链接到单选按钮选择，asp.net c#

寻找答案来拯救世界。

我有一个“文章”页面，其中包含单选按钮列表和文本区域。当用户选择单选按钮时，文本区域将被填充。现在用户希望能够通过 url 链接指向一篇文章。（一切都是动态的，并且是从数据库源中提取的）

通过使用第 3 方工具，我能够获取将链接到用户选择的确切 http 请求（如下）。问题是网址非常长。还有另一种方法可以链接到单选按钮选择吗？这样我就可以修改查询字符串以适应特定的格式。谢谢。

on the search for an answer to save the day.

I have an "articles" page that holds a radiobutton list and a textarea. when the user selects a radio button, the text area is populated. now the users wants to be able to point to an article via a url link. (everything is dynamic and being pulled from a db source)

by using a 3 party tool i was able to grab the exact http request (below) that will link to the users' selection. the problem is the url is extremely long. is there another way to link to the radio button selection? that way i can just modify the query string to fit a specific format. thanks.

无需传递 ViewState。您需要做的就是在 QueryString 中放置一个简单的参数。使 url 类似于：

http://www.mysite.com/MyPage.aspx?selected=1

然后在代码隐藏中查找该参数并选择服务器端按钮。

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        int selected;

        if (int.TryParse(Request.QueryString["selected"], out selected))
            RadioButtonList1.SelectedIndex = selected;
    }
}

No need to pass the ViewState around. What you need to do is put a simple parameter in the QueryString. Make the url something like:

http://www.mysite.com/MyPage.aspx?selected=1

Then look for that parameter in the codebehind and select the button server-side.

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        int selected;

        if (int.TryParse(Request.QueryString["selected"], out selected))
            RadioButtonList1.SelectedIndex = selected;
    }
}
