Question

我的asp.net项目中有一个页面，我想要显示员工的出席情况。如果显示P，则不在时，A和节假日H应显示在转发器中。现在在我的网页上我有2个文本框，通过它我可以输入年份和月份，那个月我希望得到参加者。我的数据库表如下。

（1）日历

CalederID  Year  Month     WorkingDays
1          2013  January   1111001111100111110011111001111
2          2013  February  1001111100111110011111001111

等等。这里1代表本月的工作日，0代表星期六和星期日我正在使用这种模式，因为在我的一个页面上我正在检查（sat和sun）复选框并且未经检查其他人因此我知道这些是假期

（2）出勤表

AttendanceID    EmpID PresentDays CalenderID  LeaveDate
1                1      Null         1        2013-01-14
2                1      Null         2        2013-02-15
3                1      Null         4        2013-04-11
4                3      Null         6        2013-06-26

（3）EmpInfo表

EmpID  EmpName  and so on
1       Joe
2      Sandra

现在，当我输入年份和月份时，在我的网页上出现问题我想要显示带有标题的转发器作为日期编号，表示该月的日期。现在，如果月份有30天，则显示30个数字。使用另一个转发器，其必须以如上所述的格式P，A，H显示出席

我的中继器看起来像这样

<table class="table1" >
        <asp:Repeater ID="Repeater1" runat="server">
           <HeaderTemplate>
               <tr>
                    <td>Employee ID</td>
           </HeaderTemplate>
           <ItemTemplate>
                    <td><asp:Label ID="lbldates" runat="server" Text='<%# Eval("Dates") %>' ></asp:Label></td>
            </ItemTemplate>
            <FooterTemplate>
                    <td>TOTAL</td></tr>
               <tr>
           </FooterTemplate>           
       </asp:Repeater>
           <asp:Repeater id="rptAttendance" runat="server" OnItemDataBound="rptAttendance_ItemDataBound">
        <ItemTemplate>
            <tr>
                <td><asp:Label ID="lblEmpName" runat="server" /></td>
                <asp:Repeater ID="rptAttendanceCode" runat="server" OnItemDataBound="rptAttendanceCode_ItemDataBound" >
                    <ItemTemplate><td><asp:Label ID="lblAttendanceCode" runat="server" /></td></ItemTemplate>
                </asp:Repeater>
                </tr>
        </ItemTemplate>
    </asp:Repeater>
        </table>

，背后的代码是

protected void Page_Load(object sender, EventArgs e)
        {


        }

        public void search(object sender, EventArgs e)
        {

            Repeater1.DataSource = dt;
            Repeater1.DataBind();


            string cmdText3 = "SELECT CalenderID, WorkingDays from calender where Year = '" + year.Value + "' and Month = '" + month.Value + "'   ";

            DataTable employees = ds4.Tables[0];

            string cmdText5 = "SELECT EmpID,DAY(LeaveDate) AS LeaveDayOfMonth from attendance where CalenderID = '" + CalenderID + "'   ";

            DataTable attendance = ds5.Tables[0];

            List<Tuple<string, string[]>> info = new List<Tuple<string, string[]>>();
            int calendarID = calender.Rows[0].Field<int>("CalenderID");
            string days = calender.Rows[0].Field<string>("WorkingDays");
            days = days.Replace("1", "P");
            days = days.Replace("0", "H");
            string[] daysList = days.Select(d => d.ToString()).ToArray();
            int present = 0;
        int holidays = 0;

        for (int i = 0; i < daysList.Length; ++i)
        {
            if (daysList[i] == "P")
                present++;

            if (daysList[i] == "H")
                holidays++;

        }

        int working = (monthdays - holidays);
        string total = (present + "/" + working);



        Tuple<string, string[],string> employeeAttendance = null;
        foreach (DataRow employee in employees.Rows)
        {
            employeeAttendance = new Tuple<string, string[],string>(employee.Field<string>("EmpName"), daysList,total);


            foreach (DataRow absentDay in attendance.AsEnumerable().Where(a => a.Field<int>("EmpID") == employee.Field<int>("EmpID")))
            {
                var leaveDay = absentDay.Field<Int64>("LeaveDayOfMonth");
                int leaveDay1 = Convert.ToInt16(leaveDay);
                leaveDay1 = leaveDay1 - 1;
                employeeAttendance.Item2[leaveDay1] = "A";
            }


            info.Add(employeeAttendance);
        }
        this.rptAttendance.DataSource = info;
        this.rptAttendance.DataBind();
        }


    protected void rptAttendance_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Tuple<string, string[],string> info = (Tuple<string, string[],string>)e.Item.DataItem;
            ((Label)e.Item.FindControl("lblEmpName")).Text = info.Item1;
            ((Label)e.Item.FindControl("lbltotal")).Text = info.Item3;
            Repeater attendanceCode = (Repeater)e.Item.FindControl("rptAttendanceCode");
            attendanceCode.DataSource = info.Item2;
            attendanceCode.DataBind();
        }
    }

    protected void rptAttendanceCode_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            ((Label)e.Item.FindControl("lblAttendanceCode")).Text = e.Item.DataItem.ToString();
        }
    }

在后面的代码中，我得到了一个月中的天数，然后将它与一个有31个日期的表格进行比较，从逻辑上我可以看到我的数字，在左下角使用转发器2来显示我的EmpID，现在在下面它们旁边我希望显示出席日期的数字。有人可以告诉我如何做到这一点。我的考勤表中的PresendtDays列是空的，但我不知道如何使用它。请帮助我，我已经尝试了很多个小时，这就是我发布完整代码以便有人帮助我的原因。寻找早期的回应。在此先感谢!!

