對於mvc和im，我寫了一份報告，根據國家和零售商獲取數據 - 如果國家沒有零售商，則空表格顯示0 s在列中。MVC：如果沒有價值，我該如何隱藏表格
我希望它做的是跳躍到下一個國家，並在所有
我已經使用
ViewData["retailersForCountry"] = retailersForCountry;
if (retailersForCountry == 0)
{
continue;
}
沒有表現出表，瞭解國家，但該表的頁眉和頁腳仍顯示 - 我怎樣才能完全隱藏它，只顯示下一個表的值？
控制器代碼：
case "CUMLEADS":
// Report Title
ViewData["title"] = reportRequest.Title;
// Store the ReportRequest Id
ViewData["reportRequestId"] = reportRequest.Id;
// number Of COuntries so that we can set our outermost loop
var numberOfCountriesCumLeads = Convert.ToInt32(_reportValueRepository.GetReportPair(reportRequest.Id, "numberOfCountries").Value);
ViewData["numberOfCountries"] = numberOfCountriesCumLeads;
// Our outermost country loop
for (int cumLeadsI = 1; cumLeadsI <= numberOfCountriesCumLeads; cumLeadsI++)
{
int cumulativeTotalForCountry = 0;
// Get the number of Retailers for this country -check that the amount of retailers is not 0 if it is then skip to next country
var retailersForCountry = Convert.ToInt32(_reportValueRepository.GetReportPair(reportRequest.Id, "retailersForCountry" + cumLeadsI).Value);
//TODO
//If retailerForCountry = 0 then go to next country - need to remove the header footer
ViewData["retailersForCountry"] = retailersForCountry;
if (retailersForCountry == 0)
{
continue;
}
ViewData["retailersForCountry" + cumLeadsI] = retailersForCountry;

// get the country name
ViewData["country" + cumLeadsI + "Name"] = _reportValueRepository.GetReportPair(reportRequest.Id, "country" + cumLeadsI + "Name").Value;

// Create a loop that will go through the range of dates that we have in the request

感謝
對於記錄安娜，它被認爲是非常糟糕的形式有這麼長的行動方法。您通常希望將處理放入模型或服務類中。我個人的經驗法則是在操作方法中不超過5行代碼。另外，你應該很少使用ViewData - 如果你剛剛創建了一個模型類，那麼你的很多邏輯將會變得更加簡單和清晰。 – 2012-02-01 15:49:50
謝謝我會查看那 – anna 2012-02-01 16:01:10
是否有一個特定的原因，你把所有這些數據填入查看數據？您將它用作大容量存儲容器，而不是將模型或視圖模型與所有數據一起傳遞。 – 2012-02-01 16:14:26
