       Note that I named this variable to distinguish it from the video
       object passed as the result of the post form. Next, we check if
       the video is found as before. Return Then we update the , and
       properties of and call to update the database. statement will be
       issued based on our updated properties. Finally, we redirect the
       user to the video list.   the application and see if everything
       works. Navigate to and click Edit in front of the first video.
       Make some changes and click the Save button. You will be
       redirected to page why is that.
       This is one of the problems you may encounter when you forget to
       add a hidden field in your form. Let's go back to our actions
       and see why this happens: If you run the application in debug
       mode and place a breakpoint here, you'll see that the value of
       is . Therefore, the request sent to the Phone Number List

       server does not have a video value. It
       only contains values for , and , which come from input fields on
       the form. In order to send the value of , we need to add a
       hidden field. Open and add a hidden field before the Save
       button: Input Type Submit Class Value Save You can add this
       hidden field anywhere here, but my personal convention is to add
       them before the submit button. This way, when I'm looking for a
       hidden field, I always know where to look.

       save it. Everything should work. Next, we'll add the ability to
       delete videos. Delete Video In this section, you will learn how
       to delete data from a database using Entity Framework. Again,
       we'll implement this functionality in two steps: first, we'll
       add a delete link in front of each video in the video list. When
       users click on this link, they will see a page with details of
       the video to be removed.
