How to bind a Treeview to the database's External table data

 

This is an example of image favorites, which can store data recursively and hierarchically in Treeview infinitely.

 

Description of the main fields and meanings:

Name = node name (it may be the folder name or file name, which is determined by the dirflg field value)

Dirflg = whether node is a file [false] or a folder [True]

Parentid = index number of the parent item of Node

With these three key fields, you can accurately describe the node structure position in the Treeview in the program.
