The ASP.NET page framework calls the RaisePostDataChangedEvent method on a RadioButtonList control when the LoadPostData method indicates that the state of the list items have changed in the RadioButtonList control. The RaisePostDataChangedEvent method calls the OnSelectedIndexChanged method to raise the SelectedIndexChanged event. Control developers can override the OnSelectedIndexChanged method to perform custom processing when the user changes the selected item in the control.
RaisePostBackEvent method can optionally perform validation before raising the SelectedIndexChanged event for the control. To validate a group of controls on the page when a list item within the RadioButtonList control is selected, set the AutoPostBack and CausesValidation properties to
true, and then specify the group of controls to be validated in the ValidationGroup property.
