How do you traverse through all radiobuttons on a form

ianparkins

Hi All, I have a bunch of radio buttons on my webform. What I do is only allow one to be checked at a time. But now I want to be able to tell which one is the one that is checked. Is there a way to do something like: foreach (Radiobutton r in this.Controls) { if (r.Checked == true) { ..... } } Obviously the above code doesn't work, but is there a way to do something like that. I don't know the syntax to do it. Please help if you can. Thanks, Zach(Nevermore)

Are you using an event function of the Radio Buttons? If so, try this as my example private void RadioButtonCheckEvent(object sender, System.EventArgs e) { RadioButton whichRButton = (RadioButton)sender; string message = whichRButton.Checked == true ? whichRButton.Text + "is checked" : ""; //to find which radio button on the form foreach(RadioButton r in this.Control) { if(r == whichRButton) { //do some code here } } } hope this will help

I think this should be valid foreach(Control ctrl in this.Controls) { if(Control is CheckBox) { if( ((CheckBox)ctrl).Checked ) { //do stuff } } }
