Hey, According what you've said.I've successfully solved the problem.
Much appreciate it.

When opening the filter popup, the ListSourceRowIndex properties come through as -1, so you cannot obtain the value of invisible field used for sorting. How can the example be modified to work for both the grid and within the filter popup?
