|SortOnClickEnum||A SortOnClickEnum expression that indicates the action that control takes when user clicks the column's header.|
There are two methods to get the items sorted like follows:
List1.Columns(ColIndex).SortOrder = SortAscending
The SortOrder property adds the sorting icon to the column's header, if the DisplaySortIcon property is True.
List1.Items.Sort "Column 1", False
The control fires the Sort event when the control sorts a column ( the user clicks the column's head ) or when the sorting position is changed in the control's sort bar. Use the Sort event to sort the data when the SortOnClk property is exUserSort
