Mono: Get value of the selected RadioButton [C#,gtk#]

FROM MONO DOCUMENTATION: @http://www.go-mono.com/docs/index.aspx?link=T%3AGtk.RadioButton

A single radio button performs the same basic function as a k.CheckButton, as its position in the object hierarchy reflects. It is only when multiple radio buttons are grouped together that they become a different user interface component in their own right.

Every radio button is a member of some group of radio buttons. When one is selected, all other radio buttons in the same group are deselected. A Gtk.RadioButton is one way of giving the user a choice from many options.

Radio button widgets are created with RadioButton(string), if this is the first radio button in a group. In subsequent calls, the group you wish to add this button to should be passed as an argument.

I found out that there exists not much examples about this issue so I post mine…

Code:


 using Gtk;
 using System;
 using System.Drawing;
namespace GtkSharpTutorial {

 class  FRM: Window
 {
 static GLib.SList group = null;
 private RadioButton radiobutton;
 private RadioButton radiobutton2;

 public  FRM()
 : base("deneme")
 {

 Application.Init();

 Window window = new Window("radio buttons");

 window.BorderWidth = 0;

 VBox box1 = new VBox (false, 0);
 window.Add(box1);
 box1.Show();

 VBox box2 = new VBox (false, 10);
 box2.BorderWidth = 10;
 box1.PackStart(box2, true, true, 0);
 box2.Show();

 radiobutton = new RadioButton  (null, "1");
 group = radiobutton.Group;
 radiobutton.Active = true;
 box2.PackStart(radiobutton, true, true, 0);
 radiobutton.Show();

 radiobutton2 = new RadioButton  (radiobutton, "2");
 box2.PackStart(radiobutton2, true, true, 0);
 radiobutton2.Show();
 radiobutton.Clicked+= new EventHandler(radiobutton_Clicked);
 radiobutton2.Clicked+= new EventHandler(radiobutton2_Clicked);
 window.ShowAll();

 }
 public static void Main()
 {
 Application.Init();
 new FRM();
 Application.Run();
 }

 void radiobutton2_Clicked(object sender, EventArgs e)
 {
 if(radiobutton2.Active==true){

 Console.WriteLine("2");
 }
 }

 void radiobutton_Clicked(object sender, EventArgs e)
 {
 if(radiobutton.Active==true){

 Console.WriteLine("1");
 }
 }

 }

}
<pre>

Output:
