Protected Friend Function TryUpdateModel(Of TModel As Class) ( _
	model As TModel, _
	includeProperties As String() _
) As Boolean
'Usage
Dim model As TModel
Dim includeProperties As String()
Dim returnValue As Boolean

returnValue = Me.TryUpdateModel(model, _
	includeProperties)

Type Parameters

TModel

The type of the model object.

Parameters

model
Type: TModel
The model instance to update.
includeProperties
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.

ExceptionCondition
ArgumentNullException

The model parameter or the ValueProvider property is Nothing.

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.
