ASP.NET

firstly I describe situation:

From web page if i insert record successfully then no problem but if some error occur like email id already exist then it focus to the email id text box rather then other.

In .aspx

<asp:TextBox ID="txtEmailId" runat="server" Width="30 %"  />
                            <asp:RequiredFieldValidator ID="RequiredFieldValidator7" Display="Dynamic" ValidationGroup="addClient"
                                runat="server" ErrorMessage="Please enter Email Id" ControlToValidate="txtEmailId"
                                Width="30 %" SetFocusOnError="true"></asp:RequiredFieldValidator>

In .aspx.cs

catch (SqlException sql)
           {
               //ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('Email ID already exist !!!');window.location.href='ClientRegistraion.aspx';", true);
               Response.Write("<script language=javascript>alert('Email ID already exist !!!')</script>");
               txtEmailId.Focus();
               RequiredFieldValidator7.Enabled = true;

           }

thanks in advance.
