Your question is exceedingly ambiguous.

This may help.[^]

Another thing that may help is if you provided a more succinct question with more detail as to what you are attempting.

<asp:TemplateField HeaderText="Email Address" ControlStyle-CssClass="cssWidth">
<itemtemplate>
<asp:Label ID="LblEmail" runat="server" Text='<%#Bind("adminusername") %>'>
<edititemtemplate>
<asp:TextBox ID="TxtEmail" runat="server" Text='<%#Bind("adminusername") %>'>
<asp:RequiredFieldValidator ID="RFVEmail" runat="server" Display="Dynamic" ControlToValidate="TxtEmail"
ErrorMessage="Required">
<asp:RegularExpressionValidator runat="server" ID="REVEditEmail" ErrorMessage="Incorrect Email" ControlToValidate="TxtEmail">

<insertitemtemplate>
<asp:TextBox ID="TxtInsertEmail" runat="server">
<asp:RequiredFieldValidator ID="RFVEmail" runat="server" ControlToValidate="TxtInsertEmail"
ErrorMessage="Required">
<asp:RegularExpressionValidator ID="REVEmail" runat="server" ControlToValidate="TxtInsertEmail" ErrorMessage="Invalid Email" ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*">
