我有使用 MVC 的项目，并且我有实例化服务的控制器，该服务管理存储库，并在存储库中进行 CRUD 操作。问题是，一旦我用我的服务中的数据填充我的网格控件（Telerik），如果我进行更新并刷新数据，它就会出现旧数据而不是新数据。我认为这是我的上下文变量的持久性问题，需要处理/实例化但不太确定何时何地（工作单元变量位于服务中）。

    <HttpPost()>
    <GridAction()>
    Function Edit(id As Integer, name As String, clientNo As String, image As String, unit As String) As ActionResult
        Try
            Dim org = Me._orgService.GetOrgById(id)

            With org
                .orgNAME = name
                .orgCLIENTNO = clientNo
                .orgIMAGE = image
                .orgUNIT = unit
            End With

            TryUpdateModel(org)
            Me._orgService.EditOrg(org)
        Catch ex As Exception
            'Log the error 
            ModelState.AddModelError("", MS_UNABLE_SAVE_CHANGES)
            Response.StatusCode = 500
            Return Content(String.Join("", (From state In ModelState Select state).SelectMany(Function(s) s.Value.Errors).Select(Function(e) e.ErrorMessage).ToArray()))
        End Try

        Return View(New GridModel(All()))

    End Function

这是服务

    Public Sub EditOrg(org As hdmtORG) Implements IOrgService.EditOrg
        Me._context.OrgRepository.Edit(org)
        Save()
    End Sub

这是存储库（通用）

    Public Overridable Sub Update(entity As TEntity) Implements IEntityRepository(Of TEntity).Edit
        Me._objectSet.Context.ObjectStateManager.ChangeObjectState(entity, EntityState.Modified)
    End Sub

任何的想法？

非常感谢。

尝试使用<OutputCache(Duration:=0)> _

<OutputCache(Duration:=0)>
<HttpPost()>
    <GridAction()>
    Function Edit(id As Integer, name As String, clientNo As String, image As String, unit As String) As ActionResult
