    Hey,

    Getting the following error : Error Creating Control - OpenAccessDataSource1

    Failed to create designer 'Telerik.OpenAccess.OPenAccessDataSource, Telerik.OpenAccess.Web......

    How can I fix this, do I need to register a dll in the GAC manually????

     

    Thanks,

    Hello Andrew,

    Thank you for contacting us and I am sorry that you are experiencing issues.

    The error on your side is expected with version 2015.3.1221 of Telerik Data Access. It happens because the Linq Data Source Configuration wizard was part of the Visual Studio integration of Data Access and the latter was deprecated in Data Access Q2 2015. As the wizard is not available anymore, the OpenAccessLinqDataSource control can be configured only declaratively. The implementation for the different configuration options is available in this section in our documentation.

    I hope this helps.

    Regards,

    Hi,

    The error you experience on your side is due to the fact that the Visual Studio integration of Data Access was deprecated in Data Access Q2 2015 (the Linq Data Source Configuration wizard includig). Following the tutorial you mentioned will allow you to configure declaratively the OpenAccessLinqDataSource control, but it does not enable the wizard. Hiding the entry point to the deprecated wizard is logged on our side, but at the time present, I am unable to provide you with a specific date when the fix should be released. 

    I am sorry for the inconvenience caused.
