[CLOSED] Append a fully loaded child in a remote TreePanel

[RCN]

Hi folks, i have a TreePanel that uses an AjaxProxy to perform the load of child nodes. It works perfectly but i have a scenario that i need to append a "fully" loaded node.

In the example bellow when the _btnAppendSubTree Button is clicked a node with three levels is loaded. but when i expand the it, the load of sub-items is performed, but i just want to show the item previously loaded.

In version 1.x of Ext.Net i could set whether nodes were async by instantiate it as Node or AsyncNode. Is there any way to inform that the node is not async?

1 - View

<ext:ResourceManager ID="ResourceManager1" runat="server" />
<ext:Button ID="_btnAppendSubTree" runat="server" Text="Append Sub Tree">
    <Listeners>
        <Click Handler="AppendSubTree();" />
    </Listeners>
</ext:Button>
<ext:TreePanel ID="TreePanel1" runat="server" Icon="Accept" Height="300" Shadow="false"
    UseArrows="true" AutoScroll="true" Animate="true" EnableDD="true" RootVisible="false">
    <Fields>
        <ext:ModelField Name="Task" />
    </Fields>
    <ColumnModel>
        <Columns>
            <ext:TreeColumn ID="TreeColumn2" runat="server" Text="Task" DataIndex="Task" />
        </Columns>
    </ColumnModel>
    <Store>
        <ext:TreeStore ID="TreeStore1" NodeParam="nodeId" AutoLoad="true" runat="server">
            <Proxy>
                <ext:AjaxProxy Url="/Example/loadNodeChildren/">
                    <Reader>
                        <ext:JsonReader Root="data" />
                    </Reader>
                </ext:AjaxProxy>
            </Proxy>
        </ext:TreeStore>
    </Store>
    <Root>
        <ext:Node NodeID="0" Text="Tasks" />
    </Root>
</ext:TreePanel>

2 - JavaScript

var AppendSubTree = function () {
    Ext.net.DirectMethod.request({
        url: "/Example/AppendSubTree",
        cleanRequest: true,
        success: function (result) {
            App.TreePanel1.getRootNode().appendChild(Ext.decode(result.data));
        }
    });
}

3 - Controller

public StoreResult loadNodeChildren(string nodeId)
{
    NodeCollection nodes = new NodeCollection(false);

    if (!string.IsNullOrEmpty(nodeId))
    {
        for (int indice = 1; indice < 6; indice++)
        {
            Node no = new Node();
            no.NodeID = nodeId + indice;
            no.CustomAttributes.Add(new ConfigItem { Name = "Task", Value = no.NodeID, Mode = ParameterMode.Value });
            nodes.Add(no);
        }
    }

    return new StoreResult { Data = nodes.ToJson() };
}

public StoreResult AppendSubTree(string nodeId)
{
    NodeCollection nodes = new NodeCollection(false);

    Node no = new Node();
    no.NodeID = "sub0";
    no.CustomAttributes.Add(new ConfigItem { Name = "Task", Value = no.NodeID, Mode = ParameterMode.Value });

    nodes.Add(no);

    Node subNode1 = new Node();
    subNode1.NodeID = "sub1";
    subNode1.CustomAttributes.Add(new ConfigItem { Name = "Task", Value = subNode1.NodeID, Mode = ParameterMode.Value });
    no.Children.Add(subNode1);

    Node subNode2 = new Node();
    subNode2.NodeID = no.NodeID + "sub2";
    subNode2.CustomAttributes.Add(new ConfigItem { Name = "Task", Value = subNode2.NodeID, Mode = ParameterMode.Value });
    subNode1.Children.Add(subNode2);

    return new StoreResult { Data = nodes.ToJson() };
}
