안녕하세요 ^^.

간단한 예제 소스 입니다.

어렵지 않을꺼에요.

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Tree_Click(object sender, DirectEventArgs e)
    {
        string id = e.ExtraParams["id"] ?? "";

        X.Msg.Alert("Node Id", "id = " + id).Show();
    }
</script>


<!DOCTYPE html>

<html>
<head id="Head1" runat="server">
    <title>Good Luck !! Friend</title>
</head>
    <body>
        <form id="Form1" runat="server">
            <ext:ResourceManager ID="ResourceManager1" runat="server" />

            <ext:TreePanel ID="TreePanel1" runat="server" Title="Catalog" Width="300" Height="450">            
                <Root>
                    <ext:Node Text="Composers" Expanded="true">
                        <Children>
                            <ext:Node NodeID="Node1" Text="No.1" Leaf="true" />
                            <ext:Node NodeID="Node2" Text="No.2" Leaf="true" />
                            <ext:Node NodeID="Node3" Text="No.3" Leaf="true" />
                            <ext:Node NodeID="Node4" Text="No.4" Leaf="true" />
                            <ext:Node NodeID="Node5" Text="No.5" Leaf="true" />
                        </Children>
                    </ext:Node>
                </Root>

                <DirectEvents>
                    <ItemClick OnEvent="Tree_Click" Before="if(!record.data.leaf){return false;};">
                        <ExtraParams>
                            <ext:Parameter Name="id" Value="record.data.id" Mode="Raw"/>
                        </ExtraParams>
                    </ItemClick>
                </DirectEvents>
            </ext:TreePanel>
        </form>
    </body>
</html>

간단하게 만들어 보았어요.

도움이 되면 좋겠네요.
