Datagrid - Edit/Update Question

[Jennifer]

I've got a datagrid. I want to allow the user to edit in the grid
directly. I'm using ASP with VB as the code behind in Visual Studio
2002.

I've never had a need or desire to do this before, so I found an
Quickstart example at DotNetJunkies.com. I've modified it for my needs
and can't get it to work. Specifically, the part where I get the
edited cell values does not work. e.Item.Cells(1).Text returns
nothing. None of the other indexes returns anything either. Please
help me out.

Truly appreciated,
Jennifer
