Order By With Order By (orderby in C#, without the space that VB.NET uses) you can sort the items in the result collection. Order By is followed by an optional Ascending or Descending (ascending and descending in C#) keyword to specify sort order. You can specify multiple criteria by separating them with a comma. The following query returns a list of genres first sorted by SortOrder in descending order, then sorted on their Name in ascending order (the default): var allGenres = from g in myEntities.Genres orderby g.SortOrder descending, g.Name select g; Where Just like the WHERE clause in SQL, the Where clause in LINQ (where in C#) enables you to filter the objects returned by the query.

For example, to retrieve the number of reviews, you can execute this query: var numberOfReviews = (from r in myEntities.Reviews select r).Count(); Introducing Ajax The server processes that page and sends back the resulting HTML. The browser then parses that HTML and renders the page to the user, optionally downloading any external resources like images, script files, and CSS style sheets. When a user then interacts with the page (for example, by clicking a button to submit a filled-in contact form) the page is posted back to the server, after which the entire page is loaded in the browser again . Though this model has been used for years to serve web pages, it has a few big drawbacks. First, because the entire page is loaded after a postback, the HTML sent to the browser is much larger than it needs to be. The second drawback of a full page reload has to do with the way the browser renders the page. Because the entire page is replaced, the browser has to dismiss the old one and then draw the new one. This causes the page to “flicker,” which results in an unattractive use r experience. Ajax techniques can be deployed to overcome these two problems The concepts behind Ajax have been around for many years. Browsers since Internet Explorer 5 have shipped with the XMLHttpRequest object that enabled you to make calls to the server from JavaScript to send and receive data.
