在前面写了两，但不知道如何完成，对比刚刚开始学这个，他们摸着石头过河，一步步。在最后两天DataGridCRUD融合在一起。因此份额。我希望像我这样谁是刚刚开始学习一些帮助。

直接主题酒吧。

它是说数据表，我建立了一个非常easy的表Rex_Test

然后这里就是一般处理程序

Handler5.ashx

<%@ WebHandler Language="C#" Class="Handler5" %>using System;
using System.Web;
using System.Data;
using System.Data.SqlClient;
using System.IO;
using System.Text;public class Handler5 : IHttpHandler {public void ProcessRequest(HttpContext context)  {string command = context.Request.QueryString["test"];//前台传的标示值  if (command == "add"){//调用加入方法  Add(context);}else if (command == "modify"){//调用改动方法  Modify(context);}else if (command == "delete"){Delete(context);}else{Query(context);}//Query(context);}  public bool IsReusable  {  get  {  return false;  }  }public void Add(HttpContext context){context.Response.ContentType = "text/plain";string xx = string.Empty;string tname = context.Request.QueryString["tName"];string temail = context.Request.QueryString["tEmail"];SqlHelp sqla = new SqlHelp();string sqlString = "insert into Rex_Test(tName,tEmail) values('" + tname + "','" + temail + "')";bool aa= sqla.ExecuteNonQuery(sqlString);sqla.SqlClose();if (aa){xx = "True";}else{xx="False";}context.Response.Write(xx);}public void Modify(HttpContext context){context.Response.ContentType = "text/plain";string yy = string.Empty;string id = context.Request.QueryString["ID"];string tname = context.Request.QueryString["tName"];string temail = context.Request.QueryString["tEmail"];SqlHelp sqlb = new SqlHelp();string sqlString = "update Rex_Test set tName='"+tname+"',tEmail='"+temail+"' where ID='"+id+"'";bool bb= sqlb.ExecuteNonQuery(sqlString);sqlb.SqlClose();if (bb){yy = "True";}else{yy = "False";}context.Response.Write(yy);}public void Delete(HttpContext context){context.Response.ContentType = "text/plain";string zz = string.Empty;string id=context.Request.QueryString["ID"];SqlHelp sqlc = new SqlHelp();string strfacc = "delete from Rex_Test where ID='"+id+"'";sqlc.ExecuteNonQuery(strfacc);sqlc.SqlClose();context.Response.Write("True");}/// <summary>  /// 查询记录  /// </summary>  /// <param name="context"></param>  public void Query(HttpContext context)  {  context.Response.ContentType = "text/plain";  //===============================================================  string tkey;tkey = "";  //获取前台传来的值  if (null != context.Request.QueryString["tkey"])  {//获取前台传来的值  tkey = context.Request.QueryString["tkey"].ToString().Trim();  }  //================================================================  //获取分页和排序信息：页大小，页码，排序方式。排序字段  int pageRows, page;  pageRows = 10;  page = 1;  string order, sort, oderby; order = sort = oderby = "";  if (null != context.Request.QueryString["rows"])  {  pageRows = int.Parse(context.Request.QueryString["rows"].ToString().Trim());  }  if (null != context.Request.QueryString["page"])  {  page = int.Parse(context.Request.QueryString["page"].ToString().Trim());  }  if (null != context.Request.QueryString["sort"])  {  order = context.Request.QueryString["sort"].ToString().Trim();  }  if (null != context.Request.QueryString["order"])  {  sort = context.Request.QueryString["order"].ToString().Trim();  }  //===================================================================  //组合查询语句：条件+排序  StringBuilder strWhere = new StringBuilder();if (tkey != "")  {strWhere.AppendFormat("tName like '%{0}%' and ", tkey);  }  //删除多余的and  int startindex = strWhere.ToString().LastIndexOf("and");//获取最后一个and的位置  if (startindex >= 0)  {  strWhere.Remove(startindex, 3);//删除多余的andkeyword  }  if (sort != "" && order != "")  {  //strWhere.AppendFormat(" order by {0} {1}", sort, order);//加入排序  oderby = order + " " + sort;  }  //DataSet ds = Bnotice.GetList(strWhere.ToString());  //调用不分页的getlist  //调用分页的GetList方法  DataSet ds = GetListByPage(strWhere.ToString(), oderby, (page - 1) * pageRows + 1, page * pageRows);  int count = GetRecordCount(strWhere.ToString());//获取条数  string strJson = ToJson.Dataset2Json(ds, count);//DataSet数据转化为Json数据  context.Response.Write(strJson);//返回给前台页面  context.Response.End();  }public int GetRecordCount(string strWhere){SqlHelp sqlx = new SqlHelp();StringBuilder strSql = new StringBuilder();strSql.Append("select count(1) FROM Rex_Test");if (strWhere.Trim() != ""){strSql.Append(" where " + strWhere);}int obj = sqlx.ReturnCount(strSql.ToString());sqlx.SqlClose(); if (obj<=0){return 0;}else{return Convert.ToInt32(obj);}}/// <summary>  /// 分页获取数据列表  /// </summary>  public DataSet GetListByPage(string strWhere, string orderby, int startIndex, int endIndex){SqlHelp sqly = new SqlHelp();try{StringBuilder strSql = new StringBuilder();strSql.Append("SELECT * FROM ( ");strSql.Append(" SELECT ROW_NUMBER() OVER (");if (!string.IsNullOrEmpty(orderby.Trim())){strSql.Append("order by T." + orderby);}else{strSql.Append("order by ID asc");}strSql.Append(")AS Row, T.*  from Rex_Test T ");if (!string.IsNullOrEmpty(strWhere.Trim())){strSql.Append(" WHERE " + strWhere);}strSql.Append(" ) TT");strSql.AppendFormat(" WHERE TT.Row between {0} and {1}", startIndex, endIndex);return sqly.GetDataSet(strSql.ToString());}finally { sqly.SqlClose(); }}  }

