如何通过会话将参数从page1.aspx传递给page2.aspx？

我有两个aspx页面。我需要发送一个文本框（record_id）值作为参数从page1.aspx到page2.aspx，以在页面后面的VB代码中的SqlCommand查询中使用。我想使用会话传递此参数。 Page1是一个GridView，它显示来自SQL数据源的记录，并在编辑按钮上单击将用户重定向到page2，该页面填充多个文本框和下拉列表，并允许用户编辑记录。 page1.aspx这个：如何通过会话将参数从page1.aspx传递给page2.aspx？

则可以将问题归结为一个更小的代码示例，并制定一个问题围绕这个问题？ – user492238 2011-06-08 14:36:16

目前尚不清楚你的问题是什么。你的问题陈述似乎是你的答案。 – 2011-06-08 14:48:22

我需要通过选择将grid_view中的record_id文本框值传递给page2.aspx.vb页面以用于填充更新表单的查询中。我无法通过会话将此参数从page1传递给page2。 – 2011-06-08 14:50:57

这就是你需要做什么：

在GridView rowcommand事件。使用命令参数（已经设置）获取record_id。

设置与此会话RECORD_ID

最后做的Response.Redirect或Session.Transfer到Page2.aspx

我有与record_id设置会话的语法有困难。你能提供示例代码吗？ – 2011-06-08 17:43:36

simple session（“record_id”）= ： - ）.... 应该是您的命令参数。 HTH – Raja 2011-06-08 17:45:28

这就是我在后面的代码page1.aspx – 2011-06-08 17:48:28

如何通过会话将参数从page1.aspx传递给page2.aspx？
