Hi. Sorry, I'm just a bit nerd using this controls.
What I'm trying to do is quite simple: I want to display treeview with some nodes linked to PDF files. Whe you click on that node, I want the PDF to open in a new Window. I populate the tree with data from a Database using the Adjacency List Model. In the event RadTreeView1_NodeDataBound, I set the NavigateUrl property of the node this way:

e.Node.NavigateUrl = "javascript:window.open('" + PDFpath + "')"

where PDFpath is a valid URL to the PDF I want to show in a new window. It work's fine (the PDF is opened in a new window), but the treeView displayed on the main page vanished, and show the word : "[object]". What I'm doing wrong?.

The code I'm using on the ASP page is quite simple, as you can see:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestWeb._Default" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

<!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></title>

<style type="text/css">

.style1

{

width: 100%;

}

.style2

{

width: 271px;

}

</style>

</head>

<body>

<form id="form1" runat="server">

<%-- <telerik:RadFormDecorator ID="RadFormDecorator1" Runat="server" DecoratedControls="Fieldset" />--%>

<asp:ScriptManager ID="ScriptManager1" runat="server" />

<div>

<table class="style1">

<tr><td colspan ="2">

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="llenar TreeView" />

<asp:Button ID="Button2" runat="server" onclick="Button2_Click"Text="Expediente 1" />

</td>

</tr>

<tr>

<td class="style2" valign="top">

<fieldset >

<telerik:RadTreeView ID="RadTreeView1" Runat="server"

LoadingMessage="Cargando ..." Skin="Outlook"

onnodedatabound="RadTreeView1_NodeDataBound" />

</fieldset>

</td>

<td>

<asp:GridView ID="GridView1" runat="server">

</asp:GridView>

</td>

</tr>

</table>

</div>

</form>

</body>

</html>

Thank's in advance

Hello Julio Loizaga,

Could you, please, try the following:
- set the navigate url without the "javascript:window.open" part, just the clean url. Then set a target attribute to the link element of the node with the value of "_blank".

Please, let me know the results.
I hope this will solve it for you!
