推荐答案

尝试在ajax更新面板中添加你的控件并试一试..

Try to add your control in ajax update panel and try it..

<asp:ScriptManager ID="ScriptManager1" runat="server">
   </asp:ScriptManager>
   <asp:UpdatePanel ID="up1" runat="server">
       <ContentTemplate>
           <asp:TextBox ID="txtDate" CssClass="app_formtext" runat="server" AutoPostBack="True"

               OnTextChanged="txtDate_TextChanged" MaxLength="10" ValidationGroup="check" Height="22px"

               Width="100px"></asp:TextBox>
       </ContentTemplate>
       <Triggers>
           <asp:AsyncPostBackTrigger ControlID="txtDate" />
       </Triggers>
   </asp:UpdatePanel>
