All radiobuttons are checked c#

I have a problem with my 3 radiobuttons in c# at Visual Studio 2012 - when i run this application in browser and check first radiobutton, then check second the both of them are marked.

{
public partial class _Default : Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }


    protected void Button1_Click1(object sender, EventArgs e)
    {
        if (RadioButton1.Checked) 
        {
            ListBox1.Items.Add(TextBox1.Text);
            TextBox1.Text = "";             
        }
        else if (RadioButton2.Checked) 
        {
            ListBox2.Items.Add(TextBox1.Text);
            TextBox1.Text = "";
        }
        else if (RadioButton3.Checked) 
        {
            ListBox3.Items.Add(TextBox1.Text);             
            TextBox1.Text = "";
        }
    }

    protected void Button2_Click(object sender, EventArgs e)
    {
        {
            ListBox1.Items.Clear();
            ListBox2.Items.Clear();
            ListBox3.Items.Clear();
        }
    }
    }
}

Make sure you set the GroupName attribute of the radiobuttons to the same value ( a name for that group of radio buttons).

eg:

<asp:RadioButton id="Radio1" Text="something" GroupName="RadioGroup1" runat="server" />
<asp:RadioButton id="Radio2" Text="another thing" GroupName="RadioGroup1" runat="server" />
<asp:RadioButton id="Radio3" Text="something else" GroupName="RadioGroup1" runat="server" />
