Edit controller action

The same changes that we discussed with respect to the SelectList collection must be made to the Edit action as well:

    public async Task<IActionResult> Edit(int? id)
    {
      ...
      ViewData["BlogId"] = new SelectList(_context.Blog, "Id", "Url",
        post.BlogId);
      return View(post);
    }

The following screenshot shows the URL mapped to the BlogId control, and as part of the exercise, kindly make changes to the BlogId label with the literal changes you made in the Creating controller action section:

Edit a post

The same change needs to be applied to the Post action of Edit as well:

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Edit(int id, 
     [Bind("Id,BlogId,Content,PublishedDateTime,Title")] Post post)
    {
      ...
      ViewData["BlogId"] = new SelectList(_context.Blog, "Id", "Url",
        post.BlogId);
      return View(post);
    }

The changes were reflected in the updated item that was displayed on the screen:

List view with edited post

We have updated the references to the Blog ID with Blog URLs in the Post Edit (HTTP, Get, and Post) action. Let's update this on the remaining DELETE action.
