hi all,
i wanted to fill a TreeView control from a text files, where a text file holds a root and each root has another text file with the nodes or children of this root.

the problem is in adding the roots and nodes to the tree view, because it needs a "treeNode[]" array, and offcourse the array needs a constant which i dont know what it could be, and it doesnt allow null values in the array.
---so plz if u can offer any suggestion , go ahead :)

By constant, do you mean a length of array? You mean you have to set the size of the array as you create it?

Why not add the items individually?

[amrosama]

yes you are right, but i think this applies if the TreeView have only individual nodes without children.
im not sure if am right though, so please can you explain more or write samle code.
thnx for ur reply

If you want to add a node to a tree with children:

//Add the node.
//But keep a reference to it.
TreeNode node = tree.Nodes.Add("Lvl 1 node");
//Add a child node to the referenced object.
node.Nodes.Add("Lvl 2 node");

thnx lot xav you are a genius, its simple and easy
i would have probably given up:)

it worked with a small modification by using (node.Nodes .Add("level 2 node");
because there isnt a childnode class or method.

Whoops, sorry! I did mean Nodes, but I typed ChildNodes by accident, I got mixed up with XML. :)

I'm glad you got it going!
