Methods

	Name	Description
	Equals(Object)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Remarks

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.

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.

        // 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();
