It is best if you provide me with two separate code-snippets or may be web-links. 回答1: For read-only controls they are the same. For 2 way databinding, using a datasource in which you want to update, insert, etc with declarative databinding, you'll need to use Bind . Imagine for example a GridView with a ItemTemplate and EditItemTemplate . If you use Bind or Eval in the ItemTemplate , there will be no difference. If you use Eval in the EditItemTemplate

Our 404-errorpage works like this: A custom ASP-page checks the URL against a short list of 'special' URLs (e.g. http://example.com/limited-offers ). If the URL is known, it redirects to the actual URL of that page. Otherwise the visitor is redirected to a static errorpage with a 404-statuscode.
