ASP.NET in a Nutshell

ValidationSummary

Synopsis

The ValidationSummary control receives the error text messages from all validation controls on the Web Forms page and presents them in a single paragraph or list. This occurs automatically on post back, provided that the ShowSummary property is set to True. Alternatively (or in addition), you can set the ShowMessageBox property to True to display a message box with the summary when validation errors occur. This message box uses client-side JavaScript and will be provided only if the browser supports it and the EnableClientScript property is set to True. You can also add a title to the summary by using the HeaderText property.
