Remarks
The ListViewDataItem class represents an individual data item in a ListView control. A data item usually corresponds to a record in a data source object. The class derives from the ListViewItem class.
Each item in the ListView control has a designated item type that is represented by the ItemType property. When the item type is ListViewItemType.DataItem, you can use the ListViewDataItem class to get more information about the item.
The ListView control stores data items in the Items collection. To determine the index of a ListViewDataItem object in the Items collection, use the DisplayIndex property. To determine the index of the data item in the underlying data source, use the DataItemIndex property. The difference between these index properties is that DisplayIndex represents the position of the data item in the current page, whereas DataItemIndex is based on the page offset. If the paging functionality is not enabled in the ListView control by using a DataPager control, these two properties will contain the same value.
You can access the properties of the underlying data object by using the DataItem property.
The DataItem property is available only during and after the ItemDataBound event of a ListView control.
For a list of initial property values for an instance of the ListViewDataItem class, see the ListViewDataItem constructor.
