推荐答案

是什么阻止了您?听起来很简单.

您可以通过多种方式从第二个页面访问第一个页面，例如:
1.查询字符串(如果正在导航)
2. PreviousPage概念(如果不导航)

您所需要做的就是将标记从另一页面传递到一页.你有没有尝试过?
如果您遇到问题，请这样做并发布特定问题.

Whats stopping you? All sounds straight and simple.

You have various ways to access the 1st page from 2nd, for example:
1. Querystring (if navigating)
2. PreviousPage concept (if not navigating)

All you need is to pass on the flag to one page from other. Did you try at all?
Please do so and do post specific issue, if you face.

u可以将查询字符串从第二页传递到第一页

在第二页按钮上，单击u可以写
response.redirect(firstpage.aspx?id = 1);

那么在首页加载时，您就可以做到
if(Convert.Tostring(Request.Querystring ["id"])=="1")
button.Enabled = true;

u can pass querystring from second page to first page

on second page button click u can write
response.redirect(firstpage.aspx?id=1);

then on first page load u can do
if(Convert.Tostring(Request.Querystring["id"])=="1")
button.Enabled=true;

第二页

按钮单击事件

in second page

on button click event

    protected void Button1_Click(object sender, EventArgs e)
{
Response.Redrect("Ur firstpage.aspx?id=1");
}

在您的第一页page_load

in ur first page in page_load

if(convert.Tostring(Request.Querystring["id"]=="1"s)
{
button1.Enabled=True;
}
else
{
button1.Enabled=False;
}

试试吧