Answer 1

由于数据库的非常规设计，我不得不做一些主要的数据操作才能使其工作。话虽如此，这是我提出的解决方案。

您需要执行三个额外的查询，而不是SQL语句"SELECT EmpID from empinfo "：

从Calendar表中检索信息：
- SELECT CalendarID，WorkingDays FROM Calendar WHERE年= [年]和月= [月]
- 这将返回一个如下所示的表：
使用CalendarID从Calendar表中检索信息：
- SELECT EmpID，EmpName FROM Employees
- 这将返回一个如下所示的表：
使用第一个查询中的CalendarID从考勤表中检索信息。
- SELECT EmpID，DAY（LeaveDate）AS LeaveDayOfMonth FROM Attendance WHERE CalendarID = [CALENDAR ID]
- 这将返回一个如下所示的表：

完成此操作后，请使用以下 TWO 转发器替换第二个转发器（Repeater2）。第一个转发器（rptAttendance）列出每个员工，第二个转发器（rptAttendanceCode）列出该员工每月的每一天。（注意，我们正在连接到转发器的OnItemDataBound事件，稍后会详细介绍）：

    <asp:Repeater id="rptAttendance" runat="server" OnItemDataBound="rptAttendance_ItemDataBound">
        <ItemTemplate>
            <tr>
                <td><asp:Label ID="lblEmpName" runat="server" /></td>
                <asp:Repeater ID="rptAttendanceCode" runat="server" OnItemDataBound="rptAttendanceCode_ItemDataBound" >
                    <ItemTemplate><td><asp:Label ID="lblAttendanceCode" runat="server" /></td></ItemTemplate>
                </asp:Repeater>
                </tr>
        </ItemTemplate>
    </asp:Repeater>

现在，这就是乐趣的开始！

首先，您需要创建一个数据结构，其中包含员工姓名和每月每天的出勤率。我们将WorkingDays字段用于我们的基线，并将其附加到每位员工的出勤率（取自出勤表）。

//This list (info) holds the employee's name in the first string, and their attendance in the string array
List<Tuple<string, string[]>> info = new List<Tuple<string, string[]>>();
int calendarID = calendar.Rows[0].Field<int>("CalendarID");
string days = calendar.Rows[0].Field<string>("WorkingDays");

将日期类型代码替换为相应的字母

days = days.Replace("1", "P");
days = days.Replace("0", "H");

将其转换为数组，以便我们可以迭代它

string[] daysList = days.Select(d => d.ToString()).ToArray();

现在，我们将遍历每个员工记录并为每个员工创建数据结构。然后我们将在每个员工的休息日进行迭代，并在他们不工作的日子里更新他们的日程表集合。

foreach (DataRow employee in employees.Rows)
{
    employeeAttendance = new Tuple<string, string[]>(employee.Field<string>("EmpName"), daysList);
    foreach (DataRow absentDay in attendance.AsEnumerable().Where(a => a.Field<int>("EmpID") == employee.Field<int>("EmpID")))
{
        employeeAttendance.Item2[absentDay.Field<int>("LeaveDayOfMonth") - 1] = "A";
}
    info.Add(employeeAttendance);
}

以下是每个转发器的ItemDataBound事件处理程序：

protected void rptAttendance_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        Tuple<string, string[]> info = (Tuple<string, string[]>)e.Item.DataItem;
        ((Label)e.Item.FindControl("lblEmpName")).Text = info.Item1;
        Repeater attendanceCode = (Repeater)e.Item.FindControl("rptAttendanceCode");
        attendanceCode.DataSource = info.Item2;
        attendanceCode.DataBind();
    }
}

protected void rptAttendanceCode_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        ((Label)e.Item.FindControl("lblAttendanceCode")).Text = e.Item.DataItem.ToString();
    }
}

以下是完整的代码隐藏：

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            List<Tuple<string, string[]>> info = new List<Tuple<string, string[]>>();
            int calendarID = calendar.Rows[0].Field<int>("CalendarID");
            string days = calendar.Rows[0].Field<string>("WorkingDays");
            days = days.Replace("1", "P");
            days = days.Replace("0", "H");
            string[] daysList = days.Select(d => d.ToString()).ToArray();
            Tuple<string, string[]> employeeAttendance = null;
            foreach (DataRow employee in employees.Rows)
            {
                employeeAttendance = new Tuple<string, string[]>(employee.Field<string>("EmpName"), daysList);
                foreach (DataRow absentDay in attendance.AsEnumerable().Where(a => a.Field<int>("EmpID") == employee.Field<int>("EmpID")))
                {
                    employeeAttendance.Item2[absentDay.Field<int>("LeaveDayOfMonth") - 1] = "A";

                }
                info.Add(employeeAttendance);
            }
            this.rptAttendance.DataSource = info;
            this.rptAttendance.DataBind();
        }
    }

    protected void rptAttendance_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Tuple<string, string[]> info = (Tuple<string, string[]>)e.Item.DataItem;
            ((Label)e.Item.FindControl("lblEmpName")).Text = info.Item1;
            Repeater attendanceCode = (Repeater)e.Item.FindControl("rptAttendanceCode");
            attendanceCode.DataSource = info.Item2;
            attendanceCode.DataBind();
        }
    }

    protected void rptAttendanceCode_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            ((Label)e.Item.FindControl("lblAttendanceCode")).Text = e.Item.DataItem.ToString();
        }
    }
