首先，您需要从页面中引用ScriptManager控件。

First you need to take reference of ScriptManager control from your page.

<asp:scriptmanager id="scriptmanager" runat="server"></asp:scriptmanager>

如果已经那里到你的主页然后没有必要。然后从您的mobilevalidate方法中，您可以调用服务器端方法CheckDateTime，如下所示

If it is already there to your masterpage then no need. Then from your mobilevalidate method you can call server side method CheckDateTime like as follows

PageMethods.CheckDateTime("yourargument");

您还可以使用jquery调用该服务器端方法或其他客户端库像原型。如果您在线搜索，那么您会发现许多代码示例。

You can also called that serverside method using jquery or other client side library like prototype. If you search online then you will find many codesample.
