I have a master-detail page with gridview containing the master records and a formview showing the detail of the record that the user selects in the gridview. Both controls are bound using the objectdatasource. In the formview I have a button that calls a function that does some processing including updating a field in the data that's displayed in formview. The problem is when the button is clicked and processing completed that data displayed in formview is not updating. If I navigate away from the page and then go back to it the data is updated. How do I get the formview to update the data properly?
