The ValidatorCalloutExtender control in Ajax extends the functionality of the existing ASP.NET validation controls.

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" />
<asp:RequiredFieldValidator ID="RFD" runat="server"
ControlToValidate="TextBox1" ErrorMessage="Textbox should not be empty" Display="None"></asp:RequiredFieldValidator>
<ajaxToolkit:ValidatorCalloutExtender
runat="Server"
ID="ValidatorCalloutExtender 1"
TargetControlID="RFD"
Width="350px"/>
