Controller.TryUpdateModel(TModel) Method (TModel, String[])

Namespace:  System.Web.Mvc
Assembly:  System.Web.Mvc (in System.Web.Mvc.dll)

Type Parameters


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.

Return Value

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


The model parameter or the ValueProvider property is a null reference (Nothing in Visual Basic).

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 TMode 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.
