RadControls Design time and Intellisense in Visual Studio 2010 Beta2

[Telerik Admin]

There is a limitation in Visual Studio 2010 Beta2 we identified recently: The design time of RadControls for ASP.NET AJAX is not working properly and the intellisense is broken in a standard setup (having the Telerik.Web.UI assembly in the website bin folder).

While we are working together with Microsoft for having this fixed, here are two workarounds:

1. You won't get the design time or the intellisense broken if you perform these two steps when closing your project in VS2010:

• Open a page, containing a RadControl in design mode (ignore the design mode errors);
• Close the IDE. The next load of the solution in Visual Studio 2010 should open the page in design mode again, but the designers should be loaded successfully and the intellisense should be working properly.

2. Add the Telerik.Web.UI assembly to the GAC or copy it to the [VisualStudioInstallDir]\Common7\IDE\PrivateAssemblies folder. The Visual Studio IDE would load the Telerik.Web.UI assembly properly.

Hi
I've done your  workarounds but the design time error still exists.

Thanks for the tip.

I had some limited success with the workaround. The RadGrid works at design-time now, but RadAjaxManager and RadAjaxPanel are broken and reporting "Unknown server tag'.

Hello guys,

I am happy to inform you that for the Q1 2010 release of RadControls for ASP.NET AJAX (expected in the beginning of March) we will provide a native .NET4 build of the controls against the current VS 2010 version by that time. We will also do our best to address any design-time issues we currently have with the VS 2010 Beta2 version.

Kind regards,
Sebastian

I am using the 2009 Q3 Release of the ASP.NET AJAX controls and have the tag prefix registered in the web.config file.  However, while using the RTM of VS 2010 the intellisense is not picking up on the tag prefix.  Did you have any progress on this issue with Microsoft?  I have also put the Telerik.Web.UI and Telerik.Web.UI.Design assemblies in the GAC and this still did not work.

Hi Ryan,

Yes, the problem was solved correctly in the RC version of the IDE and we verified intellisense works correctly with the RTM.

Basically the addition of the Telerik.Web.UI assembly to the GAC or to the [VisualStudioInstallDir]\Common7\IDE\PrivateAssemblies or [VisualStudioInstallDir]\Common7\IDE\PublicAssemblies folders should not be needed with VS2010 RTM.

Could it be that you have an older version of the Telerik.Web.UI assembly in the PublicAssemblies/PrivateAssemblies folders?

I was using the Q3 2009 version when I first experienced the issue, then I upgraded to Q1 2010 and was still having the issue.  I do have the telerik tagPrefix registered in the web.config, and the only way I was able to get it to work was using the registration below.

<system.web>
    <pages theme="Default">
        <controls>
            <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>
            <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.Design, Version=2010.1.415.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/>
            <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
