The type of the model object.


Type: TModel
The model instance to update.
Type: System.String()
A list of properties of the model to update.
Type: System.Web.Mvc.IValueProvider
A dictionary of values that is used to update the model.

You do not have to explicitly specify the generic parameter TModel. Instead, you can let the C# or Visual Basic type inference engine determine the generic parameter TModel by omitting it.

The [Overload:System.Web.Mvc.Controller.TryUpdateModel``1] method is like the [Overload:System.Web.Mvc.Controller.UpdateModel``1] method except that the [Overload:System.Web.Mvc.Controller.TryUpdateModel``1] method does not throw an InvalidOperationException exception if the updated model state is not valid.
