    Hello All,

    I have recently become involved with a project that was started in VS2015 with what i have to assume was the previous version of Telerik UI.  When the project is loaded from my co-workers machine everything is fine.  When I open the same project from our Team Foundation server using VS2017 and the current version of the Telerik UI I get the error message shown in the design tab.  

    I am very new to .net development and the Telerik UI software so if any additional information is needed please let me know.

    Thank you in advance for any assistance.

    Hi Jarrett,

    The errors shown in the attached screenshot are usually related to wrong or not properly updated references to the Telerik DLLs. Please, try the suggestions given in the following article and let us know should you need further assistance on this matter:

    Vessy,

    I have started through the article that was sent and when I got to step 3 I found that I do not have the RadControls folder under the Telerik.  Aside from that issue all of the other suggestions look correct.  

    Have I failed to install something?

    Hi Jarrett,

    The RadControls version was added in our previous versions, but in the latest ones the name of the folder you need is similar to the following one:
    C:\Program Files (x86)\Telerik\UI for ASP.NET AJAX R2 2017\Bin45

    Do you have such path in the installation folder of your machine?

    Hi Jarrett,

    Yes, the path might be different depending on the installed package - I am glad you managed to find the needed DLLs on your machine. Did you manage to resolve the "Error creating control" errors after referring them or should you need further assistance on this matter?
