Hi Mark,
Thanks for your followup.
As for the "GetNodeSrcFromDataBase()", it's just a dummy function I used to
get a url string(for the TreeNode's TreeNodeSrc ....). So you can write
your own helper function to retrieve the TreeNode src url string from
database or other storage....
Anyway, currently we could only programmatically assign TreeNodeSrc
property through code behind code. In addition, since the IE webcontrols
are legacy components which are no longer supported, we'd also recommend
you consider migrating to the new Naviagation controls in the ASP.NET
2.0(whidbey).
Thanks & Regards,
Steven Cheng

| Thanks Steven.
|
| You definitely understand my problem. What is the
| "GetNodeSrcFromDataBase()". Is that a command, a function I need to
build...?
| Also, it's not a big deal because I can translate fairly well, but I
write in
| VB.
|
| I really appreciate the help. In my research and simply trying to develop
| this, I've come across maybe a handful of articles even dealing with
| treenodes, and even fewer retrieving records from a database.
|
| Thank you,
|
