Hi Kevin,
I'm getting the following error in the web forms example, in the Update button handler method of the OrderDetails DataGrid. It happens on the save() function. I've stepped through lots of code in the debugger, but can't figure it out. I've verified that the ItemIndex is being set correctly. Hope I didn't do something stupid.. Any ideas? TIA. Mark

Server Error in '/Order System Web CSharp' Application.
