I have an ASP.NET 3.5 GridView on a WebForm.
The GridView gets data from an ObjectDataSource which is set via the DataSourceID property in the code in front.
The ObjectDataSource returns a List of custom data class objects (just a class with public properties) to populate the GridView.
What I want to do is use the a List comsumed by the GridView in another code-behind method. At a high level:
1. GridView is loaded with List data from ObjectDataSource.
2. In the GridView.OnDataBound method I call GridView.DataSource to get the List object.
3. I enumerate the List and use the same data to do some other operation.
The theory being one less duplicated method call and one less call to the back-end database.
I've tried calling DataSource from the GridView' DataBound method and calling GridView.Rows[x].DataItem. In each case I only get a Null reference exception ("Object reference not set to an instance of an object").
Is there any way to achieve what I'm after?

If I understand you correctly, you want the
OnRowDataBound
event. This way, you can use data from the row that was just databound:
