网格视图单元格返回错误输出

Question

首先你看到我的GridView

现在看第5行（星期四）。我有一个日期2015年1月1日，并且还有一个链接按钮，如点击添加。当我点击第5行的Click to add时获取行的值4.再次点击第6行按钮我得到第5行的值。为什么会这样？如果我犯了任何错误，请帮我解决。我删除了我的数据绑定事件，然后在添加这些事件后得到预期的输出我输出错误。所以问题是我的数据绑定功能。我该如何解决？

我的手机点击事件是

 protected void lnkmonth1_Click(object sender, EventArgs e)
    {
        LinkButton btn = (LinkButton)sender;
        GridViewRow row = (GridViewRow)btn.NamingContainer;
        string id = grdAcademicCalender.DataKeys[row.RowIndex].Value.ToString();
        Label lbldate = (Label)row.FindControl("lbldates1");

        if (lbldate.Text.Length > 0)
        {
            DateTime time = Convert.ToDateTime(lbldate.Text);
            txtdate.Text = time.ToString("yyyy-MM-dd");
            ModalPopupExtender3.Show();
        }
        else
        {
            ModalPopupExtender4.Show();
        }
        bindgridHeader();
        bindgrid();
    }

我有一个DataBound

   protected void grdAcademicCalender_DataBound(object sender, EventArgs e)
    {
        GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
        TableHeaderCell cell0 = new TableHeaderCell();
        TableHeaderCell cell1 = new TableHeaderCell();
        TableHeaderCell cell2 = new TableHeaderCell();
        TableHeaderCell cell3 = new TableHeaderCell();

        cell0.Text = "Days";
        cell0.ColumnSpan = 0;
        cell0.BackColor = ColorTranslator.FromHtml("#F5BCA9");
        row.Controls.Add(cell0);

        if (!string.IsNullOrEmpty(lblmonth1.Text))//January 2015
        {
            cell1.Text = lblmonth1.Text;
            cell1.ColumnSpan = 3;
            cell1.BackColor = ColorTranslator.FromHtml("#F5BCA9");
            row.Controls.Add(cell1);
        }
        else
        {
        }
        if (!string.IsNullOrEmpty(lblmonth2.Text))//February 2015
        {
            cell2.Text = lblmonth2.Text;
            cell2.ColumnSpan = 3;
            cell2.BackColor = ColorTranslator.FromHtml("#F5BCA9");
            row.Controls.Add(cell2);
        }
        else
        {
        }
        if (!string.IsNullOrEmpty(lblmonth3.Text))//March 2015
        {
            cell3.Text = lblmonth3.Text;
            cell3.ColumnSpan = 3;
            cell3.BackColor = ColorTranslator.FromHtml("#F5BCA9");
            row.Controls.Add(cell3);
        }
     grdAcademicCalender.HeaderRow.Parent.Controls.AddAt(0, row);
}

我的aspx是

<asp:GridView ID="grdAcademicCalender" Width="1500"  runat="server" HeaderStyle-BackColor="Wheat" PageSize="40" DataKeyNames="ID"
AutoGenerateColumns="False" ShowHeader="false" OnDataBound="grdAcademicCalender_DataBound" OnRowDataBound="grdAcademicCalender_RowDataBound" >
      <Columns>
      <asp:TemplateField>        
      <ItemTemplate>
         <asp:Label ID="lblshortdate" runat="server" Text='<%#Eval("ShortName") %>'></asp:Label>
     </ItemTemplate>
     </asp:TemplateField>
     <asp:TemplateField>
     <ItemTemplate>
            <asp:Label ID="lbldates1" runat="server" Text='<%#Eval("Dates1") %>'></asp:Label>
      </ItemTemplate>
      </asp:TemplateField>
      <asp:TemplateField>
     <ItemTemplate>       
         <asp:Label ID="lblmonth1" runat="server" Text='<%#Eval("MonthNumber1") %>'></asp:Label>
      </ItemTemplate>
      <ItemStyle Width="1%" />
      </asp:TemplateField>
      <asp:TemplateField>
      <ItemTemplate>       
         <asp:Linkbutton ID="lblevent1" runat="server" Text='<%#Eval("EventField1") %>'></asp:Linkbutton>
         <asp:Linkbutton ID="lnkmonth1" Width="140" runat="server" OnClick="lnkmonth1_Click" Text="Click to add"></asp:Linkbutton>
      </ItemTemplate>

       </asp:TemplateField>
      </Columns>
     </asp:GridView>

如果很难做到，那么当我点击cell1（递增的单元格值）时，帮助我获取cell2值。
