Post the code-behind in its entirety for Details.aspx.vb.

Also, read up on the Row_Updating and Rows_Updated functions. It took me some time to get a grasp on the difference between these two functions and im still sketchy on some instances. These two functions can cause alot of confusion.

Lastly, are you trying to update the gridview after posting new information into the database? or are you trying to Refresh the gridview to represent potentially new data that might have been updated in the database? What is your usage cause one of these two functions will be your solution, pending on how you intend to try and refresh your gridview.
