We have a question regarding the NTreeList control. When the "Sorting" or "Grouping" feature is used, modifying the content of the list leads to inconsistent results.

If we call ClearAllNodes, and populate again the list, the column that was sorted is still marked with the up/down arrow in the header and the different color, but the content is not sorted.

If a column was defined as a grouping column, it disappears.

Is there a way to have the nodes still sorted/grouped according to the current sorting/grouping column?

Thank you in advance.

Best regards.
