I figured it out.

Thank you so much for your help!

Most likely, you'll be saving your data during a postback on the OnLoad method.  Saving is a quick operation, so I would just save like normal, check the SaveResult enum value returned from the Save(), and call Response.Redirect() if the save successful.  I don't think you'll have to use the AfterSave event to do it.

I'm using asp.net web forms and would like to redirect a user whenever the data they entered successfully saves to the database. I was wondering how to do this using the AfterSave event. Or maybe there's a better way to do it??
