Initialize two radio buttons:'Yes' & 'No' in the windows form:

private System.Windows.Forms.RadioButton rdbtnYes;

private System.Windows.Forms.RadioButton rdbtnNo;

 

Next when you double click on either of two radio buttons you will see the below code will appear in vs 2003 editor:

private void rdbtnYes_CheckedChanged(object sender, EventArgs e)

{

if( rdbtnYes.Checked == true)

{

MessageBox.Show("Yes"); // Will show if you check the "Yes" radio button

}

}

private void rdbtnNo_CheckedChanged(object sender, EventArgs e)

{

if( rdbtnNo.Checked == true)

{

MessageBox.Show("No"); // Will show if you check the "No" radio button

}

}

 

that's all.happy coding
