Create an editable treeview control in execution of the xml document (part 5)

Running treeview control
For perfection, list 4 contains the final treevie control of VB. NET version and or C # version. To make it easier to use, I have redefined the structure and code. The KeyDown Control is added to support some default shortcut keys, such as Control-N (new), F2 (edit), and DEL (delete ).
It seems that there is no need to attach any event, so the final api contains a method and eight attributes. They are listed in Table 1. Most of them are simple signs or default switches, I added them so that you can choose to use them to enhance the editable features of your application.

Table 1: Attributes and methods of the xmltreeview control. You can use them in your application.
