Strongly-Typed ASP.NET MVC with ADO.NET Entity Framework?

I've begun working with ASP. NET MVC which is why I came upon this thread, so I'm not sure if you you're still checking for improvements I don't like the idea of adding the new property to a partial class on the entity framework because it doesn't allow for as much change. Try labeling your Deparment DropDown "Department.Id" like this p> Department: d.

DepartmentId == newPerson.Department. Id) In doing it this way, you don't need to update your Entity at all for a property it should have.

Try labeling your Deparment DropDown "Department. Id" like this Department: The ModelBinding of the MVC Framework will pick up the value and apply it to the "Id" Property of the "Department" Navigation Property. What I found is that the other values of Department are null, but that is not significant.

Now you have a way of retrieving the correct Department Entity and applying it to the Department Navigation Property of the new Person Entity created in the Model Bind to your Action parameter, something like: newPerson. Department = ctx.Department. First(d => d.

DepartmentId == newPerson.Department. Id); In doing it this way, you don't need to update your Entity at all for a property it should have.

Good and clean! Zack, you could also set EntityKey on your controllers Edit method: newPerson. DepartmentReference.

EntityKey = new EntityKey("YourEntities. Department","DepartmentId", int. Parse(Request.

Form"DepartmentId")); – Junior Mayhé Feb 23 '10 at 17:48.

Improve your Edit controlling so that it handles the exceptions that are thrown and redisplays the input the user has typed in so far. I'm sure you were about to ;) Update your view to have validators: Name: and then utilize them in your editing: AcceptVerbs(HttpVerbs. Post) public ActionResult Edit(Person Model) { try { ctx.

AttachUpdated(Model); //extension ctx.SaveChanges(); return RedirectToAction("Index"); } catch { foreach (var err in Model. Errors) ModelState. AddModelError(err.

PropertyName, err. ErrorMessage) return View(Model); } }.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
