Hello again, I see that if I change the gridview's viewstate property to true, it work, but I see that I update a row on the gridview, press save on the form (to save the bO) and the record don't change, I have to handle the event RowUpdated and set manually each row on the BO?



thanks!

Changing the viewstate property on the grid will cause it to save its data source to the viewstate (the business object), so when the grid is updated, the proper instance of the business object is not updated (the one from the viewstate, not the one from the form).  So, no, you don't have to manually handle the UpdateRow event; it is handled internally to copy the data back to the business object.  However, I am not sure why the Customers business object could not be located.  Let me test a few things here and see if I can find a solution for you.

Hi,

I had the exact same problem with the sample ... did you find a solution to the missing Customer Object Issue.

Are you running the C# or VB.NET sample?  Also, did you get the same from the forum or the install (http://forum.strataframe.net/FindPost12344.aspx) ?
