我開發了一個模塊，它工作正常。我有幾個文本框並提交按鈕。提交文本框值時，我將比較那些與數據庫值並返回結果和顯示。我也用過分頁。這是我的行動方法。Mvc4在View中顯示模型屬性
[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);
}
}
這是查看

上面的代碼工作正常。我有一些困難。內部行動方法我有模型。在模型中我有Count = logDetails.Count。計數將保存返回的行數。當第一次加載頁面時，計數值將爲0，當數據庫中沒有相應的匹配數據時，計數值也將爲0.我想顯示如下所示的消息。
var records = @Html.Raw(Model.Count);
if(records==0)
{
fun_toastr_notify('success','No Records Found');
}
它也可以工作，但它也會在頁面加載第一次（計數爲零）時彈出消息。我可以知道我該如何避免這種情況？提前致謝。
您可以使用Viewbag或Viewdata併爲其設置計數值。如果viewbag爲null，那麼它是第一個請求。當它來自你的動作時，將它設置爲計數，然後你可以在那裏進行比較。 –
