为什么一个UpdatePannel中的两个Repeater，点击按钮新增一条记录，一个会即刻刷新，另一个却不会即刻刷新？需要刷新整个页面才会刷新。

“点击按钮新增一条记录”，指的是新增RepeaterFolder中的记录（不会即刻刷新），或新增RepeaterNote中的记录（会即刻刷新）。

  1.   

    另外一个是不是需要执行一下dataBind。
      

  2.   

    重新绑定了吗？在page_load加那个了吗？
      

  3.   

    加啦！部分代码：
     protected void Page_Load(object sender, EventArgs e)
        {
          if (!Page.IsPostBack)
          {
            Folder_bindCount();
            Folder_bind();
            Note_bindCount();
            Note_bind();
          }
        }    void Folder_bind()
        {
          RepeaterFolder.DataSource = Folder_BindData();

            Modal1.Show();
          }
          conn1.Close();
        }
      

  4.   

    应该不会,实在不行重新拖个updatepannel试试
      

  5.   

    需要加这个吗？（环境是VS 2008）
    ...
      </ContentTemplate> 
     <Triggers>
       <asp:AsyncPostBackTrigger ControlID="btnAddFolder3" EventName="Click" />
     </Triggers>
    </asp:UpdatePanel>
      

  6.   

    改为如下代码还是一样。（新增RepeaterFolder中的记录（不会即刻刷新），或新增RepeaterNote中的记录（会即刻刷新）。）
    难道是后台代码错？
    <ajaxToolkit:ToolkitScriptManager ID="ScriptManager1" EnablePartialRendering="true" runat="server" />
