Trying to keep any filters in place if the grid data is reloaded via FillWithData

I'm using this code:

iGAutoFilterManager1.SaveFilterToMemory("CURRENTFILTER");
loadGrid(); //This routine calls FillWithData and sets grid properties
iGAutoFilterManager1.RestoreFilterFromMemory("CURRENTFILTER");

iGAutoFilterManager1.ReapplyFilter(); // Tried adding this as well

I didn't see a question. What happens? What version of iGrid is used?

We need a more detailed description of the problem and understand what the loadGrid() method does.
