Adding node to SAP PDK tree control dynamically

[Former Member]

Hello all,

I am using Tree control of the SAP PDK.NET and i want to add nodes as well as sub-nodes to that tree.

The data is coming from the web service and i want to assign that data to the tree nodes.

Can anybody helps me in?

Thanks in advance,

Prashant

Hi,

You can do it easily, use the following code as an exmple:

(just drop Button & Tree control first)

 protected void Page_Load(object sender, EventArgs e)
        {
            if (IsPostBack)
            {
                Tree1.RootNode = (TreeNode)Session["tree"];
            }
        }

        protected void Button1_Action(object sender, AbstractButton.ActionEventArgs e)
        {
            TreeNode node = new TreeNode(Tree1);
            node.Text = DateTime.Now.ToLongTimeString();
            Tree1.RootNode.Nodes.AddAt(Tree1.RootNode.Nodes.Count,node);
            Session["tree"] = Tree1.RootNode;
            
        }
