Implements

IPostBackDataHandler::LoadPostData(String, NameValueCollection)

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

The ListBox::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.
