Question

public HtmlGenericControl fieldset = new HtmlGenericControl("fieldset");
public HtmlGenericControl legend = new HtmlGenericControl("legend");

String[] options = ListString.Split(',');
for (int i = 0; i < options.Length; i++)
{
    RadioButton aRadioButton = new RadioButton();
    aRadioButton.Text = options[i];
    fieldset.Controls.Add(aRadioButton);
}

fieldset.Controls.add(legend)

Yet when the radio list appears on my page, multiple radio buttons are selectable. How do I restrict the selection limit to 1?

Answer 1

Try this:

aRadioButton.GroupName = "myGroup";

Each RadioButton must be in a group so that it knows when to deselect the others from the same group.
