Entity framework update existing entity without ASP.NETMVC TryUpdateModel

Question

Hello, I'm new to EF and I've been using the asp.net mvc databind method to update my models "tryupdatemodel", now I have to update a entity from a service layer, since TryUpdateModel is a asp.net mvc method I can't use it in the services layer.

What I need to do to update the data of an entity without using this method?

I'm using repositories.

Answer 1

There's no automatic way for doing that, you must load the entity from the database and update the properties yourself.

Answer 2

Don't use it in service layer. You could place similar code in Controller:

var entity = Service.Get(id); //get updated entity
TryUpdateModel(entity);
if (ModelState.IsValid)
  Service.Save(entity); //here you can save to database and perform additional validation
