<asp:ScriptManager ID="ScriptManager1" runat="server"/>

Test controls outside TabContainer:<br />
Result:  <asp:TextBox ID="txtResult" runat="server"></asp:TextBox>
<br />

<cc1:TabContainer ID="TabContainer1" runat="server" Width="600" ActiveTabIndex="0">
    <cc1:TabPanel ID="TabPanel1" runat="server">
        <HeaderTemplate>Calculate</HeaderTemplate>
                    <ContentTemplate>
                        <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
                            <ContentTemplate>
                                <asp:UpdateProgress ID="UpdateProgress1" runat="server" DisplayAfter="0">
                                    <ProgressTemplate>
                                        <div: style="position:absolute; width:100%;height:100%;">
                                            <img style="position:fixed; bottom:50%; left:50%; z-index: 999999;" src="../Images/ajax-loader.gif" alt="" />
                                        </div:>
                                    </ProgressTemplate>
                                </asp:UpdateProgress>

                                First Value:  <asp:TextBox ID="txtFirstValue" runat="server"></asp:TextBox>
                                <br />
                                Second Value: <asp:TextBox ID="txtSecondValue" runat="server"></asp:TextBox>
                                <br />
                                <asp:Button ID="Button1" runat="server" Text="Button" />

                            </contenttemplate>
                        </asp:UpdatePanel>
                    </ContentTemplate>
    </cc1:TabPanel>
</cc1:TabContainer>

控件txtResult不会刷新，尽管UpdatePanel可以正常工作.

The control txtResult is not refreshed, whithout the UpdatePanel works fine.

Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
    txtResult.Text = txtFirstValue.Text + txtSecondValue.Text
End Sub

推荐答案

这就是使用UpdatePanel的全部要点. UpdatePanel范围之外的控件不会更新.您可以在后面的代码中访问它们，因为它们是页面设计器和部分类的一部分，但在部分页面刷新的上下文中不可用.

在不使用UpdatePanel时会刷新，因为您要进行整页回发.

That is the whole point of using an UpdatePanel. Controls outside the scope of the UpdatePanel are not updated. You can access them in the code behind because they are part of the page designer and partial class but they are not usable in the context of an partial page refresh.

It refreshes when not using the UpdatePanel because you doing a full page postback.
