Best is to go for CustomValidators. Below is a sample code for a custom validator which checks that a textbox should not have zero value


<asp:CustomValidator id="CustomValidator1" runat="server"
ErrorMessage="Number not divisible by Zero"
ControlToValidate="txtNumber"
OnServerValidate="ServerValidate"
ClientValidationFunction="CheckZero" />

Input:
<asp:TextBox id="txtNumber" runat="server" />
<script language="javascript">
<!--
function CheckZero(source, args) {
int val = parseInt(args.Value, 10);
if (value==0) {
args.IsValid = false;
}

else {
args.IsValid = true;
}
}
// -->
</script>
