在C＃中的DateTime更新字段GridView

Question

我想在GridView中拆分顯示和更新日期時間。我如何在SqlDataSource的UpdateParameters中重新組合它們？

例如

<asp:SqlDataSource ID="uxTravelTripMeetingDataSource" runat="server" 
      ConnectionString="<%$ ConnectionStrings:MGO %>" 
      ProviderName="<%$ ConnectionStrings:MGO.ProviderName %>" 
      SelectCommand="select * from v_travel_meeting t where travel_trip_id = :travel_trip_id" 
      UpdateCommand="update travel_prospect set person = :person, meeting_date = :meeting_date where prospect_id = :prospect_id and travel_trip_id = :travel_trip_id " 
      <SelectParameters> 
       <asp:QueryStringParameter Name="travel_trip_id" QueryStringField="id" /> 
      </SelectParameters> 
      <UpdateParameters> 
       <asp:Parameter Name="person" /> 
       <asp:Parameter Name="prospect_id" /> 
       <asp:Parameter Name="travel_trip_id"/> 
       <asp:Parameter Name="meeting_date" Type="DateTime" /> 
      </UpdateParameters> 
     </asp:SqlDataSource> 

     <asp:GridView ID="uxTravelTripMeetingGridView" runat="server" 
      DataSourceID="uxTravelTripMeetingDataSource" AutoGenerateColumns="False" 
      DataKeyNames="travel_trip_id,prospect_id"> 
      <Columns> 
       <asp:CommandField ShowEditButton="True" /> 
       <asp:TemplateField HeaderText="Prospect"> 
       <ItemTemplate> 
        <a href="something.aspx?prospectid=<%# Eval("prospect_id") %>&height=500&width=600" title="caption" class="thickbox" ><%# Eval("prospect_name")%> 
       </ItemTemplate> 
       </asp:TemplateField> 
       <asp:BoundField DataField="person" HeaderText="Person" />      
       <asp:TemplateField> 
        <ItemTemplate> 
         <asp:Label ID="Label3" runat="server" 
          Text='<%# Bind("meeting_date", "{0:d}") %>'></asp:Label> 
        </ItemTemplate> 
        <EditItemTemplate> 
         <asp:TextBox ID="TextBox3" runat="server" 
          Text='<%# Bind("meeting_date", "{0:d}") %>' /> 
        </EditItemTemplate> 
       </asp:TemplateField> 
       <asp:TemplateField> 
        <ItemTemplate> 
         <asp:Label ID="Label3" runat="server" 
          Text='<%# Bind("Meeting_time") %>'></asp:Label>&nbsp; 
         <asp:Label ID="Label4" runat="server" 
          Text='<%# Bind("Meeting_am_pm") %>'></asp:Label> 
        </ItemTemplate> 
        <EditItemTemplate> 
           <asp:ObjectDataSource ID="ds15Min" runat="server" OldValuesParameterFormatString="original_{0}" 
      SelectMethod="DDLFifteenMin" TypeName="App" /> 

         <asp:DropDownList ID="DropDownList2" runat="server" 
         DataSourceID="ds15Min" DataTextField="time" DataValueField="display" 
          SelectedValue='<%# Bind("meeting_date","{0:t}") %>' > 
           <asp:ListItem Value=" "> </asp:ListItem> 
          </asp:DropDownList> 
        </EditItemTemplate> 
       </asp:TemplateField> 
      </Columns> 

     </asp:GridView> 

謝謝！

更新命令：

update travel_prospect set person = :person, meeting_date = DATEADD(n,@Date,@Time) 
where prospect_id = :prospect_id and travel_trip_id = :travel_trip_id 

更新參數：

<asp:Parameter Name="Date" Type="DateTime" /> 
<asp:Parameter Name="Time" Type="String" /> 

現在這種解決方案意味着你必須輸入或計算以分鐘爲日期的時間部分（這是什麼ñ在DATEADD意味着）爲了正確地創建它。你如何做到這一點取決於你。
