HtmlInputRadioButton::Checked Property

Gets or sets a value indicating whether the HtmlInputRadioButton control is selected.

Namespace:  System.Web.UI.HtmlControls
Assembly:  System.Web (in System.Web.dll)

public:
property bool Checked {
	bool get ();
	void set (bool value);
}
<asp:HtmlInputRadioButton Checked="True|False" />

Property Value

Type: System::Boolean
true if the HtmlInputRadioButton control is selected; otherwise, false.

Use the Checked property to determine whether the HtmlInputRadioButton control is selected. If you have a group of HtmlInputRadioButton controls, you must iterate through the controls and test the Checked property of each control individually. You can also use this property to programmatically specify whether the control is selected.

You can group HtmlInputRadioButton controls together by specifying a common value for the Name property of each radio button control you want to include in the group.

NoteNote:

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 Checked property to determine which radio button in the group is selected.
