Validating cancel

23 Jan

I have a form with one email field, a submit button, and a cancel button.When I type an incomplete address in the email field, and then, without clicking anywhere else on the page, click cancel, the validator checks the email field, displays the invalid message next to the field, and kills the cancel action. I added the "cancel" css class to my cancel button, but it had NO effect.If there is no problem, the error will be null, which will cause the error indicator on the dialog to go the command Button, only the button should be processed.

If the Validating event is not canceled, the dialog will get notified with the Validated event: Since each control has Causes Validation set to true by default, to allow the user to cancel the dialog without entering valid data, make sure to set the Causes Validation property to false for your Cancel or Close button: As much as I lean on the message box in my test development, I prefer not to use it for actual applications.I'm using the jquery validate plugin for form validation.I'm seeing something weird with the cancel functionality. I have a Windows Form with an edit box and a Cancel button. The code is executed every time the edit box loses focus.When I click on the Cancel button I just want to close the form.The following code example uses the derived class Text Box and validates an e-mail address that the user enters.If the e-mail address is not in the standard format (containing "@" and "."), the validation fails, an Error Provider icon is displayed, and the event is canceled.Enabling the low power consumption and constant connectivity of modern standby is a test and validation challenge for the system integrator.All components in the system—hardware and software—must work together to quickly turn power on and off while maintaining connection to the Internet.This behavior was achieved by dragging an Error Provider component onto the dialog and handling the Validating event like so: Notice the call to Error Provider.Set Error, passing in the control the error is associated with (which we get from the sender argument to the Validating event), along with the error string, which will be used as the tool tip.
