Failed to create designer error

Hi,

I am new to RAD controls. I have VS 2008, .NET 3.5 and installed the trial version of Telerik RAD controls for ASPNET AJAX Q1 2009. Per the Help documents I created a new .NET/C# Web project, added Script Manager to the default web page and trying to add RAD Tree View control. I am getting this error message:

Error Creating Control - RadTreeView1

Failed to create designer 'Telerik.Web.UI.RadTreeView, Telerik.Web.UI, Version=2009.1.402.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4'

I have added references to Telerik.Web.UI.dll and Telerik.Web.Design.dll

Am I missing something? Please help. Thanx.

Cannot create folder

Geting the error: "The selected folder could not be created because the application did not have enough permissions. Please contact the administrator"

This happens when I call createNewDirectory. I have looked around the forums for a soultion but nothing seems to work. How can I troubleshoot this. It doesn't seem to be permissions from what I have checked.

I tried this and it worked fine, meaning the code Fiko asks to run works fone:

http://www.telerik.com/community/forums/aspnet-ajax/file-explorer/cannot-create-folder-can-do-everything-else.aspx

Here is my simple test code, and I have full access on the server and the account used also has full permissions. I have used sysinternals procmon anbd I do not even see a denial of access, how can I trouble shoot this:

GridAttachmentColumn: File Upload Button Works Local, Not Remote

Hi,

I have a RadGrid with a GridAttachmentColumn. I created a test page and everything is working fine locally.

When I publish to a remote server, everything appears ok (attachments are retrieved, displayed and downloadable) but when I click "Add New Record" and click the file upload browse button, nothing happens. No script or server error, no UI response, nothing.

What can be going wrong?

Here's some code showing what I have. It works fine debugging using VS2010 built-in web server. I've necessarilly had to cut some of the code out.
