    I installed the .NET Telerik controls (AJAX) and the extensions for VS 2013 and I want to generate a web application targeting .NET 4.

    If I target .NET 4.5.1, then the tools appear in the toolbox but if I target .NET 4 then they do not.

    It seems the controls can still be used in older .NET versions as I can paste code for the controls into my .apsx files in my .NET 4 project and they seem to work OK.

    I need the latest version of the controls and VS as I need to target both touch and mouse devices as well as some older browsers.  Can I safely do this?  What are the implications?

    Hello David,

    Thank you for contacting us.

    Reviewing the details that you provided us, I suppose the reason why you could not access Telerik UI for ASP.NET AJAX in the Visual Studio Toolbox is that the current version of the toolbox controls mismatch the target framework of the project.

    In order to get access to the UI for ASP.NET AJAX toolbox controls in your project, you just need to choose the appropriate controls version. For example: when you have project with .NET 4.0 target framework, the version of the controls should be for .NET 4.0 Framework.

    Changing the controls versions could be done using our Toolbox Configurator wizard. More information about the wizard and how to use it can be found on this: LINK

    Should you have additional questions or need further assistance, do no hesitate to get back to us.
