解决方案 »

  1.   

    <Triggers>
    <asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
    </Triggers>
    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
      

  2.   

    你的<Triggers>根本不可能设置为btn_Search_Blur,(根本找不到的)
    因为问题是btn_Search_Blur是tabContainer1中的!!
    所以<Triggers>不要设置!!
    按btn_Search_Blur时需要刷新的用代码!!
    在btn_Search_Blur的click事件中打入以下代码,进行异步刷新,如:up_Style_Sheet.Update();
