)

The index within the posted collection that references the content to load.

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 Implementers:

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