Sorting works very well for the first time , I loaded the grid. Then I do a clearAll() on the grid and I reload the grid with the new data. This time, when I click on the header to sort any column, sorting does not work correct. I see incorrect sorting
Basically the sorting always works with actual data and must not be affected by grid reloading.
If you are using filtering in same time , and older version of grid , it may be necessary to force filters clearing by
mygrid.clearAll();
//clear filtering buffers
mygrid._srowsCol=mygrid._srowsBuf=mygrid._f_rowsBuffer=null;
mygrid.loadXML("… //reloading grid
