I have this piece of VS C# code that have copied from my other programs and I know works. For some reason with this dataset it refuses to save the data. The grid appears on the screen, I change any value in the grid and then click a Save button, which I knows gets executed. When I look at the table, the values have not been changed. I need a fresh set of eyes to look at this. What am I missing? I have attached the code that displays the data and well as what is behind the Save button.
