method and does the rest of the work for you!

Show("Error - Field Required", "Field Required", _ Message Box Buttons. However, I have a button on my UI that allows the end user to quit without saving so if they go into the form in add mode but don't enter anything in the text boxes (I have 4 set up like this), they get error messages.

Focus() End If End Sub ------------ I have several of these coded and they work fine.

However, I prefer to call it explicitly and handle all validation at once since you most likely will take action only if the entire control’s children pass validation. The most important thing to recognize here is how precise you can be with the validation error message in the error provider.

There are 2 code paths for validation failure, and in each case we provide the user with an appropriate error message.

Working with Super Validator from Code When working with Super Validator using VS. If you have dialog form with validation attached to the controls and validation type is set to per-control or container, to be able to close the form as response to Cancel button being clicked you would simply disable validator by setting Enabled property to false: Then you can close your form as usual using Close method.
