This is my code:
The problem is that 'kendo.messages.es-ES.min.js' is ignored. There are some text that are not translated. Checking every thing we found out that the translations were taken from the 'Kendo.Mvc.resources.dll' in the 'bin/es-ES' folder. This 'dll' has some texts translated and orders not as you can see in the attached image. You can noticed that in the 'kendo.messages.es-ES.min.js' the texts are translated, but in the resulting grid there's not the case.
