Dropdown list with folder tree.
For a list of all members of this class, see ShellComboBox Members.
This control/applet enables the user to select a folder in the ImageUploader by choosing it in the dropdown list. To connect ImageUploader with ShellComboBox, you should put both controls on the same page and specify a name of the ImageUploader control instance as a value of the ParentControlName property of the ShellComboBox. It will cause these controls to be automatically mutually synchronized.
