返回到控制器后，当模型属性未设置 [英] Model properties not set when returning to the controller for post

问题描述

我在这个失明盯着。当我点击视图保存，该模型被发送到控制器的保存方法没有设置值，他们都是默认值。
我在想什么？实际上，我用从其他项目完全相同的技术...
在我看来，将数据填充就好了，我可以编辑它，点击保存，code进入SetSiteTerms方法在控制器但现在没有从视图中的数据。 :-(
我知道这是一些简单和愚蠢的，但我就是不能看到它。

I'm going blind staring at this. When I click save on the view, the model being sent to the save method of the controller has no values set, they're all default values. What am I missing? I'm actually using the exact same technique from another project... The data is populated just fine in my view, I can edit it and click save, the code enters the SetSiteTerms method in the controller but has none of the data from the view. :-( I know this is something simple and dumb but I just can't see it yet.

型号：

Imports System.ComponentModel.DataAnnotations
Imports System.Runtime.Serialization

<KnownType(GetType(SiteToA))> _
Public Class SiteToA

    <ScaffoldColumn(False)> _
    Public Property ID As Integer = 0
    Public Property AgreementHTML As String = String.Empty
    Public Property AgreementName As String = String.Empty
    Public Property IsActive As Boolean = False

    Public Sub New()
        MyBase.New()
    End Sub
End Class

查看：

<%@ Control Language="VB" Inherits="System.Web.Mvc.ViewUserControl(Of Community_Portal_Admin.SiteToA)" %>
<% Using Html.BeginForm("SetSiteTerms", "SiteToA", FormMethod.Post, New With {.id = "SiteTermsForm"})%>


    <div class="gridFrame">
        <% Html.Telerik().EditorFor(Function(m) m.AgreementHTML) _
                    .Name("AgreementHTML") _ ' Name must be the same as the property name in the model
                    .Encode(True) _
                    .HtmlAttributes(New With {.style = "height:300px;"}) _
                    .Render()%>
        <br />
        <div class="smallFrameLeft">        
            <%: Html.ActionLink("Cancel", "Index", "Home", Nothing, New With {.class = "t-button", .Style = "font-size:12px;"})%>
        </div>
        <div class="smallFrameRight">
            <input type="submit" value="Save" class="t-button" />       
        </div>
    </div>
<% End Using%>

控制器：

Imports Telerik.Web.Mvc

Public Class SiteToAController
    Inherits System.Web.Mvc.Controller

    Function Index() As ActionResult
        Dim setting As SiteToA
        Try
            setting = SiteToARepository.One(Function(d) d.IsActive = True)
            ViewData.Model = setting
            Return PartialView()
        Catch ex As Exception
            Throw
        End Try
    End Function

    <HttpPost()> _
    Function SetSiteTerms(ByVal model As SiteToA) As ActionResult
        Dim setting As SiteToA
        Try
            setting = SiteToARepository.One(Function(d) d.ID = model.ID)
            TryUpdateModel(setting)
            If Not SiteToARepository.Update(setting) Then Throw New Exception("There was a problem during update")
            Return PartialView()
        Catch ex As Exception
            Return PartialView()
        Finally
            If Not setting Is Nothing Then
                setting.Dispose()
                setting = Nothing
            End If
        End Try
    End Function
End Class

编辑：
我已经更新了我的视图和控制器。为什么我的填充模型的任何想法，都可以在视图中编辑，但是当我用后保存按钮，发送到控制器的型号没有数据???

I've updated my view and controller. Any ideas why my model is populated, can be editing in the view but when I post with the save button, the model sent to the controller has no data???

推荐答案

我已经更新了原单后显示Telerik的所提供的答案，也是我与模型的其余问题是一个愚蠢的丢失：洛尔

I've updated the orginal post to show the answer provided by Telerik, also my problem with the rest of the model was a silly missing : lol
