I have a page with a RadFileExplorer with EnableAsyncUpload to true.

When I drag and drop a document and upload this document I get to following error : Unable to get property 'add_folderLoaded' of undefined or null reference.

My page :

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

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

<%@ Register TagPrefix="asp" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit"%>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<meta content="C#" name="CODE_LANGUAGE"/>

<meta http-equiv="X-UA-Compatible" content="IE=edgde,chrome=1" />

</head>

<body>

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

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"></asp:ToolkitScriptManager>

<telerik:RadFileExplorer runat="server" ID="FileExplorer1" Width="520px" Height="500px" AllowPaging="true" PageSize="10" ExplorerMode="FileTree" >

<Configuration EnableAsyncUpload="true" ></Configuration>

</telerik:RadFileExplorer>

</form>

</body>

</html>

The folders are set in code behind :

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

String FolderRoot = @"~/DataFolder/ITServiceTickets/1142957/";

string[] Paths = new string[]

{

@FolderRoot

};

FileExplorer1.Configuration.ViewPaths = Paths;

FileExplorer1.Configuration.UploadPaths = Paths;

FileExplorer1.Configuration.DeletePaths = Paths;

}

What is the problem?

Kind regards

Suzy

Hi Vessy,

I tried it with following code, still the same problem :

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="FileExplorerWithoutHomePage.aspx.cs" Inherits="cmWeb.Test.FileExplorerWithoutHomePage" %>
