Upgrading from demo to development

[Rod]

I recently purchased the full developer version of RadControls for ASP.NET AJAX and followed all the directions to get my site working with no avail.

I uninstalled the old version;
Installed the new one;
Updated references to new dll's;

Also, the RAD controls don't show up on the toolbox anymore.
I ran the Register utility again, but no luck.
I can manually create a tab and add them by pointing to the dll, but I get an error when I try to use them.

The error I'm getting on the page is

Could not load file or assembly 'Telerik.Web.UI, Version=2008.2.723.35

Thanks,

Rod Liberal

Hello Rod,

Could you check if there is registration in GAC?
Add/Remove RadControls to the Global Assembly Cache

Also you may search your web.config for strings containing "723".

Please let us know what your findings are.

Hi Daniel,

Thanks for your prompt reply (as you guys always do).

The GAC only contains Telerik.Charting, version 2.0.5.0

Here's what I found in the web.config:

<add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2008.2.723.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>

in the httpHandlers section.

What should I change that to?

Hello Rod,

Try to change your http handler as follows:

<add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Culture=neutral" validate="false"/>

Your Visual Studio should not be running during the installation/deinstallation. Additionally you can check for the presence of devenv.exe or aspnet_wp.exe processes in your Task Manager. More information is available in the following KB article:

Daniel,

I removed that line from the web.config and used the smart tag on a RAD control to add it back in and everything is working great now.

Unfortunately, the toolbox utility still does not add the controls to my toolbox.

Hi Rod,

You can find detailed explanation how to add the RadControls to the VS toolbox in the following online help resources (please, note that you should choose the one which matches the version of VS and .NET you are using):
