推荐答案

尝试此

try this

<asp:LinkButton

                ID="lnk_Back"  OnClientClick="history.go(-1);" runat="server">Back</asp:LinkButton>

您可以执行很多选择.

为了获得总体思路，请在msdn中查看此页面；

ASP.NET会话状态概述 [选项链接 [ ^ ]

一个基本的代码示例是;

You have numerous of options to do that.

In order to get the general idea have a look at this page in msdn;

ASP.NET Session State Overview[^]

Option link[^]

A basic code example is;

object sessionObject = Session["someObject"];
if (sessionObject != null) {
 myLabel.Text = sessionObject.ToString();
}

当我返回上一页时，页面中存在的内容将被清除.我希望在移回时保留相同的内容.

这行听起来像当您单击后退"按钮时，您希望页面的状态相同，

简单的方法是，无论何时，只要您在执行Response.Redirect()行之前单击下一步"按钮，这将带您进入新页面.首先，您必须将所有所需的值(单击后退"按钮单击到会话"变量中以及单击单击"时)返回按钮，您必须再次将已经存储在Session变量中的那些值分配给各自的控件....

好吧，这有点冗长的过程，但是一旦您了解了它，对您来说就很容易了.

全部d最佳.
希望对您有帮助.

Well it''s little bit lengthy procedure but once you understand it it is a very easy thing for you.
