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.
