问题描述

您好。



我已经通过Asp.net 4和sqlserver 2008制作了一个应用程序（sruvey）用户选择一个项目（单选按钮）并提交他们的响应将被插入到数据库中。



i想在每个页面中创建一个按钮，当用户想要修改他的答案时，能够返回上一页并更新他们。



所以我在一个页面上放了一个按钮，将页面重定向到上一页，但我在单选按钮中的所有答案都被删除了，而且没有我的回复的内容


页面内的
。代码用于按钮如下：

Hello.

I have made an application (sruvey) by Asp.net 4 and sqlserver 2008 which users select an item (Radio button) and submit their response which will be inserted into the database.

i would like to make a button in each page that when user wanted to modify his answers be able to return to previous page and Update them.

so i have put a button in one page which redirect the page toward previous page , but all of my answers in radio button are removed totoally and there is no trce of my responses

inside the page. the code is for button is below:

Response.Redirect("GeneralCourse.aspx"); //this is the .net code which redirect page to back page

< br $> b $ b

<form id="fro"  runat="server">
              <asp:ImageButton ID="ImageButton1" runat="server" Height="43px"

             BorderWidth="1px" onclick="ImageButton1_Click1"  />
     </form> 

so我该怎么办？

推荐答案

要么传递结果单选按钮选择上一页为 QueryString 或使用重定向> javaScript 。



查看文章如何返回ASP.NET 2.0中的上一页 [ ^ ]了解有关重定向到上一页。

Either pass the result of the Radio Button selection to the previous page as a QueryString or Redirect using javaScript.

Check the article How to go back to the previous page in ASP.NET 2.0[^] to know more on redirecting to previous page.
