Populating treeview

Hi all,

I have a dataset that contains following records:

id ref_id level
--------------------------------------
A - 0
A1 A 1
A2 A 1
A3 A 1
A11 A1 2
A12 A1 2
A21 A2 2
A31 A3 2
A211 A21 3

The column 'ref_id' is supposed to be the parent/referrer of column 'id'
That means:
A refers A1,A2 and A3
A1 refers A11,A12
and so on.

What I want to achieve is to present the above dataset using a treeview in
an ASP.NET 2.0 (VB) page, so it will displays like this:

[+] A
[+] A1
A11
A12
[+] A2
[+] A21
A211
[+] A3
A31

Can somebody please show me how to do this?

Many thanks in advance,
Mike

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
