HtmlInputRadioButton::ServerChange Event

 

Occurs when the value of the Checked property of the HtmlInputRadioButton control changes between posts to the server.

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

public:
event EventHandler^ ServerChange {
	void add(EventHandler^ value);
	void remove(EventHandler^ value);
}

The ServerChange event is raised when the Checked property of the HtmlInputRadioButton control changes value between posts to the server. This allows you to create a custom event handler that performs a specific set of instructions (such as data validation) when the event is raised.

System_CAPS_noteNote

The control must have view state enabled for the ServerChange event to work correctly. To enable view state for all controls on the Web Forms page, set the Page::EnableViewState property to true. You can also enable view state for an individual control by setting the Control::EnableViewState property to true.

For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates how to specify and code a handler for the ServerChange event. The custom event handler updates a label on the Web page to display the value of the selected radio button.
