推荐答案
是的，您可以这样做。也就是说，当您保存内容时将页面重定向到单独的页面，它显示您保存的内容或其他内容的详细信息（即使用GET请求的请求页面）。
此模式称为 PRG模式。您可以将此应用于您的ASP.net应用程序。请查看以下链接以获取更多信息。

Yes,You can do something like this.That is ,when you save the content redirect your page into separate page which it shows the details of what you saved or something else (i.e. The requested Page which use GET request).
This pattern is called PRG pattern.You can apply this with your ASP.net app.Please check below link for more info.
Sample
protected void SaveClicked(object sender, EventArgs e)
{
//save changes to database here
//Redirect if all went well
Response.Redirect("http://www.mysite.com/customer.aspx?CustomerId="
+ idOfSavedCustomer.ToString());
}
