You are a Web developer for an online research service ACME Research Inc. You are
creating an
ASP.NET application that will display research results to users of the ACME
Web site.
You use a DataGrid control to display a list of research
questions and the number of responses
received for each question. You want to modify the control so that the total number of
responses received is
displayed in the footer of the grid. You want to perform this task with the
minimum amount of development effort.
What should you do?

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.
