        }
        count = trainingInfoes.Tables[0].Rows.Count;
    }

aspx 页面包含以下代码

<table class="contentRow"  width="900px">
                         <tr     class="cvItemHeader" align="left">
                           <td align="left" >
                                 <div><div    class="cvItemHeaderText"> Training Summary </div>
                               <div class="cvItemHeaderButton">
                                                                     <asp:Button ID="btnAddTraining" runat="server" CssClass="DSEButton4" 
                                                                         Text="Add" onclick="btnAddTrainingInfo_Click" /> </div>                     
                                   </div>
                             </td>

                    </tr>

           <div id="Trainings" runat="server"></div>

                                                </table>

抱歉，我的问题不清楚。 btnTrainingSave_Click 方法将数据存入数据库。将数据保存到数据库后，我需要用 id='Trainings' 更新 div 。我在 btnTrainingSave_Click 方法的末尾调用了 page_load 方法。但它不起作用。谁能帮我我该怎么做？也许这次我的问题很明确了。

概念错误，刷新页面重定向到同一个URL

Page.Response.Redirect(Page.Request.Url.ToString(), true);
