PagedControl.LoadItems Event


Occurs when a control is custom-paginated and needs more data. This API is obsolete. For information about how to develop ASP.NET mobile applications, see the Web site.

Namespace:   System.Web.UI.MobileControls
Assembly:  System.Web.Mobile (in System.Web.Mobile.dll)

public event LoadItemsEventHandler LoadItems

When control is custom-paginated, you do not explicitly bind the control. After pagination, the control raises this event, indicating what part of the data is required. The application can handle this event and bind the control with the required data.

The following example shows how to use the ItemsPerPage property to render eight items of a 200-item list per page.

<%@ Page Language="C#" 
    Inherits="System.Web.UI.MobileControls.MobilePage" %>
<%@ Register TagPrefix="mobile" 
    Assembly="System.Web.Mobile" %>

<script runat="server">
    // Called by the List whenever it needs new items
    private void LoadNow(object sender, LoadItemsEventArgs e)
        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

        // 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
        List1.DataSource = arr;

<html xmlns="" >
    <mobile:Form id="Form1" runat="server" Paginate="true">
        <mobile:List id="List1" runat="server" 
            ItemCount="200" onLoadItems="LoadNow" />
