SYMPTOMS

In a Web application that was built by using Microsoft ASP.NET 2.0, you try to set the DefaultButton property of a Panel control. When you do this, the Click event for the associated Button control is not raised. This problem occurs when page validation fails and when a validation control on the page cancels the postback behavior.
