ExtJS and. NET development examples (grid data display, paging, sorted)

Recently a lot of friends care about ExtJS, I recently wrote a project management tool used to ExtJS, I combined. Net wrote a case about grid implementation for the needs of friends reference.

This example development environment is: Windows XP + SQL Server + Iis6+vs 2008 Beta2 (. NET Framework3.5)

Implementation steps:

1. Fetch data source

Here is the way to read data from the database to produce JSON for ExtJS grid calls.

(1) Using Scott Guthrie to produce JSON-formatted classes, this article can be accessed: http://weblogs.asp.net/scottgu/archive/2007/10/01/tip, its translation please visit: http:// Blog.joycode.com/scottgu/archive/2007/10/10/109268.aspx

< p> to build a class file JSONHelper.cs, the code is as follows:

JSONHelper.cs

1using System;
2using System.Collections.Generic;
3using System.Text;
4using System.Web.Script.Serialization;
5namespace Web.Components
6{
7　　public static class JSONHelper
8　　{
9　　　 　public static string ToJSON(this object obj)
10　　　　{
11　　　　　　JavaScriptSerializer serializer = new JavaScriptSerializer();
12　　　　　　return serializer.Serialize(obj);
13　　　　}
14
15　　　　 public static string ToJSON(this object obj, int recursionDepth)
16　　　　{
17　　　　　　JavaScriptSerializer serializer = new JavaScriptSerializer();
18　　　　　　serializer.RecursionLimit = recursionDepth;
19　　　　　　return serializer.Serialize (obj);
20　　　　}
21　　}
22}
