網格中的頁腳模板顯示

Question

我有一個頁腳模板，它會將我的文本框添加到網格中。即使網格中沒有數據，我也想顯示頁腳模板。

<asp:GridView AutoGenerateColumns="false" EnableViewState="true" 
      ID="gvServiceGoalsAndFactors" runat="server" GridLines="None" BorderWidth="1" BorderColor="Brown" 
      AlternatingRowStyle-BackColor="Cyan" HeaderStyle-BackColor="ActiveCaption" ShowFooter="true">    
      <Columns>     
       <asp:TemplateField HeaderText= "Service Goal" >      
        <HeaderTemplate>Service(%)</HeaderTemplate> 
        <ItemStyle HorizontalAlign="Center" /> 
        <ItemTemplate>       
        <asp:Label ID="lblGoal" Visible="true" runat="server" Text='<%# Eval("Service") %>' />                     
        </ItemTemplate> 
        <FooterTemplate> 
        <asp:TextBox ID="txtService" Style="margin-left: 350px" Visible='<%# IsInEditMode %>' runat="server" Text='<%#Eval("Service")%>' MaxLength="10"> 
        </asp:TextBox>                
        </FooterTemplate> 
       </asp:TemplateField> 
       <asp:TemplateField > 
        <HeaderTemplate>Service Factor</HeaderTemplate> 
        <ItemStyle HorizontalAlign="Center" /> 
        <ItemTemplate> 
        <asp:Label ID="lblFactor" Visible='<%# ! IsInEditMode %>' runat="server" Text='<%# Eval("Factor") %>' /> 
        <asp:TextBox ID="txtFactor" Visible='<%# IsInEditMode %>' runat="server" Text='<%#Eval("Factor")%>' MaxLength="10"> 
         </asp:TextBox>
