    <p>I am building an app using ASP.NET 4.0. </p> <p>I have a table called entries. Entries can be liked via Facebook. I want to implement the ability to sort via likes so I am taking the approach of storing the number of likes for each entry and using that column to order. The problem is the overhead involved in getting the number of likes. I think the method I am using could be improved as right now because fetching data for only 13 entries is taking 4 seconds, which is way too long. </p> <p>I am using the FB graph api and <a href="http://james.newtonking.com/projects/json-net.aspx" rel="nofollow">JSON.NET</a> to parse the response. In the following code I have a List of type Entry, I am getting the like url for the entry using an app setting combined with the entries id. This is what I am doing:</p> <pre><code> foreach (Entry entry in entries) { int likes; try { // the url that is tied to the entry string url = "http://graph.facebook.com/?ids=" + Properties.Settings.Default.likeUrl + "?id=" + entry.EntryId; //open a WebClient and get the results of the url WebClient client = new WebClient(); Stream data = client.OpenRead(url); StreamReader reader = new StreamReader(data); string s = reader.ReadToEnd(); //parse out the response var json = JObject.Parse(s); //shares are how many likes the entry has likes = Convert.ToInt32(json.First.First.SelectToken("shares").ToString()); } catch (Exception ex) { likes = 0; } } </code></pre> <p>As I said this method is very expensive. If anyone could suggest a better way to do what I am attempting here I would really appreciate the help. Thanks much!</p>

    1. COEr.. you have to get the number of likes at least once, do that asynchronously, and you will have a responsive UI meanwhile. After that you can cache it however you like. What is the problem?

    2. COHi. The main issue is it's very slow and time consuming. As I said 13 entries is taking 4 seconds. There will be around 500 entries, which would be over two minutes. I am hoping to find a more efficient way to do this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
