Remarks

The LoadPostData method is used primarily by control developers in custom controls that derive from the RadioButtonList class.

The LoadPostData method indicates whether the state of the RadioButtonList control has changed. In other words, it determines whether the selected list item in the control is the same as the last posted value. A user changing the selected item in the control changes the SelectedIndex value for the RadioButtonList control. If the same list item is selected in the control, or if the RadioButtonList control is disabled, LoadPostData returns false.

When the LoadPostData method returns true for a control, the ASP.NET page framework invokes the RaisePostDataChangedEvent method for the control.
