How can the default focus can be set when a error occurs?

We can set SetFocusOnError="true" for the ASP.NET validators, So that the first control with the validation error will receive the default focus when the form is submitted.

First Name: <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:RequiredFieldValidator SetFocusOnError="true" ErrorMessage="TextBox1 is empty" ID="RequiredFieldValidator1" ControlToValidate="TextBox1" Display="Dynamic" runat="server">* </asp:RequiredFieldValidator>
Last Name: <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> <asp:RequiredFieldValidator SetFocusOnError="true" ErrorMessage="TextBox2 is empty" ID="RequiredFieldValidator2" ControlToValidate="TextBox2" Display="Dynamic" runat="server">* </asp:RequiredFieldValidator>
Here SetFocusOnError is set to true for the validation control, so that the TextBoxes gets focused when it is empty.
