Problems in communication between a Tree Panel and a Grid Panel

[joao]

Hi,

I created a class that extends from Ext.Net.Container, and in that class I create 2 Ext.Net Controls, 1 Tree Panel and 1 Grid Panel. And my objective is when you click on a Tree Node gets its id and fill the Grid, I already tried various ways to get there, but all unsuccessful.

First, I tried to attach to every TreeNode a call to a DirectMethod, and placed the DirectMethod in the class that I created, but when you run the container he doesn't find the DirectMethod, I tried also to change the DirectMethod's Namespace, but he didnt find the Namespace.

------------------------ CODE: ---------------------------
private Ext.Net.TreePanel tp = new Ext.Net.TreePanel();
private Ext.Net.GridPanel gp = new Ext.Net.GridPanel();

        public ExplorerView() : base()
        {
            Ext.Net.TreeNode root = new Ext.Net.TreeNode("rootNode" + this.DynamicID, "Test", Ext.Net.Icon.Folder);

            tp.ID = "gridID";
            tp.Root.Add(root);

            Ext.Net.TreeNode nodeChild = new Ext.Net.TreeNode("node" + id, name, Ext.Net.Icon.Folder);
            nodeChild.Listeners.Click.Handler = "Ext.net.DirectMethods.TreeNode_Click()";
            root.Nodes.Add(nodeChild);
        }

        [DirectMethod]
        public void TreeNode_Click()
        {
            // do action
        }
OR
            nodeChild.Listeners.Click.Handler = "Test.TreeNode_Click()";

        [DirectMethod (Namespace="Test")]
        protected void TreeNode_Click()
        {
            // do action
        }

Then I tried with DirectEvents on the TreePanel, but I have problems with the TreePanel.ID, if I don't "identify" the TreePanel, doesnt show anything, gives a javascript: sintax error.
If I give a tp.ID = Dynamic.ID, whenever I click a node he changes the tp.ID.

------------------------ CODE: ---------------------------

            tp.DirectEvents.Click.Event += new Ext.Net.ComponentDirectEvent.DirectEventHandler(TreeNode_Click);
            tp.DirectEvents.Click.ExtraParams.Add(new Ext.Net.Parameter("id", this.tp.ID + ".getSelectionModel().getSelectedNode().id", ParameterMode.Raw));


If I give a tp.ID = 'gridID' it calls TreeNode_Click(), but it doesnt update the GridPanel and I would like to create more than one instance of this container.

------------------------ CODE: ---------------------------
public void TreeNode_Click()
        {
            JsonReader reader = new JsonReader();
            reader.IDProperty = "idjsonreader1";
            reader.Fields.Add(new RecordField("id"));
            reader.Fields.Add(new RecordField("name"));

            Ext.Net.Store store = new Ext.Net.Store();
            store.Reader.Add(reader);
            store.ID = "storeID";

            DataTable dt = new DataTable();
            dt.Columns.Add("id");
            dt.Columns.Add("name");
            DataRow dr = dt.NewRow();
            dr[0] = 1;
            dr[1] = "Lisbon";
            dt.Rows.Add(dr);

            DataSet ds = new DataSet();
            ds.Tables.Add(dt);

            store.DataSource = ds;
            store.DataBind();
            this.gp.Store.RemoveAt(0);
            this.gp.Store.Add(store);
            this.gp.Reconfigure();
            this.gp.Reload();
        }

Questions:

Could you help me find a way that I can have a DynamicID TreePanel or a way to use DirectMethods associated to the TreeNodes in the same class?
