Hi teja,


If certain field is mandatory then use "RequiredFieldValidator"
To compare two values , use "CompareValidator" (Like password match)
For email - use "RegularExpressionValidator"

See the following code to use all these validators.



<%@ Page Language="C#" AutoEventWireup="true" CodeFile="RegistrationForm_withvalidations.aspx.cs" Inherits="Forum_Topics_RegistrationForm_withvalidations" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
Enter Name:<asp:TextBox id="txtName" runat="server"></asp:TextBox>
<br />
<asp:RequiredFieldValidator ID="RFV1" runat="server" ControlToValidate="txtName" ErrorMessage="Name is must"></asp:RequiredFieldValidator>
<br />
Enter Password:
<asp:TextBox ID="txtPwd" runat="server"></asp:TextBox>
<br /><br />
Confirm Password:
<asp:TextBox ID="txtConfirmPwd" runat="server"></asp:TextBox>
<br /><br />
<asp:CompareValidator ID="CV1" runat="server" ControlToValidate ="txtConfirmPwd" ControlToCompare ="txtPwd" ErrorMessage="Password and Confirm Password does not match">
</asp:CompareValidator>
<br />
<asp:TextBox ID="txtEmail" runat="server" MaxLength="50" Width="140px"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
ControlToValidate="txtEmail" ErrorMessage="*Invalid Email."
ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator>

</div>
</form>
</body>
</html>
