Answer / sravanthi kilari

Insert Custom Validator Control and then write the custom
function. If Other Validation Controls did't meet our

How do you use a custom validator? When might you want to use one?..

Answer / pallavi

Field: <asp:textbox id="textbox1" runat="server">
<asp:CustomValidator id="valCustom" runat="server"
ControlToValidate="textbox1"
ClientValidationFunction="ClientValidate"
OnServerValidate="ServerValidate"
ErrorMessage="*This box is not valid" dispaly="dynamic">*
</asp:CustomValidator>

ClientValidationFunction is usually a javascript funtion included in the html to the user. OnServerValidate is the function that is server-side to check for validation if client does not support client-side validation.
