ItemDataBound Event

DataGrid.ItemDataBound Event

Occurs after an item is data bound to the DataGrid control.

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

JScript does not support events.
<asp:DataGrid OnItemDataBound="DataGridItemEventHandler" />

The ItemDataBound event is raised after an item is data bound to the DataGrid control. This event provides you with the last opportunity to access the data item before it is displayed on the client. After this event is raised, the data item is nulled out and no longer available.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to specify and code a handler for the ItemDataBound event to display the order that items in the DataGrid are data bounded.
