DataList.Items Property

Gets a collection of DataListItem objects representing the individual items within the control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public virtual DataListItemCollection Items { get; }
/** @property */
public DataListItemCollection get_Items ()

public function get Items () : DataListItemCollection

Property Value

A DataListItemCollection that contains a collection of DataListItem objects representing the individual items within the DataList control.

Use the Items collection to programmatically control the items in the DataList control. The Items collection does not provide any methods to add or remove items to the collection. However, you can control the contents of an item by providing a handler for the ItemCreated event.

NoteNote

Only items bound to the data source are contained in the Items collection. The header, footer, and separator are not included in the collection.

The following code example demonstrates how to use the Items collection to display the items in the DataList control.

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 on the Web Forms code model, see ASP.NET Web Page Code Model.
