NameDescription
System_CAPS_pubmethodLoadItemsEventArgs(Int32, Int32)

Initializes a new instance of the LoadItemsEventArgs class. This API is obsolete. For information about how to develop ASP.NET mobile applications, see the www.asp.net/mobile Web site.

NameDescription
System_CAPS_pubpropertyItemCount

Gets or sets the count of items in the control. This API is obsolete. For information about how to develop ASP.NET mobile applications, see the www.asp.net/mobile Web site.

System_CAPS_pubpropertyItemIndex

Gets the index of the first item to be loaded by the invoked event. This API is obsolete. For information about how to develop ASP.NET mobile applications, see the www.asp.net/mobile Web site.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

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.

        // 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
        List1.DataSource = arr;
        List1.DataBind();
    }
