Hi

I have created a tree view (see code section)

In which there is a root element called "$".

Now I want add nodes in this root column programatically. How can I do that in vb.net

<asp:TreeView ID = "tvMain" ExpandDepth = "0" PopulateNodesFromClient = "true" ShowLines = "true" 
                            ShowExpandCollapse = "true" runat = "server" CollapseImageUrl = "~/images/Folder.JPG" 
                            ExpandImageUrl = "~/images/FolderExpanded.JPG">
                            <Nodes>
                                 <asp:TreeNode Text="$" ImageUrl = "~/images/Folder.JPG">
                                     <asp:TreeNode Text="$" ImageUrl = "~/images/Folder.JPG">                                 
                                    </asp:TreeNode>
                                </asp:TreeNode>
                            </Nodes>
                        </asp:TreeView>
