title: c# AcceptButton and validation
body: <p>Hi
  I have a form which contains of several textboxes and two buttons Cancel and Ok. These buttons are assigned to accept and cancel buttons properties in form. The problem is that I have to validate texts entered in all textboxes. </p>
  
  <p>I want to do that if user click Ok button(which is acceptButton). So I wrote a function which is reponsible for validation and I fire this function if user click Ok button. The problem is that I can't stop form from closing even if validation function return false. It happens because of the fact that I assigned acceptbutto property to my Ok button. Is there any way to prevent form from closing if validation fails without removing acceptbutton properties ??</p>
