    <ContentTemplate >

    <asp:TextBox ID="TextBox23" runat="server"

            style="z-index: 1; left: 745px; top: 177px; position: absolute"

            ontextchanged="TextBox23_TextChanged" ></asp:TextBox>
            <asp:Label ID="Label55" runat="server" Font-Size="Small" ForeColor="Red"

    </asp:UpdatePanel>

它可以工作，但是转到服务器(TextBox23).求助.

It works but goes to server (TextBox23). Plase help.

推荐答案

您期望做什么?
它使用ajax将页面发布到服务器，并且在服务器端进行更改后，它将返回并仅保留ContentTemplate中包含的部分.

And what did you expected to do?
It post the page to the server, using ajax, and after you change something on the server side it will return and refress only the part contained in the ContentTemplate.
