            Ext.each(selChildren, function (node) {
                if (msg.length > 0) {
                    msg += ", ";
                }

    Hi,

    Please use the TreePanel Checked Nodes property.

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

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

<script runat="server">
    protected void GetChecked(object sender, DirectEventArgs e)
    {
        StringBuilder s = new StringBuilder();

        if (this.TreePanel1.CheckedNodes != null)
        {
            foreach (SubmittedNode node in this.TreePanel1.CheckedNodes)
            {
                s.AppendFormat("{0}<br/>", node.Text);
            }
        }
        else
        {
            s.Append("No checked nodes");
        }
        
        X.Msg.Alert("Checked", s).Show();
    }
</script>
