有没有办法检查表单中是否单击了任何单选按钮？

Question

I'm creating a form and I want the text of a button to change depending on if any radio button in the whole form has been clicked on, additionally some radio buttons are in group boxes so do not affect other radio buttons. The only way I can think of to do this is to input code into every method that is called for when each radio button is clicked. Is there any other way of doing it?

Answer 1

you can create one method for click event for one radioButton only and make all radioButtons share this click event and i will suppose that you will make Button text like radioButton text which you clicked and inside this method write this line...

private void radioButton1_Click(object sender,EventArgs e) {
    button1.Text = (RadioButton(sender)).Text;
}
