Based on following discussion:
It would be importand if we could get/set the sorting status of a column by code. Something like
TUniDBGris.colimns.SortingState; (ssNone, ssAsc, ssDesc)
Then we could save and reset the sort state of a grid.
At moment, if you open a form with a grid, you can not set the column shown as sorted which is actually sorted in the dataset behind. So, if the user clicks on the column header, nothing occurs but the header is shown as sorted, what it already was before..
