与服务器通信时出现ASP.Net错误的jTable

Question

我一直试图让我的jtable从aspx c＃代码开始工作。我想是ASP.net。

但是在用了几天搞乱之后，我仍然无法弄清楚在运行aspx时我犯了哪个错误给了我这个错误。：

  

与服务器通信时发生错误。

以下是我所做的脚本。它正在启动jtable以及List，Create，Delete和Update所需的操作列表。

<script type="text/javascript">

    $(document).ready(function () {

        //Prepare jtable plugin
        $('#UserTableContainer').jtable({
            title: 'User Management System',
            paging: false,
            pageSize: 20,
            sorting: true,
            defaultSorting: 'userName',
            actions: {
                listAction: '/administrator/ADMUser.aspx/userList',
                createAction: '/administrator/ADMUser.aspx/userCreate',
                updateAction: '/administrator/ADMUser.aspx/userUpdate',
                deleteAction: '/administrator/ADMUser.aspx/userDelete'
            },
            fields: {
                userId: {
                    key: true,
                    create: false,
                    edit: false,
                    list: false
                },
                userName: {
                    title: 'Username',
                    width: '23%',
                    create: true,
                    edit: false,
                    list: true
                },
                userFullname: {
                    title: 'Full Name',
                    width: '23%',
                    create: true,
                    edit: true,
                    list: true
                },
                userEmail: {
                    title: 'Email address',
                    list: true,
                    create: true,
                    edit: true
                },
                userPassword: {
                    title: 'User Password',
                    type: 'password',
                    list: false,
                    edit: true,
                    create: true
                },
                CreatedDate: {
                    title: 'Date Created',
                    width: '15%',
                    type: 'date',
                    create: false,
                    edit: false,
                    list: true,
                    displayFormat: 'yy-mm-dd'
                },
                userRole: {
                    title: 'User Roles',
                    width: '15%',
                    create: true,
                    edit: true,
                    list: true,
                    options: '/Administrator/ADMMembersManagement.aspx/GetUserRoles',
                    sorting: false
                }
            }
        });

        $('#UserTableContainer').jtable('load');
    });
</script>

然后，接下来是具有方法的ASPX.CS代码。

请注意，我将getUserList方法放在UserManager中作为返回用户对象的一个​​。不确定我是否正确，但我发现有些人尝试使用SQL中的存储过程。但是，我对存储过程不确定，但我已经在普通的SQL查询命令中完成了它。

[WebMethod(EnableSession = true)]
    public static object userList(int jtStartIndex = 0, int jtPageSize = 0, string jtSorting = null)
    {
        try
        {
            UserManager um = new UserManager();
            //Get data from database
            List<TemplateUser> students = um.getUserList(jtStartIndex, jtPageSize, jtSorting);
            int memberCount = um.TotalNumberOfUsers;

            //Return result to jTable
            return new { Result = "OK", Records = students, TotalRecordCount = memberCount };
        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex.Message);
            return new { Result = "ERROR", Message = ex.Message + "REALLY HERE" };
        }

    }

最后，我的UserManager代码，我将我的getUserList方法存储在。

中

 public List<TemplateUser> getUserList(int inStartIndex, int inPageSize, string inSort)
    {
        List<TemplateUser> userList = new List<TemplateUser>();
        TemplateUser user;
        SqlDataAdapter da = new SqlDataAdapter();
        SqlCommand cmd = new SqlCommand();
        DataSet ds = new DataSet();
        SqlConnection con = new SqlConnection();

        string connString = ConfigurationManager.ConnectionStrings["WEBA_Assignment"].ConnectionString;
        con.ConnectionString = connString;
        cmd.CommandText = "SELECT * FROM (SELECT ROW_NUMBER() OVER (ORDER BY userName ASC) AS Row, * FROM Users) AS StudentsWithRowNumbers WHERE Row > @inStarIndex AND Row <= @inPageSize ";
        cmd.Parameters.Add("@inStartIndex", SqlDbType.Int);
        cmd.Parameters["@inStartIndex"].Value = inStartIndex;
        cmd.Parameters.Add("@inPageSize", SqlDbType.Int);
        cmd.Parameters["@inPageSize"].Value = inPageSize;
        da.SelectCommand = cmd;
        con.Open(); 
        da.Fill(ds, "UserData");
        con.Close();
        foreach (DataRow dr in ds.Tables["UserData"].Rows)
        {
            user = new TemplateUser();
            user.userId = int.Parse(dr["userId"].ToString());
            user.userName = dr["userName"].ToString();
            user.userPassword = dr["userPassword"].ToString();
            user.userFullname = dr["userFullname"].ToString();
            user.userEmail = dr["userEmail"].ToString();
            user.ActivationStatus = int.Parse(dr["ActivationStatus"].ToString());
            user.userRole = int.Parse(dr["userRole"].ToString());


            int year; int month; int day; int hour; int minute; int second;
            year = ((DateTime)dr["CreatedDate"]).Year;
            month = ((DateTime)dr["CreatedDate"]).Month;
            day = ((DateTime)dr["CreatedDate"]).Day;
            hour = ((DateTime)dr["CreatedDate"]).Hour;
            minute = ((DateTime)dr["CreatedDate"]).Minute;
            second = ((DateTime)dr["CreatedDate"]).Second;

            user.CreatedDate = new DateTime(year, month, day, hour, minute, second);
            cmd.CommandText = "Select Count(*) 'NumOfRows' FROM Users";
            da.SelectCommand = cmd;
            con.Open();
            da.Fill(ds, "NumOfRows");
            con.Close();
            TotalNumberOfUsers = int.Parse(dr["NumOfRows"].ToString());
            userList.Add(user);
        }
        return userList;
    }//getUserList

我真的很担心这个问题，因为我不确定从哪里开始继续。最初我没有为jtable完成Startindex和Paging，但是我已经看到了其他一些用户的问题，这些问题有必要的答案，然后我将它们放入。< / p>

但仍然......没有结果......
