Setting the HasCheckBoxes property  to True causes the control to show a check-box for each displayed folder. User can check or uncheck those check-boxes at run time. The AfterCheck event notifies your application whether a folder is checked or unchecked. Use the PartialCheck property to enable partial check feature. This way, if a folder is checked, it's parent folder is partial checked, if it contains un-checked folders, or full checked, if all child folders are checked. Use the FoldersCheck property to get the collection of checked folders, at run-time.
