Type Parameters


The type of the model object.

The model instance to update.

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.

Return Value

Type: System.Boolean
true if the update is successful; otherwise, false.

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 TryUpdateModel method is like the UpdateModel method except that the TryUpdateModel method does not throw an InvalidOperationException exception if the updated model state is not valid.
