I am asked to make a datagridview that shows the hierarchy of tables from parents>sub-parents>child.
I don't know how to put up a picture here so to give you a clear view of what I want to make is, imagine an ms access database with 3 tables named "Parent","Sub-parent" and "child". "Parent" is in the top of the hierarchy, connected to "Sub-Parent" with a foreign key. While the "Sub-Parent" table connected to the "Child" table, the same way "Sub-Parent" is connected to "Parent" table.
In the access, when you looked at the "Parent" table, you will be able to drop-down it to see the "Sub-Parent" data row until the "Child" data row whenever it corresponds with the primary key.
You see, I want to recreate that into visual basic style. I saw some downloadable treeview sample progs here but it is too advanced for me to study and uses some css/wpf thing that I don't have a single clue about.
