Good Morning,
Over a MVC design pattern generated by visual studio 2013 I added a Grid of Dev. When testing the crud inclusion, exclusion and selection are operating normally. But the change is generating an exception.
The exception occurs in the "this.UpdateModel (ModelItem);" in action "public ActionResult GridViewPartialUpdate" in control "UsersController".
The exception message is "The model of type 'WebApplication1.Usuario' could not be updated.", Where then he unduly criticized some table fields "users" used as an example.
I am attaching the project without the folder "WebApplication1 / bin" and without the "packages" folder. I am also sending a picture exemplicando from the time the update click to the generation of exception and undue criticism. The table creation script is also attached.
I thank the help.
