A System.Object that represents a data item in the DataGrid control.

Use the DataItem property to specify or determine the properties of a data item represented by the DataGridItem object in the DataGrid control.


This property applies only to data items in the DataGrid control. The ItemType property must be set to ListItemType.Item, ListItemType.AlternatingItem, ListItemType.SelectedItem, or ListItemType.EditItem.

The following code example demonstrates how to use the DataItem property to display the contents of the data items in the DataGrid control.
