我有一个“待处理记录页面”，我想计算所有待处理的记录。例如，我想在我的主页中添加“您有（记录数）个新的待处理记录”我想在我的页面中添加它。就像在 Facebook 中一样。从字面上看，它就像一条通知消息:) 例如，我想在我的主页上显示“您有 23 条新的待处理记录”。代码是什么？请帮忙。

这是我主页的截图。我在油漆中编辑。您可以看到我想要显示的标签文本消息。

在此处输入图像描述

这是我的待处理记录页面的代码：

这只是伪代码，但它与您将在代码中放入的内容非常接近。

从 id=Session["ID"].ToString() 的 pendingrecords 中选择 count(id) 作为 PendingRecordCount
