Examples
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.
Note
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 Forms Page Code Model.

{
int j = e.ItemIndex;
int estItemSize = 110;
// Get the optimum page weight for the device
int wt = Form1.Adapter.Page.Adapter.OptimumPageWeight;
// Get the number of items per page
List1.ItemsPerPage = wt / estItemSize;
// Clear the current items
List1.Items.Clear();
// Build a section of the array
ArrayList arr= new ArrayList();
for (int i = 1; i <= e.ItemCount; i++)
{
int v = i + j;
arr.Add((v.ToString() + " List Item"));
}
// Assign the array to the list
