Comments

The CheckBox property defines the file/folder's checkbox status.

Any checkbox can be clicked by the user, including disabled checkboxes. The CheckBoxClicked event occurs for all checkbox states.

Checkboxes are only displayed if the ShowCheckBoxes property is suitably defined.

The SetSubFolderCheckBoxes method can be used to update the checkboxes of all subfolders.

The folder's EvaluateSubFolderCheckBoxes method can be used to update its checkbox status based on its subfolders' checkboxes.
