看这个我都快瞎了。当我点击视图上的save时,被发送到控制器的save方法的模型没有设置值,它们都是默认值。我错过了什么?实际上,我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,代码在控制器中输入SetSiteTerms方法,但没有来自视图的数据。: - (我知道这是一件简单而愚蠢的事情,但我只是还没有看到它。
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:我更新了视图和控制器。任何想法为什么我的模型被填充,可以在视图中编辑,但当我发布保存按钮,模型发送到控制器没有数据??
我已经更新了原始帖子,以显示Telerik提供的答案,同时我对模型其余部分的问题是一个愚蠢的缺失:lol
