Property Value

Type: System.String

The group of check box controls that the instance of the HtmlInputRadioButton class is a member of.

Group multiple HtmlInputRadioButton controls by specifying a common value for the Name property of each radio button you want to include in the group. When you group HtmlInputRadioButton controls, only one radio button in the group can be selected at a time. The Checked property of the selected control is set to true, while the same property is set to false for all other radio buttons in the group.

The following code example demonstrates how to use the Name property to group multiple HtmlInputRadioButton controls.
