Hi Marcab,

Based on the provided information, I suspect that the utilized edit mode is PopUp, is that correct? And you would like to render a custom template whenever the grid enters edit mode? 

If so, what I can recommend is that you create a custom view and reference it via the options of the grid:

 .Editable(ed => ed.Mode(GridEditMode.PopUp).TemplateName("CustomTemplateName"))

Within the "CustomTemplateName", you could set any content of your choice. A complete example for the certain functionality could be found in the following repository on GitHub:

https://github.com/telerik/ui-for-aspnet-mvc-examples/blob/master/grid/custom-popup-editor/KendoUIMVC5/Views/Home/Index.cshtml

Let me know in case additional assistance is required.

Thanks Tsvetomir!

I'm using a template, as you suggested above. 

I managed to get it working. I'm still not sure what was causing the error. I simply created a brand new template (with a different name) referenced it accordingly in my grid - and it worked.

Maybe this was some sort of obscure Visual Studio Issue?

Anyway, thanks again for taking the time to reply.

Hi Marcab,

Occasionally, Visual Studio caches route to certain files and reuse them. Also, it is important to point out in case the caching of the browser is enabled, you might need to clear this as well. Google Chrome is famous for its caching capabilities. 

Nevertheless, I am very happy to hear that the issue is resolved. I will go ahead and close this thread. In case you encounter any further issues, post a new message here and the thread would become active once again.

Best wishes,
