Hi
I have installed RadControls for ASP.NET AJAX Q3 2009 and also addred reference to the project solution 'Telerik.Web.UI.dll' version 2009.3.1314.35. I can see my controls in design view. I can build and debug the solution to run it fiine.

In the source code ,while I type <te I should be viewing the drop down to list Telerik controls,which I cant view.
Also I get the following warning.

Element 'RadAjaxLoadingPanel' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.

I have my solution in C:\Data\VS8\Source Code\StaffNet. My web.config file is in the right place.

Can you please suggest?

Thank you in advance.

Hi Sucheta,

The problem could occur if the files are on a shared network location. Does the Bin folder and the Telerik assembly resides locally on your machine?

Additionally, could you please make sure that your web.config is set up to use ASP.NET AJAX?

Hi
There are no files on shared network location. I am working on my local machine with bin35 and telerik assembly on it.
I have also checked for the web.config file which is set up to use ASP.NET AJAX.

I had earlier                             RadControls_for_ASP.NET_AJAX_2009_3_1208_dev             installed
and then I downloaded            RadControls_for_ASP.NET_AJAX_2009_3_1314_dev


After which the warning started coming up.
I had to download the latest RadControls_for_ASP.NET_AJAX_2009_3_1314_dev cause I couldnt see the controls in design view and used to get 'Error Rendering Control' error. I also added the Telerik.Web.UI.dll  version 35 in Assembly Cache to get it working.

Now I keep getting these warnings and not easy to work while coding as I cant see the properties of the controls in source view.
Help!!
