The class LoadItemsEventArgs object provides event data with information about how many items to load into the control on demand.

The following code example demonstrates how the OnLoadItems event calls the function LoadNow. The ItemIndex property determines the number of items to be added to an array that is bound to a list. In order to see the effects of this example, you must view the page on a device that can paginate the list.

NoteNote

The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information, see ASP.NET Web Page Code Model.
