Sortable-Columns
When this style is set, tree-view columns become sortable. When the user clicks a column heading, the tree-view content is sorted by that column. No additional programming is needed because only the appearance is affected and the program still receives columns' information as if they were in their original positions.
The icons displayed on the heading can be customized by providing custom PNG files as described in
Default icons.
The sort logic depends on the
Sort-Types property.
This style has effect only in conjunction with the
Table-View style.
