Working with WebDataGrid 12.1 (Version=12.1.20121.1005). Have loaded GRID with BatchUpdating="True" and installed a "Save Changes" button.  WebDataGrid is bound to a SqlDataSource control.

Data is retrieved successfully.  When I change one or more rows on the grid and click the "Save Changes' button the values are saved on the grid.  However, when I check the data in the database the rows I changed in the grid are not reflected in the table; the data is unchanged.  When I click the "Save Changes" button a second time it triggers a postback and the data from the table table is loaded in the grid overwriting the changes I made previously.
