ProfileAutoSaveEventArgs Class

Provides data for the ProfileAutoSaving event of the ProfileModule class.

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

'Usage
Dim instance As ProfileAutoSaveEventArgs

The ProfileAutoSaveEventHandler delegate is defined for the ProfileAutoSaving event of the ProfileModule class. You can access the ProfileAutoSaving event of the ProfileModule class in the Global.asax file for your ASP.NET application, as shown in the example for this topic. The ProfileAutoSaving event is raised at the end of page execution if the ProfileManager.AutomaticSaveEnabled property is true.

The Save method automatically determines whether properties that are made up of primitive types, strings, or DateTime objects have been changed, by checking the IsDirty property value for each SettingsPropertyValue in the user profile. The Save method cannot explicitly determine whether a custom class has changed. You can use the ProfileAutoSaving event to determine whether a custom object has been modified and then either continue with the automatic save if the object has been modified or cancel the automatic save if the object has not been modified.

To cancel the automatic profile save operation, set the ContinueWithProfileAutoSave property to false in the ProfileAutoSaving event; otherwise, set the ContinueWithProfileAutoSave property to true.

There may be multiple subscribers to the ProfileAutoSaving event. The ProfileModule will use the last value that the ContinueWithProfileAutoSave property is set to. As a result, it is recommended that you explicitly set the ContinueWithProfileAutoSave property in the ProfileAutoSaving event regardless of whether you are canceling or continuing with the automatic save, as you may need to overwrite the value set by an earlier subscriber.

The following code example shows the ProfileAutoSaving event included in the Global.asax file for an ASP.NET application.

Public Sub Profile_ProfileAutoSaving(sender As Object, args As ProfileAutoSaveEventArgs)
  If Profile.Cart.HasChanged Then
    args.ContinueWithProfileAutoSave = True 
  Else
    args.ContinueWithProfileAutoSave = False 
  End If 
End Sub
