The only way to speed up building a treeview is to build it dynamically. For instance, you don't need to load the children nodes if you are starting out with everything collapsed. Then, when something is expanded, go back to access and get the children and fill them in.

You may have a slight delay when opening a node, but not like loading everything all at once...especially since with 7,000,000 records, the likelihood of anyone looking at all of them is probably around 0%.

It may depend on the speed (method) of data reading... :)
