Question

在我的页面上，我使用了与

相同的PartialView的2个实例

<div>
        @Html.Partial("AddressPartial1", Model.Address1)   
</div>
<div>                                           
        @Html.Partial("AddressPartial2", Model.Address2) 
</div>

通过传递InstanceName并将其连接到字段名称，我可以为PartialView中的所有字段获取两个实例的唯一ID。现在的问题是当我发布我的页面时，我没有得到我的两个视图的模型对象。我可以使用FormCollection读取控件的值，但我正在寻找更好的解决方案，以便在同一页面上使用2个PartialView实例。提前谢谢！

这是我的代码：

模型（对于我的页面）：

Private m_Address1 As New AddressModel("Address1")
    Public Property Address1() As AddressModel
        Get
            Return m_Address1
        End Get
        Set(ByVal value As AddressModel)
            m_Address1 = value
        End Set
    End Property

   Private m_Address2 As New AddressModel("Address2")
    Public Property Address2 () As AddressModel
        Get
            Return m_Address2 
        End Get
        Set(ByVal value As AddressModel)
            m_Address2 = value
        End Set
    End Property

PartialView模型：

Public Class AddressModel
    Public Sub New()

    End Sub

    Public Sub New(ModelInstanceName As String)
        m_ModelInstanceName = ModelInstanceName
    End Sub

    Private m_ModelInstanceName As String
Private m_StreetAddress1 As String
    Private m_StreetAddress2 As String
    Private m_City As String
    Private m_State As String
    Private m_ZipCode As String

Public Property ModelInstanceName As String
        Get
            Return m_ModelInstanceName
        End Get
        Set(value As String)
            m_ModelInstanceName = value
        End Set
    End Property

Public Property StreetAddress1() As String
        Get
            Return m_StreetAddress1
        End Get
        Set(ByVal value As String)
            If (value IsNot Nothing) Then value = value.Trim()
            If (String.IsNullOrWhiteSpace(value)) Then value = Nothing

            m_StreetAddress1 = value
        End Set
    End Property

和其他属性......

部分视图：

@ModelType AddressModel
<table style="padding-left: 5px; padding-bottom: 10px; width: 99%">
    <tr>
        <td colspan="4">
            <div class="editor-label">
                <span class="required">@Html.LabelFor(Function(m) m.StreetAddress1)</span>
                </div>
                <div class="editor-field">
                    @Html.TextBox(Model.ModelInstanceName + "_StreetAddress1", Model.StreetAddress1, New With {.style = "width:390px"})
                    @Html.ValidationMessageFor(Function(m) m.StreetAddress1)
                </div>
            </td>
        </tr>
        <tr>
            <td colspan="4">
                <div class="editor-field">
                    @Html.TextBox(Model.ModelInstanceName + "_StreetAddress2", Model.StreetAddress2, New With {.style = "width:390px"})
                    @Html.ValidationMessageFor(Function(model) model.StreetAddress2)
                </div>
            </td>
        </tr>

<tr>
        <td>
            <div class="editor-label">
                <span class="required">@Html.LabelFor(Function(model) model.ZipCode)</span>
            </div>
            <div class="editor-field">
                @Html.TextBox(Model.ModelInstanceName + "_ZipCode", Model.ZipCode, New With {.style = "width:60px", .maxlength = "5", .onblur = "zipchange('" + Model.ModelInstanceName + "')"})
                @Html.ValidationMessageFor(Function(model) model.ZipCode)
            </div>
        </td>
        <td>
            <div class="editor-label">
                <span class="required">@Html.LabelFor(Function(model) model.City)</span>
            </div>
            <div class="editor-field">
                @Html.TextBox(Model.ModelInstanceName + "_City", Model.City, New With {.style = "width:130px"})
                @Html.ValidationMessageFor(Function(model) model.City)
            </div>
        </td>
    </tr>
</table>

依旧......

真正老的，但我遇到了同样的问题。有一篇简单的文章here解释了问题和解决方案。

你需要做的是这样的事情：

 @{ Html.Partial("AddressPartial", Model.Address, new ViewDataDictionary()
   {
       TemplateInfo = new TemplateInfo() { HtmlFieldPrefix = "Address1" }
   }); }

 @{ Html.Partial("AddressPartial", Model.Address, new ViewDataDictionary()
   {
       TemplateInfo = new TemplateInfo() { HtmlFieldPrefix = "Address2" }
   }); }

这将添加必要的前缀来控制id等，并在发回时正确绑定。（假设提供的前缀与您的属性名称匹配）

在页面上使用2个相同局部视图的实例
