使用ASP.NET MVC将多个视图返回到一个ActionResult

时间：2009-10-21 09:59:06

标签： asp.net-mvc viewdata

我想要实现的目标是：

Items assigned to me

Item 1 assigned to me
Item 2 assigned to me
Item 3 assigned to me


All open items
Item 1 open to everyone
Item 2 open to everyone
Item 3 open to everyone
Item 4 open to everyone

虽然从目前为止我对MVC的经验是，我必须将数据返回到视图模型，以便能够以下列方式在视图中使用它：

<asp:Content ID="ticketsContent" ContentPlaceHolderID="MainContent" runat="server">
    <div id="hdMain">
        <div id="hdMainTop"><img src="images/hdMainTop.gif" alt="" /></div>
        <div id="hdMainContent">
            <div id="numberOfCalls">Calls assigned to you (<%=Html.ViewData("MyOpenCallsCount")%>)</div>
            <div id="assignedToMe">
                <div id="callHeaders">
                    <table id="callHeadersTbl" cellpadding="0" cellspacing="0">
                        <tr>
                            <td width="54">&nbsp;</td>
                            <td width="270">Subject</td>
                            <td width="148">Logged</td>
                            <td width="120">Updated</td>
                        </tr>
                    </table>
                </div>

                <div id="storePercent"><%=Html.ViewData("OpenCallCount")%><br />
                    Calls Open</div>
                <ul style="font-weight: bold;">
                    <li>&nbsp;<a href="/Calls/Urgent">Urgent:&nbsp;<%=Html.ViewData("UrgentCallCount")%></a><br /><br /></li>
                    <li>&nbsp;<a href="/Calls/High">High:&nbsp;<%=Html.ViewData("HighCallCount")%></a><br /><br /></li>
                    <li>&nbsp;<a href="/Calls/Normal">Normal:&nbsp;<%=Html.ViewData("NormalCallCount")%></a><br /><br /></li>

            <div id="blueBottom"><img src="images/blueboxBottom.gif" /></div>
        </div>
        </div>
</asp:Content>

现在，我的想法，即使我知道它不起作用，基本上是：

'
' GET: /Calls/
<Authorize()> _
Function Index() As ActionResult
    ViewData("OpenCallCount") = callRepository.CountOpenCalls.Count()
    ViewData("UrgentCallCount") = callRepository.CountUrgentCalls.Count()
    ViewData("HighCallCount") = callRepository.CountHighCalls.Count()
    ViewData("NormalCallCount") = callRepository.CountNormalCalls.Count()
    ViewData("LowCallCount") = callRepository.CountLowCalls.Count()

    ViewData("MyOpenCallsCount") = callRepository.CountMyOpenCalls(Session("LoggedInUser")).Count()
    ViewData("UserName") = Session("LoggedInUser")

    Dim viewOpenCalls = callRepository.FindAllOpenCalls()
    Dim viewMyOpenCalls = callRepository.FindAllMyCalls(Session("LoggedInUser"))

    Return View(viewOpenCalls)
    Return View(viewMyOpenCalls)
End Function

我想知道的是，这样做的正确方法是什么？我不知道如何采用正确的方法，我认为我至少在那里有理论，而不是如何实现它。

感谢您提前提供任何帮助。

修改

根据以下评论，我做了以下代码编辑/补充：

Class Calls
    Private _OpenCalls As hdCall
    Public Property OpenCalls() As hdCall
        Get
            Return _OpenCalls
        End Get
        Set(ByVal value As hdCall)
            _OpenCalls = value
        End Set
    End Property
    Private _MyCalls As hdCall
    Public Property MyCalls() As hdCall
        Get
            Return _MyCalls
        End Get
        Set(ByVal value As hdCall)
            _MyCalls = value
        End Set
    End Property
End Class

