GridView頁腳不工作

Question

我想在GridView頁腳中顯示一個總數 - 在那裏沒什麼不尋常的。我已經按照Microsoft網站上的例子，但它不工作：

<asp:GridView ID="gvTimeOverview" DataSourceID="sdsTimeOverview" AutoGenerateColumns="false" ShowFooter="true" CssClass="gridview" runat="server"> 
      <Columns> 
       <asp:BoundField DataField="DateTimeAdded" HeaderText="Date" DataFormatString="{0:dd/MM/yyyy}" /> 
       <asp:BoundField DataField="DateTimeAdded" HeaderText="Time" DataFormatString="{0:HH:mm}" /> 
       <asp:BoundField DataField="TimeToAdd" HeaderText="Mins Allocated" /> 
      </Columns>  
     </asp:GridView> 

代碼：

protected void gvTimeOverview_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     totalMins += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "TimeToAdd")); 
    } 
    else if (e.Row.RowType == DataControlRowType.Footer) 
    { 
     e.Row.Cells[0].Text = "Totals:"; 
     e.Row.Cells[1].Text = totalMins.ToString(); 
     e.Row.ForeColor = Color.Black; 
    } 
} 

任何想法，爲什麼？

未連接事件處理程序。

<asp:GridView 
     ID="gvTimeOverview" 
     DataSourceID="sdsTimeOverview" 
     AutoGenerateColumns="false" 
     ShowFooter="true" 
     CssClass="gridview" 
     runat="server" 
     onrowdatabound="gvTimeOverview_RowDataBound"> 
....
