If this can't be done, is there a way to have a button or modify the existing select all so that it “selects” every item in the grid, or at least sends a call to a server URL that “all data results” are “selected”?
I think I can get around this with a custom pager button myself. I will require the user to filter their grid results accordingly and then click a button that will 'assume' they want all the records affected based on the current grid filters/results and perform my action based on that.
