Chapter 13 - Last Try it Out
I'm having an issue on Chapter 13, I successfully completed the "Managing Data with the DetailsView Control" Try it Out, I can insert and update entries in my database without any issues.
When I complete the last Try it Out, "Customizing the DetailsView and Handling Its Events", both insert and update stop working. I get no error messages after clicking "Insert" or "Update", but when I go check the entries, they aren't there.
I also checked the databases physically on Web Developer's Database Explorer, no content seems to be added to my database.
I've deleted the AddEditReview page and restarted the Try it Outs and it's always the same result, first Try it Out works fine, second Try it Out - no dice. I've gone as far as compare your source with mine, and I can't seem to find any difference. Except that when I run your exercise it works...
Any idea what this could be? Thank you for your time.
