推荐答案
将你的id存储在会话中并使用其他页面简单
store your id in session and use other page simple
你可以使用查询字符串将值从1页传递给另一页。
在你的第一页 - >
U can use Query String To Pass value form 1 page to another .
In your First page ->
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Page1.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
</head>
<body>
<form id="form1" runat="server" >
<asp:DropDownList id="DropDownList1" runat="server" >
<asp:ListItem value="">Select</asp:ListItem>
<asp:ListItem value="1">Hello</asp:ListItem>
<asp:ListItem value="2">World</asp:ListItem>
</asp:DropDownList>
<asp:button id="btnSubmit" onclick="btnSubmit_OnClick" Text="Click Me" Runat="server"></asp:button>
</form>
</body>
</html>
.cs（第1页后面的代码）
.cs(code behind For 1st page)
protected void btnSubmit_OnClick(object sender, EventArgs e)
{
if (DropDownList1.SelectedItem.Value.Length > 0)
{
Response.Redirect("Page2.aspx?SelectedValue=" + DropDownList1.SelectedValue);
}
}
in第二页创建文本框并在代码后面编写以下代码
.cs（后面的第2页代码）
in second page Create textbox and write following code in code bihind
.cs(2nd page code behind )
protected void Page_Load(object sender, EventArgs e)
{
string v = Request.QueryString["SelectedValue"];
}
它可以通过多种方式完成你可以使用SESSION，或者你可以通过javascript完成，如果你想完成这个任务客户端。
只需通过谷歌并通过会话或javascript搜索他们的任务你就可以在那里得到很好的解决方案..
it can be done through many ways u can u use SESSION or u can done through the javascript if u want to do this task over the client side.
just go through the google and search their this task by session or javascript u can get good solution over there..
