计算Gridview内的记录并显示标签消息
我有一个“待处理记录页面”我想要计算待处理的所有记录。例如，我想在我的主页中添加“你有（记录数）新的待处理记录”我想在我的页面中添加它。就像在Facebook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看到“你有23个新的待处理记录”。那是什么代码？请帮忙。
这是我的主页的屏幕截图。我在油漆编辑。您可以看到我想要显示的标签文本消息。
这是我的Pending Records页面的代码：

<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace = "System.Data.SqlClient" %>
<%@ Import Namespace= "System.Data.OleDb" %>

这只是伪代码，但它与您在代码中的内容非常接近。
从pendingrecords中选择count（id）作为PendingRecordCount，其中id = Session [“ID”]。ToString（）