索引（）操作 

'
' GET: /Calls/
<Authorize()> _
Function Index() As ActionResult
    ViewData("OpenCallCount") = callRepository.CountOpenCalls.Count()
    ViewData("UrgentCallCount") = callRepository.CountUrgentCalls.Count()
    ViewData("HighCallCount") = callRepository.CountHighCalls.Count()
    ViewData("NormalCallCount") = callRepository.CountNormalCalls.Count()
    ViewData("LowCallCount") = callRepository.CountLowCalls.Count()

    ViewData("MyOpenCallsCount") = callRepository.CountMyOpenCalls(Session("LoggedInUser")).Count()
    ViewData("UserName") = Session("LoggedInUser")

    Dim viewOpenCalls As New Calls With {.OpenCalls = callRepository.FindAllOpenCalls()}
    Dim viewMyOpenCalls As New Calls With {.MyCalls = callRepository.FindAllMyCalls(Session("LoggedInUser"))}

    Return View(New Calls())
End Function

然而，行<%=Html.ViewData("MyOpenCallsCount")%>给了我一个End of Statement预期错误。

另外，我确实让它编译一次，但我从Unable to cast object of type 'System.Data.Linq.DataQuery1[CustomerServiceHelpdesk.hdCall]' to type 'CustomerServiceHelpdesk.hdCall'.

行得到了错误Dim viewOpenCalls As New Calls With {.OpenCalls = callRepository.FindAllOpenCalls()}

我哪里出错了？

对于这样的事情，我有点像菜鸟，所以非常感谢任何帮助。

好吧，你不能从一个函数中返回两个值，如果这是你想要做的（标题表明你想要的那样）。
另外，这不是http的工作方式。 a 请求始终只有一个响应。

但是，如果您尝试将viewOpenCalls和viewMyOpenCalls对象同时发送到一个视图，那么您可以将视图设置为同时包含这两个视图的模型。

像这样：

//My VB is a bit rusty so I'm writing this in C#
class Calls {
    public yourDataType OpenCalls { get; set; }
    public yourDataType MyCalls { get; set; }
}

在您的控制器操作中：

return View(new Calls { OpenCalls = viewOpenCalls,  MyCalls = viewMyOpenCalls })

//I gues in VB it would be like this :
Dim viewOpenCalls = callRepository.FindAllOpenCalls()
Dim viewMyOpenCalls = callRepository.FindAllMyCalls(Session("LoggedInUser"))
Return View(New Calls _
    With {.OpenCalls = viewOpenCalls, .MyCalls = viewMyOpenCalls})

在您的视图中，确保它的模型是Calls类的类型。

<%@ Page Inherits="System.Web.Mvc.ViewPage<Calls>" %>

现在，您可以使用<%=Model.OpenCalls %>和<%=Model.MyCalls %>

答案 1 :(得分：2)

一旦我找到了正确的方法（现在就开始），我就开始工作了。

作为参考，这是它应该做的方式：

Public Class TheCalls
Private _OpenCalls As IQueryable(Of hdCall)
Public Property OpenCalls() As IQueryable(Of hdCall)
    Get
        Return _OpenCalls
    End Get
    Set(ByVal value As IQueryable(Of hdCall))
        _OpenCalls = value
    End Set
End Property
Private _AssignedCalls As IQueryable(Of hdCall)
Public Property AssignedCalls() As IQueryable(Of hdCall)
    Get
        Return _AssignedCalls
    End Get
    Set(ByVal value As IQueryable(Of hdCall))
        _AssignedCalls = value
    End Set
End Property
End Class

答案 2 :(得分：1)

1）创建一个ViewData类。这只是一个POCO类，为要在视图上显示的每个数据项定义属性（例如OpenCallCount）

2）创建一个使用此ViewData类的强类型视图。

3）将具有属性集的ViewData类的新实例传递给视图。

这将帮助您避免在任何地方使用魔术字符串（例如，ViewData（“OpenCallCount”）= ...成为myViewDataClass.OpenCallCount = ...）

你可以通过使用两个局部视图类来整理视图，或者使它稍微更通用一些，但它现在可以完成这项任务。
