返回控制器进行发布时未设置模型属性
看着这个我都要瞎了当我在视图上单击“保存”时,发送到控制器的保存方法的模型没有设置任何值,它们都是默认值。 我缺少什么?我实际上正在使用另一个项目中完全相同的技术...... 数据在我的视图中填充得很好,我可以编辑它并单击保存,代码进入控制器中的 SetSiteTerms 方法,但没有视图中的任何数据。 :-( 我知道这是简单而愚蠢的事情,但我只是还看不到它。
模型:
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
视图:
<%@ 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。为什么填充我的模型的任何想法都可以在视图中进行编辑,但是当我使用保存按钮发布时,发送到控制器的模型没有数据???
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.
Model:
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
View:
<%@ 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%>
Controller:
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
EDIT:
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???

我已经更新了原始帖子以显示 Telerik 提供的答案,而且我对模型其余部分的问题是一个愚蠢的缺失:哈哈
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
