更新时，网格视图中的行不会替换现有行

我目前从事员工休假管理工作。有两个网格视图，一个用于经理，显示特定员工申请的休假，其中包含全部休假详细信息。GridView中有一个状态列，一旦申请休假，就会显示"挂起"。一旦经理登录并点击"更新"列（这是一个超链接），他将重定向到另一个显示休假详细信息的页面，他可以接受或拒绝休假。一旦他完成了这两项中的任何一项，gridview将从Pending中获得更新的设置状态=已接受或已拒绝。

在另一个针对员工的网格视图中，显示了他/她申请的所有假期。即使是网格视图也有状态，一旦他应用，它将显示Pending，而一旦Manager接受/拒绝，它将分别显示两者之一。

员工网格视图中也有超链接列，当他点击时，他将被重定向到另一个页面，显示他申请的休假的详细信息，并且该页面上有一个重新申请休假的按钮。

此重新申请仅适用于被拒绝或处于挂起状态的休假。

问题是，当员工重新申请时，可能是通过编辑详细信息或使用与"已拒绝休假"相同的详细信息。员工的"已拒绝假期"网格视图会更新，但不会被他重新申请的特定"已拒绝"行取代。它将接受新的休假申请。我需要用ReApplied Leave Request将状态从Rejected设置为Pending来替换Rejected Leave Request。

抱歉或是发了很长的帖子，但我想解释一下整个场景。裸着这个。：）

ReAply 的cs代码

   protected void BtnReApply_Click(object sender, EventArgs e)
    {
        MTMSDTO objc = new MTMSDTO();
        int Flag = 0;
        LblLoggedInUser.Text = Session["EmpName"].ToString();
        objc.LoggedInUser = LblLoggedInUser.Text;
        objc.TypeofLeave = LblTypeofLeave.Text;
        string date;
        date = Convert.ToDateTime(TxtBeginDate.Text).ToString("dd/MM/yyyy");
        DateTime dt = new DateTime();
        dt = Convert.ToDateTime(date);
        objc.BeginDate = dt;
        objc.EndDate = Convert.ToDateTime(TxtEndDate.Text);
        objc.Description = TxtDescription.Text;
        objc.NumofDays = Convert.ToInt32(TxtNumofDays.Text);
        objc.Status = LblStatus.Text;
        int X = obj.InsertLeave(objc);
        {
            if (X >= 0)
            {
                Flag = 1;
            }
            else
            {
                Flag = 0;
            }
        }
        if (Flag == 1)
        {
            LblSuccess.Visible = true;
            LblSuccess.Text = "Data Added Successfully and Leave Application Succesfully Sent";
        }
        else
        {
            LblErr.Visible = true;
            LblErr.Text = "Failed To Add Data and Send Leave Request!!!";
        }
        MailMessage message = new MailMessage();
        message.To.Add("");
        message.Subject = "Leave Request";
        message.From = new MailAddress("");
        message.IsBodyHtml = true;
        LblLoggedInUser.Text = Session["EmpName"].ToString();
        objc.LoggedInUser = LblLoggedInUser.Text;
        TxtManager.Text = Session["Manager"].ToString();
        objc.Manager = TxtManager.Text;
        objc.TypeofLeave = LblTypeofLeave.Text;
        objc.NumofDays = Convert.ToInt32(TxtNumofDays.Text.Trim());
        message.Body = "<span style = font-family:Arial,font-size:10pt>";
        message.Body += "Hello <b>" + Session["Manager"].ToString() + "</b>,<br /><br />";
        message.Body += "<b>" + Session["EmpName"].ToString() + "</b>" + "&nbsp; has requested" + "<b>" + "&nbsp;" + LblTypeofLeave.Text + "</b>" + "&nbsp;for" + "<b>" + "&nbsp;" + TxtNumofDays.Text + "&nbsp;" + "</b><br />";
        message.Body += "day/days, kindly login to the portal to Accept or Reject it";
        message.Body += "<br />";
        message.Body += "<br />";
        message.Body += "Thank You.<br />";
        message.Body += "</span>";
        SmtpClient smtp = new SmtpClient("");
        smtp.Send(message);
        LblTypeofLeave.Text = "";
        TxtBeginDate.Text = "";
        TxtEndDate.Text = "";
        TxtDescription.Text = "";
        TxtNumofDays.Text = "";
        LblStatus.Text = "";
    }

员工GridView 的行数据绑定代码

protected void GridViewLeaveHistory_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            HyperLink ViewDetails = e.Row.FindControl("ViewDetails") as HyperLink;
            ViewDetails.NavigateUrl = "ReApply.aspx?LeaveID=" + e.Row.Cells[0].Text;
        }
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ((Label)e.Row.Cells[0].FindControl("Description")).Attributes.Add("style", "word-break:break-all;word-wrap:break-word");
        }
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DataRow pr = ((DataRowView)e.Row.DataItem).Row;
            string status = Convert.ToString(pr["Status"]);
            if (status == "Accepted")
            {
                e.Row.Cells[6].BackColor = System.Drawing.Color.LightBlue;
                e.Row.Cells[7].Visible = false;
            }
            else
            {
                if(status == "Rejected")
                e.Row.Cells[6].BackColor = System.Drawing.Color.Yellow;
                if (status == "Pending")
                e.Row.Cells[6].BackColor = System.Drawing.Color.LightGray;
            }
        }
    }

这是员工的GridView代码

protected void GrdLeaveHistory()
    {
        MTMSDTO objc = new MTMSDTO();
        {
            objc.EmpName = Convert.ToString(Session["EmpName"]);
            DataSet GrdLH = obj.GrdLeaveHistory(objc);
            DataView GrdLeaveH = new DataView();
            GrdLeaveH.Table = GrdLH.Tables[0];
            GridViewLeaveHistory.DataSource = GrdLeaveH;
            GridViewLeaveHistory.DataBind();
        }
    }

if (status == "ReApplied")
                    e.Row.Cells[6].BackColor = System.Drawing.Color.Yellow;
                if (status == "Leave Cancellation Requested")
                    e.Row.Cells[6].BackColor = System.Drawing.Color.LightGray;

 if (LblStatus.Text == "Rejected")
        {
            BtnCancelLeave.Visible = false;
        }
