Sharepoint event handler refresh page

Question

I have an event handler that updates an list item on checkedin. However the user doesn't see the updated list until you refresh the page. How would I go about fixing this issue? code in c# Code as follows

 public override void ItemCheckedIn(SPItemEventProperties properties)
        {

            base.EventFiringEnabled = false;


            SPFile file = properties.ListItem.File;
            file.CheckOut();
            properties.ListItem["ManualDisposalSet"] = "True";

            listItem.SystemUpdate(false);

            file.CheckIn("Updating Object", SPCheckinType.OverwriteCheckIn);
            file.Update();

             base.ItemCheckedIn(properties);
            String url = properties.AfterUrl;


        }

Answer 1

Your main problem is that the ItemCheckedIn event is asynchronous, meaning that it will execute after the file has been checked in and the user has been redirected. Instead, if possible in your scenario, try the ItemCheckingIn that is synchronous
