如何将WebGrid行的全部内容传递给MVC中的Controller

Question

我正在用数据库查询中的一些项目数据填充WebGrid。此WebGrid上的一列是复选框列。一旦单击“获取行”按钮，从而提交了表单，我便能够使用选中的复选框获取FormCollection。我的问题是如何获取与复选框关联的item_id和item_desc单元格？

控制器操作1：

Public Function ShowGridView_ListOfItems() As ActionResult
            Try
                Dim adapter As SqlDataAdapter
                Dim ds As New DataSet
                Dim con As SqlConnection
                Dim con_string As String
                con_string = "Data Source=localhost;Initial Catalog=[db];User Id=[ID];Password=[pass]"
                con = New SqlConnection(con_string)
                con.Open()
                adapter = New SqlDataAdapter("select item_id, item_desc from inv_mast", con)
                adapter.Fill(ds)
                con.Close()

                Dim objList As New List(Of Object)
                objList = Rule.GetDatatableAsList(ds.Tables(0))

                Return View("GridView_ListOfItems", objList)
            Catch ex As Exception
                Return View("Error", New HandleErrorInfo(ex, "GridView", "GridView"))
            End Try
        End Function

查看：

@ModelType System.Collections.Generic.IEnumerable(Of Object)
@Code
    ViewData("Title") = "GridView_ListOfItems"
    Layout = "~/Views/Shared/_VisualRuleLayout.vbhtml"
End Code

<link href="~/Content/bootstrap.css" rel="stylesheet" />

@Using Html.BeginForm("GetGridViewRows", "GridView", FormMethod.Post)
    @<text>
        <div Class="form-horizontal">
            <form>
                <h3>Items</h3>
                @Code
                    Dim grid = New WebGrid(Model, canPage:=True, canSort:=True, rowsPerPage:=10)
                    grid.Pager(WebGridPagerModes.NextPrevious)
                End Code
                <div>

                    @Code
                        @grid.GetHtml(htmlAttributes:=New With {.id = 
"grid", .class = "table table-bordered table-striped table-condensed", .name 
= "grid1"},
emptyRowCellValue:="No Records Found",
headerStyle:="grid-header",
columns:=grid.Columns(
grid.Column(header:="Select", format:=Function() Html.CheckBox("chkboxname", 
htmlAttributes:=New With {.id = "chkbox1", .value = "chkVal"})),
grid.Column("item_id", "Item ID"),
grid.Column("item_desc", "Description")))
                    End Code
                </div>


                <Button Class="btn btn-warning pull-right" type="submit">Get Rows<i class="glyphicon glyphicon-arrow-right"></i></Button>
        </form>
    </div>
</text>
                    End Using

控制器操作2：

Public Function GetGridViewRows(ByVal gridViewRows As FormCollection)
            Dim checkedResults = gridViewRows.GetValues("chkboxname")
            Dim results
            If Not checkedResults Is Nothing Then
                For Each value In checkedResults
                    If Not value = "false" Then
                        results += "(" & value & ")"
                    End If
                Next
            End If
            ViewData("Message") = results
            Return View("~/Views/MessageBox/MessageBoxOK.vbhtml")
        End Function
