Getting runtime compile error for Tree
posted

Hi Support, 

I am getting the following error when trying to run my Single Page Application (SPA). I had initialized the SPA from the Visual Studio wizard.

Can you please advise?

Thanks,

Jose

    Hello Jose, 

    Thank you for posting in our community!

    As per the error description, I suggest you to make sure you have all the required dll files referenced in the project.

    For example, using Infragistics MVC Helpers require to reference the correct version of Infragistics.Web.Mvc and set it to CopyLocal in the properties.
    When IgniteUI product is installed, the default location for these dll files will be under C:\Program Files (x86)\Infragistics\2016.1\Ignite UI\MVC , where  MVC3 to MVC6 versions will be separated in different folders. Based on what you want to use, reference one of these to use the helpers.     

    You will find an example of referencing the assembly (@using Infragistics.Web.Mvc) and using the IgniteUI MVC Helper with igTree here .
