我开发了一个模块，它工作正常。我有几个文本框并提交按钮。提交文本框值时，我将比较那些与数据库值并返回结果和显示。我也用过分页。这是我的行动方法。Mvc4在View中显示模型属性
[HttpGet]
public ActionResult Index(int? clientId, DateTime? dateofAction, int? doc_typeid, string employeeID,string citizenId,int? currentFilter, DateTime? filterdateTime,int? filterdocType,string filteredemployeeID,string filteredcitizenId,int? page)
{
logDetailsEnumeration model = new logDetailsEnumeration();
DB_KYC3Entities db = new DB_KYC3Entities();
var docTypes = from c in db.tm_doc_type select c;
if (clientId != null)
{
page = 1;
}
else
{
clientId = currentFilter;
}
if(dateofAction!=null)
{
page = 1;
}
else
{
dateofAction = filterdateTime;
}
if(doc_typeid != null)
{
page = 1;
}
else
{
doc_typeid = filterdocType;
}
if(employeeID!=null)
{
page = 1;
}
else
{
employeeID = filteredemployeeID;
}
if(citizenId!=null)
{
page = 1;
}
else
{
citizenId = filteredcitizenId;
}
ViewBag.CurrentFilter = clientId;
ViewBag.filterdateTime = dateofAction;
int pageSize = 8;
int pageNumber = (page ?? 1);
VerificationLogBAL obj = new VerificationLogBAL();
int docType = obj.GetDocDetails(doc_typeid?? default(int));
List<logDetails> logDetails = obj.getlogDetails(clientId?? default(int), dateofAction??DateTime.Now, docType, employeeID, citizenId);
IPagedList<logDetails> pagedLog = logDetails.ToPagedList(pageNumber, pageSize);
model = new logDetailsEnumeration()
{
doc_typeid= doc_typeid,
Count=logDetails.Count,
employeeID = employeeID,
citizenId= citizenId,
logDetails = pagedLog,
doctype_name=new SelectList(docTypes, "doc_typeid", "doctype_name")
};
return View("Index",model);
}
}
这是查看

上面的代码工作正常。我有一些困难。内部行动方法我有模型。在模型中我有Count = logDetails.Count。计数将保存返回的行数。当第一次加载页面时，计数值将为0，当数据库中没有相应的匹配数据时，计数值也将为0.我想显示如下所示的消息。
var records = @Html.Raw(Model.Count);
if(records==0)
{
fun_toastr_notify('success','No Records Found');
}
它也可以工作，但它也会在页面加载第一次（计数为零）时弹出消息。我可以知道我该如何避免这种情况？提前致谢。
您可以使用Viewbag或Viewdata并为其设置计数值。如果viewbag为null，那么它是第一个请求。当它来自你的动作时，将它设置为计数，然后你可以在那里进行比较。 –
