Remarks

Typically, you should use the ListBox.LoadPostData method to process posted data for changes to a ListBox object.

The IPostBackDataHandler.LoadPostData method is an explicit interface member implementation. It can be used only when the ListBox instance is cast to an IPostBackDataHandler interface.

Notes to Inheritors

To define a custom implementation for processing posted data for a ListBox object, override the LoadPostData(String, NameValueCollection) member. The explicit interface implementation calls the LoadPostData(String, NameValueCollection) method to process the posted data for the control.
