Hi,

Please use the TreePanel Checked Nodes property.

Example

Code:

<%@ 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> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Ext.NET v2 Example</title> </head> <body> <form runat="server"> <ext:ResourceManager runat="server" /> <ext:TreePanel ID="TreePanel1" runat="server" AutoHeight="true"> <Root> <ext:Node Text="Root" Expanded="true" Checked="false"> <Children> <ext:Node Text="Node1" Expanded="true" Checked="false"> <Children> <ext:Node Text="Node11" Expanded="true" Checked="false"> <Children> <ext:Node Text="Node11" Leaf="true" Checked="false" /> <ext:Node Text="Node112" Leaf="true" Checked="false" /> </Children> </ext:Node> </Children> </ext:Node> </Children> </ext:Node> </Root> </ext:TreePanel> <ext:Button runat="server" Text="Get checked nodes" OnDirectClick="GetChecked" /> </form> </body> </html>
