[英]Passing data from view to controller and controller to view
我將日期從視圖傳遞到控制器,然后從控制器到視圖將獲得這兩個日期之間的記錄數。 由於將提取一條記錄,因此我使用IEnumerable,以便顯示記錄列表。 但是在使用IEnumerable時,它無法從視圖中傳遞選定的日期並傳遞給控制器。 誰能解釋我為什么?
這是我的代碼:
視圖:Index.aspx

todate.value = document.getElementById("txtToDate").value;

}
$(function () {
$("#txtToDate").datepicker({

使用IEnumerable時顯示編譯錯誤
Line 49: <%: Html.ValidationSummary(true, "Profile Updation was unsuccessful. Please correct the errors and try again.") %>
Line 50:
Line 51: **<%= Html.HiddenFor(model=>model.Date_Created) %>
Line 52: <%= Html.HiddenFor(model=>model.Date_Modified) %>**
Line 53: <table>
編譯器錯誤消息:CS1061:'System.Collections.Generic.IEnumerable'不包含'Date_Created'的定義,並且找不到擴展方法'Date_Created'接受類型為'System.Collections.Generic.IEnumerable'的第一個參數(您是否缺少using指令或程序集引用?)
嘗試這樣:
<% foreach (var date in Model) { %>
<%= Html.HiddenFor(date=>date.Date_Created) %>
<%= Html.HiddenFor(date=>date.Date_Modified) %>
<% } %>
希望能幫助到你。
在這種情況下,您的視圖模型是IEnumurable。 它僅包含在枚舉器上定義的方法。 您有兩個選擇。
選項一:定義如下的視圖模型
public class MyViewModel {
public CRM_Doctor_Request ReportRequests { get; set;}
public DateTime Date_Created { get; set;}
public DateTime Date_Modified { get; set;}
}
現在,您可以使用此視圖模型將數據傳遞到視圖。
第二個選擇:使用ViewBag將日期傳遞到視圖。 在您的控制器中
ViewBag.Date_Created = dateCreated;
ViewBag.Date_Modified = dateModified;
現在可以從視圖中訪問這些值
就個人而言,由於清潔,我會選擇第一種
