    How to write a script for alerting select at least one radio button

    I have written a code where I will get the selected text of radio button in an alert, but what I need is if user clicks on select with out selecting any radio button I would like to show an alert form the script. This is my code

    Code:
    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="Default5" %>
    
    <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
    <!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">
          <ext:ResourceManager ID="ResourceManager1" runat="server" />
        <div>
            <ext:FormPanel ID="frm" runat="server">
                <Items>
                    <ext:RadioGroup ID="RadioGroup1" runat="server" FieldLabel="Votre Sex ">
                        <Items>
                            <ext:Radio ID="Radio1" runat="server" BoxLabel="Male" />
                            <ext:Radio ID="Radio2" runat="server" BoxLabel="Female" />
                        </Items>
                    </ext:RadioGroup>                
                    <ext:Button ID="Button1" runat="server" Text="Submit">
                        <DirectEvents>
                            <Click OnEvent="Button1_Click">
                            </Click>
                        </DirectEvents>
                    </ext:Button>
                </Items>
            </ext:FormPanel>
        </div>
        </form>
    </body>
    </html>
    
    My code behind code 
    
    protected void Button1_Click(object sender, DirectEventArgs e)
        {
            
            string chk = RadioGroup1.CheckedItems[0].BoxLabel.ToString();
            if (chk != null)
            {
                X.MessageBox.Alert("Click", chk).Show();
            }
            else
            {
                X.MessageBox.Alert("Click", "Select").Show();
            }
        }
