若是一个page1.aspx向page2.aspx提交的流程,则在page2.aspx的顶部添加如下声明:
<%@ PreviousPageType VirtualPath="~/page1.aspx" %>

设置page1.aspx的PostbackUrl属性为~/page2.aspx。

假设page1.aspx的codebehind中有名为test()的方法,则在page2.aspx中可以这样调用:
  if (PreviousPage != null && PreviousPage.IsCrossPagePostBack)
  {
   return ((page1)PreviousPage).test();
  }


顺便记录一下注册客户端脚本的方法:
static readonly string script = "<script language=\"javascript\">\n" +
"alert (\"Sorry, but we couldn't validate your credit card\");\n" + "</script>";

ClientScript.RegisterStartupScript(script.GetType(), "Error", script);
------------------------------------------
和以前的用法有点不同,所以记录下来了。

ArrayList list = new ArrayList();
foreach (GridViewRow row in GridView1.Rows)
{
 CheckBox box = (CheckBox)row.Cells[3].Controls[1];
 if (box.Checked)
  list.Add(row.Cells[0].Text);
}
return list;

Dim list As ArrayList = New ArrayList()
For Each row As GridViewRow In GridView1.Rows
    Dim box As CheckBox = CType(row.Cells(3).Controls(1), CheckBox)
    If (box.Checked) Then
        list.Add(row.Cells(0).Text)
    End If
Next
Return list
