Hi:
     When using the NTreeList control, I add NTreeListNode with subitems, I set the column's sortable to be false. But it can still sort?
could you please show me how to set it to NotSortble.
    Here is my code:
    NTreeListColumn col;
    col = new NTreeListColumn();
    col.Name = "Project";
    col.Header.Text = "Project";
    col.Sortable = false;
   
    m_List.Columns.Add(col);
