● ObjectDataSource使用：

用FormView+ObjectDataSource組合 添加和刪除資料
<asp:FormView ID="FormView1" DefaultMode="Insert" style="line-height:24px;" runat="server" DataSourceID="ObjectDataSource1">
          <InsertItemTemplate>
           聯 系 人：<asp:TextBox ID="contact" Text='<%# Bind("contact") %>' runat="server" /><span class="red12"> *</span><br />
           <asp:Button ID="Button1" runat="server" CommandName="insert" Text="提交" />
           <div>
           </div>
          </InsertItemTemplate>
        </asp:FormView>
           <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" DataObjectTypeName="Model.HouseRent" TypeName="BLL.HouseRent" OnInserted="ObjectDataSource1_Inserted" InsertMethod="Add">
               <InsertParameters>
                   <asp:Parameter Name="model" Type="Object" />
               </InsertParameters>
           </asp:ObjectDataSource>
