Hi, I created a detailed ListView with two Columns, one of these columns is invisible. I do some changes on the values before I add them to the visible column. The original value was added into the hidden column. When I sort the visible column, I catch the Sorting Event and programmtically sort the hiddencolumn. Now there a two questions: 1st) How can I set the SortGlyph (the littel arrows) on the visible column manually, because after sorting by the hidden column there are not visible any more. 2nd) Is there a better way to do this work? I am not very happy with the hidden column. Thanks a lot!
