What is the purpose of the validation summary control? What
do you need to do to prevent an error message from being
displayed in a validator when a validation summary control
is used? How can you display a message in both the validator
and the validation summary control?

Answer Posted / pallavi
ASP.NET has provided an additional control that complements the validator controls. This is the validation summary control which is used like:
<asp:ValidationSummary id="valSummary" runat="server"
HeaderText="Errors:"
ShowSummary="true" DisplayMode="List" />
>
The validation summary control will collect all the error messages of all the non-valid controls and put them in a tidy list. The list can be either shown on the web page (as shown in the example above) or with a popup box (by specifying ShowMessageBox="True")
