ASP.Net How to show multiple validation group on Submit Button (Single Button)

Its little bit complex to show different validation group on signle Submit button click validation

To achieve this or show all validation (which has different validation group ) check below code

Page contains 3 validation groups

1. mailvalidation — Validation for Email Address
2. Uasenamevalidation — Check Username and validation
3. Page — All other Control Validation Group

ASP.Net Button Syntax:

<asp:Button ID="btnSave" runat="server" Text="Submit" OnClientClick="return Validate()" /></pre>

JavaScript Code :

<script type="text/javascript">
function Validate() {
var isEmailValidation = Page_ClientValidate("mailvalidation");
var isUserNameValidation = Page_ClientValidate('Uasenamevalidation');
var isControls = Page_ClientValidate("Page");

if (isEmailValidation && isUserNameValidation && isControls)
return true;
else
var i;
for (i = 0; i < Page_Validators.length; i++) {
ValidatorValidate(Page_Validators[i]); //this forces validation in all groups
}
return false;
}
</script>

In above script Else part forces validation of all groups which are remaining and will show message.
