128        
129        GetUserSummary();
130        
131    </script>   
132    </div>

 

2.后台页面：

Code
 1  protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 2    {
 3        if (e.Row.RowType != DataControlRowType.DataRow) return;
 4
 5        string url = "http://" + Request.Url.Host;
 6        if (e.Row.RowIndex == 0)
 7        {
 8            ((HyperLink)e.Row.Controls[0].FindControl("h1")).NavigateUrl = url + "/Default2.aspx";
 9            //((HyperLink)e.Row.Controls[0].FindControl("h1")).NavigateUrl = url + "/bm/mtTroubleManagelist.aspx?step=6&parm=A";
10            ((HyperLink)e.Row.Controls[0].FindControl("h2")).NavigateUrl = url + "/bm/mtTroubleManagelist.aspx?step=6&parm=B";
11            ((HyperLink)e.Row.Controls[0].FindControl("h3")).NavigateUrl = url + "/bm/mtTroubleManagelist.aspx?step=3";
12        }
13        if (e.Row.RowIndex == 1)
14        {
15            ((HyperLink)e.Row.Controls[0].FindControl("h1")).NavigateUrl = url + "/stm/stmAllTaskList.aspx?parm=A";
16            ((HyperLink)e.Row.Controls[0].FindControl("h2")).NavigateUrl = url + "/stm/stmAllTaskList.aspx?parm=B";
17            ((HyperLink)e.Row.Controls[0].FindControl("h3")).NavigateUrl = url + "/stm/stmTaskAssignToMeList.aspx";
18        }
19        if (e.Row.RowIndex == 2)
20        {
21            ((HyperLink)e.Row.Controls[0].FindControl("h1")).NavigateUrl = url + "/sireq/SIAllReqRecord.aspx?parm=A";
22            ((HyperLink)e.Row.Controls[0].FindControl("h2")).NavigateUrl = url + "/sireq/SIAllReqRecord.aspx?parm=B";
23            ((HyperLink)e.Row.Controls[0].FindControl("h3")).NavigateUrl = url + "/sireq/MyPendingJobSView.aspx";
24        }
25        if (e.Row.RowIndex == 3)
26        {
27            ((HyperLink)e.Row.Controls[0].FindControl("h1")).NavigateUrl = url + "/adm/admAllApplyList.aspx?parm=A";
28            ((HyperLink)e.Row.Controls[0].FindControl("h2")).NavigateUrl = url + "/adm/admAllApplyList.aspx?parm=B";
29            ((HyperLink)e.Row.Controls[0].FindControl("h3")).NavigateUrl = url + "/adm/admApplyWaitForApvList.aspx";
30        }
31    }

 

3.GetUserInfo.aspx的后台代码：

Code
1 protected void Page_Load(object sender, EventArgs e)
2    {
3        Class1 cls = new Class1();
4        string str_CallBack = cls.GetTaskRecord();
5        Response.Clear();
6        Response.Write(str_CallBack);
7        Response.End();
8    }

4.Class1类：

Code
 1 /**//// <summary>
 2    /// 构造用户的工作信息，以字符串返回，在回调的时候刷新页面信息。
 3    /// 下面的数字，可以调用不同的统计方法
 4    /// </summary>
 5    /// <returns></returns>
 6    public string GetTaskRecord()
 7    {
 8        StringBuilder resultStringBuilder = new StringBuilder();
 9        resultStringBuilder.Append(0 + ",")
10                    .Append(0 + ",")
11                    .Append(4 + ";")
12
13
14                    .Append(1 + ",")
15                    .Append(0 + ",")
16                    .Append(3 + ";")
17
18                    .Append(5 + ",")
19                    .Append(7 + ",")
20                    .Append(10 + ";")
21
22                    .Append(0 + ",")
23                    .Append(0+ ",")
24                    .Append(9);
25
26        return resultStringBuilder.ToString();
27    }
28
29    /**//// <summary>
30    /// 构造空的DataSet用户工作信息，给首页绑定数据。
31    /// </summary>
32    /// <returns></returns>
33    public DataSet GetTaskRecordEmpty()
34    {
35        DataSet dsa = new DataSet();
36
37        DataTable tblRecord = new DataTable("Record");
38        DataColumn dc = null;
39        dc = tblRecord.Columns.Add("Title", Type.GetType("System.String"));
40        dc = tblRecord.Columns.Add("TodayAllAdd", Type.GetType("System.String"));
41        dc = tblRecord.Columns.Add("TodayAllClose", Type.GetType("System.String"));
42        dc = tblRecord.Columns.Add("WaitHandle", Type.GetType("System.String"));
43
44        DataRow newRow;
45        newRow = tblRecord.NewRow();
46        newRow["Title"] = "运维事件";
47        newRow["TodayAllAdd"] = 0;
48        newRow["TodayAllClose"] = 0;
49        newRow["WaitHandle"] = 0;
50        tblRecord.Rows.Add(newRow);
51
52        newRow = tblRecord.NewRow();
53        newRow["Title"] = "运维任务";
54        newRow["TodayAllAdd"] = 0;
55        newRow["TodayAllClose"] = 0;
56        newRow["WaitHandle"] = 0;
57        tblRecord.Rows.Add(newRow);
58
59        newRow = tblRecord.NewRow();
60        newRow["Title"] = "资源管理";
61        newRow["TodayAllAdd"] = 0;
62        newRow["TodayAllClose"] = 0;
63        newRow["WaitHandle"] = 0;
64        tblRecord.Rows.Add(newRow);
65
66        newRow = tblRecord.NewRow();
67        newRow["Title"] = "发布管理";
68        newRow["TodayAllAdd"] = 0;
69        newRow["TodayAllClose"] = 0;
70        newRow["WaitHandle"] = 0;
71        tblRecord.Rows.Add(newRow);
72
73        dsa.Tables.Add(tblRecord);
74        return dsa;
75    }

5.data.xml

 1 <? xml version="1.0" encoding="UTF-8" ?>
 2 < root >
 3    < data >
 4      < bb > 这里是XML中的数据。 </ bb >
 5    </ data >
 6    < a >
 7     aa
 8    </ a >
 9 </ root >

这是一个简单的AJAX调用的实例。