最有另一个Json转换类

ToJson.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Text;
using System.Data;
using System.Data.SqlClient;
using System.IO;/// <summary>
///ToJson 的摘要说明
/// </summary>
public class ToJson{/// <summary>/// DataSet转换成Json格式 /// </summary> /// <paramname="ds">DataSet</param>///<returns></returns> public static string Dataset2Json(DataSet ds, int total = -1){StringBuilder json = new StringBuilder();foreach (DataTable dt in ds.Tables){//{"total":5,"rows":[json.Append("{\"total\":");if (total == -1){json.Append(dt.Rows.Count);}else{json.Append(total);}json.Append(",\"rows\":[");json.Append(DataTable2Json(dt));json.Append("]}");}return json.ToString();}/// <summary> /// dataTable转换成Json格式 /// </summary> /// <paramname="dt"></param> ///<returns></returns> public static  string DataTable2Json(DataTable dt){StringBuilder jsonBuilder = new StringBuilder();for (int i = 0; i <dt.Rows.Count; i++){jsonBuilder.Append("{");for (int j = 0; j <dt.Columns.Count; j++){jsonBuilder.Append("\"");jsonBuilder.Append(dt.Columns[j].ColumnName);jsonBuilder.Append("\":\"");jsonBuilder.Append(dt.Rows[i][j].ToString());jsonBuilder.Append("\",");}if (dt.Columns.Count > 0){jsonBuilder.Remove(jsonBuilder.Length - 1, 1);}jsonBuilder.Append("},");}if (dt.Rows.Count > 0){jsonBuilder.Remove(jsonBuilder.Length - 1, 1);}return jsonBuilder.ToString();}}

通过以上几步，基本上能够实现DataGrid的增删改查，其他功能还在学习中。请多多不吝赐教。

哦，对了，我发现这个Jqurey EasyUI DataGrid的一些功能，比方刷新、分页这些在IE11下。不怎么兼容样。假设有知道解决方法的朋友，希望能够留言。给大家分享一下，谢了。

近期有点时间。又来研究了一下这个问题。最终找到了问题所在，原来是method:'get'这里须要改为method:'post'，

这样子改动后。每次操作完毕又一次绑定数据后，就会又一次刷新了。

它似乎还有意向啊。
