推荐答案

这是一种常见的根本问题，这是一个有点难以解决的问题。有一对夫妇的方式来处理它。你可以使用一种方法来检测刷新页面，如下所示：

That is a common fundamental problem, which is a little harder to solve. There are a couple of ways to deal with it. You could use a means to detecting a page refresh, like this:

这是一个服务器端的方法来对事件作出响应;那么你可以以编程方式取消插入。另一种选择是，以检查是否同一数据previously贴，然后不要做一个双插入。另外，我们使用Telerik的的RadAjaxPanel（虽然在UpdatePanel应该工作一样也行）来处理这个问题，作为POST操作都通过AJAX完成的，所以当你刷新刷新原来的GET请求。

This is a server-side approach to responding to events; you could then cancel the insert programmatically. Another option is to check to see if the same data previously posted, and then don't do a double insert. Alternatively, we use the RadAjaxPanel from Telerik (though the UpdatePanel should work the same too) to handle this, as the POST operations are done through AJAX, so when you refresh it refreshes the original GET request.
