页面间传值

两个页面分别是Buffer.aspx、buffer2.aspx;

从Buffer.aspx中将sessionId传到buffer2.aspx中去

Buffer.aspx中的代码：

   <form id="form1" action="buffer2.aspx" runat="server" method="post">

 

 

      <asp:Button ID="Button1" runat="server" Text="缓冲区分析" PostBackUrl="~/GIS/buffer2.aspx" />
     <asp:HiddenField ID="SESSION" runat="server" />

 

 

   </form>

 

 

Buffer.aspx.cs中的代码：

    protected void Page_Load(object sender, EventArgs e)
    {
        String sessionId = Request.Form.Get("SESSION");
        SESSION.Value = sessionId;

    }

 

buffer2.aspx.cs中的代码:

 protected void Page_Load(object sender, EventArgs e)

{

String sessionId = Request.Form.Get("SESSION");

}
