=?iso-8859-1?Q?Jonathan_Hjertstr=F6m?=
Hi,

I am lost now. I really would like to make a tree view for a discussion =
forum. I can't get it to work. I want to add the nodes dynamically from =
my code behind.
I can get it down one level but I can't figure out how to append nodes =
down in the tree. Any help is greatly welcome!

I have tried looping through with this (I get my records from a Data =
Reader):

Dim xx As TreeNode =3D New TreeNode()
xx.Text =3D myDataReaderThread("Subject")
TreeView1.Nodes(i).Nodes.Add(xx)

I have seen this code that will do what I want but I can't figure out =
how to do it automatically because here the tree node is statically set.

Dim node2 As TreeNode =3D New TreeNode()
node2.Text =3D "first child"
node2.Expanded =3D True
Dim node3 As TreeNode =3D New TreeNode()
node3.Text =3D "second child"
node3.Expanded =3D True
node1.Nodes.Add(node2)
node1.Nodes.Add(node3)
Dim node4 As TreeNode =3D New TreeNode()
node4.Text =3D "first grand child"
node4.Expanded =3D True
Dim node5 As TreeNode =3D New TreeNode()
node5.Text =3D "second grand child"
node5.Expanded =3D True
node2.Nodes.Add(node4)
node3.Nodes.Add(node5)

This is how what my SQL query return:
I got the code from this site, =

Hi,

you can create treeview dynamically looping through Tree Collection =
node.
