的UpdatePanel和GridView

Question

我有一個UpdatePanel一個GridView像波紋管：

<asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
    <ContentTemplate> 
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" GridLines="None" 
      AllowPaging="True" OnRowCommand="GridViewAllProducts_RowCommand"> 
      <Columns> 
       <asp:TemplateField> 
        <ItemTemplate> 
         <img id="imgImage" src='<%# Bind("Image") %>' class="imgNewsAllNewsUC noBorder" alt="" 
          runat="server" /> 
         <asp:ImageButton ID="ibDelete" CommandName="delete" CommandArgument='<%# Bind("Id") %>' 
          runat="server" /> 
        </ItemTemplate> 
       </asp:TemplateField> 
      </Columns> 
     </asp:GridView> 
</ContentTemplate> 
</asp:UpdatePanel> 

和代碼背後，是像波紋管：

protected void GridViewAllProducts_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "delete") 
    { 
     new ProductC().DeleteBy_Id(Convert.ToInt32(e.CommandArgument)); 

     GridViewAllProducts.DataSource = new ProductC().GetAllProducts(); 
     GridViewAllProducts.DataBind(); 
    } 
} 

當我點擊ibDelete，相關行已刪除數據庫，但該頁面在我刷新頁面之前不會更改。我哪裏錯了？

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> 
    .... 
</asp:UpdatePanel> 

protected void GridViewAllProducts_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "delete") 
    { 
     new ProductC().DeleteBy_Id(Convert.ToInt32(e.CommandArgument)); 

     GridViewAllProducts.DataSource = new ProductC().GetAllProducts(); 
     GridViewAllProducts.DataBind(); 
     UpdatePanel1.Update(); 
    } 
}
