Adding table values to a treeview

Question

I am using Vb 2008 express edition and am very new to treeviews. i have basic knowledge of how to connect to a database. the database i am working with is a microsoft access database and has a large amount of tables with various information. two of these tables i need to put into a treeview. one has 2 columns called date and date id, the date will be the main nodes on the treeview. the other table has 8 colums, among them are the corresponding date id's from the first table, the purchase order id and the purchase order number. the child nodes will be the purchase order number.

Now i know there are a bunch of tutorials out there on treeview population through microsoft access databases but i have found none specifically with what i need, they are all just about dumping ALL the data from the database into the table. i just want specific contents of two tables. if someone could help me out with this i would be very grateful. i can give more information if needed on what i am working with or anything else.!

This is an example of what it needs to look like. i am upgrading this program from vb6 to vb.net which is why i already have the program.

Answer 1

What you will have to do is loop through the first table (using sql and a datareader, for example) and then create the initial (parent) nodes. (Note that the below is a general idea, you will have to figure out the loop and datareader parts).

looping structure
    TreeView1.Nodes.Add(nodeName, nodeName)
next record

Then, loop through the second table, adding the record to the correct node...

looping structure
    TreeView1.Nodes(parentNodeName).Nodes.Add(nodeName, nodeName)
next record
