                TreeNode Tnode = new TreeNode("ParentNode");


Hey there,

First of all, in order to add a new PARENT node at runtime you should use this code:

TreeNode parent = new Node;

for a CHILD node:

TreeNode child = new Node;

Now, what has to do with the Data show, then you need to load all the data that you want in a collection(DataTable,List) and then create a recursive function in order to create the treeview structure on all depths.

Hope i helped. :)

i have database witht these column names id,nodename,nodelevel.
in this i have to add the value to the ultratree from database as parentnode and childnode. for example(state)is a parentnde ,its childnode as (tamilnadu)and(kerala).tamilnadu's childnode as(chennai) and( pondcherry) etc for this i want a ultratree to dispay it
