You should create your data source once (on the user's first visit) and store it into Session for later use, and only bind the Grid View to the data source when it is necessary to do so.
I would recommend trying this out and starting a new thread in the .
If you do this, your Grid View's source will be refreshed before you're able to grab the new values out of it.
I'm having a very hard time understand what would prevent your event from being fired.
I put a breakpoint on the Row Updating event handler and found that the event is not fired. I put a breakpoint on the Row Updating event handler and found that the event is not fired. In the Row Editing function, the edit textboxes appear and I can get the "old" values Then the page renders, I edit the textboxes and hit Update.
Right now, I have not written code for the Update event. Right now, I have not written code for the Update event. Then the page posts back, the text boxes go back to being labels and the new values are lost, and the Row Updating code never fires.

So, here is some sample code that I use, and maybe it will help you: This goes in your Row Updating event Dim cell As Data Control Field Cell = Nothing 'This type will change if you are using Bound Fields 'The collection(s) have to be populated for EACH cell. You can also manipulate the Keys, Old Values, and New Values collections, if necessary, before the values are passed to the data source.A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source.
