JQ网格显示日期与时间，但只想与日期分组

Question

你好我在我的Asp.Net MVC应用程序中使用JQ网格。在我的网格中有一个名为InvoiceDate的字段，我必须将它与InvoiceDate进行分组，InvoiceDate随时间而来，并且在网格中，我必须随时间显示日期，但对于分组，我必须将它与仅日期分组即，如果我有3数据

1. 08/29/2014 13:11:56 
2. 08/29/2014 13:12:45 
3. 08/30/2014 12:09:20 

在网格我有显示日期与上述相同，但是，分组我必须只日期组这意味着

2014年8月29日和2014年8月30日，它是可能的，如果是的话请给我解决方案。 我的代码是

jQuery("#ItemSoldReport").jqGrid({ 
         data: ParsedJson, 
         datatype: "local", 
         height: 'auto', 
         width: 'auto',

您可以使用isInTheSameGroup和formatDisplayField特点，我在the answer建议和包含在jqGrid的开始4.5版本（见here和here）。我希望the answer中包含的the demo提供您需要的所有信息。
