I have a page with a grid and when the datasource the grid is bound to has no rows, when the grid displays the filter boxes are not displayed. A checkbox on the page where the grid is displayed can be checked by the user which then creates a new datasource that does have rows based on a different search criteria and the grid redisplays but the filter boxes are not shown and thus the grid rows cannot be filtered. Is there a way to force the display of the filter boxes after the datasource is refreshed?
