如果为列名指定Select New with()，则Gridview不允许编辑

Question

当我在vb.net中使用以下内容将数据绑定到网格视图时，它工作正常，可以编辑单元格，但当我声明列名时，它不允许我编辑单元格值

    Dim bs As New BindingSource

    bs.DataSource = (From u In threeContext.dbContext.skechersDeliveries Where u.isprocessed = False Select u)
    bs.ResetBindings(True)
    dgDeliverys.DataSource = bs

这是一个例子我会如何删除列名而不是slect u我会在下面有一些谎言

       Select New With
            {
             Leave.Id,
            Leave.Leave_Month,
             Leave.Leave_App_Date,
            Leave.Leave_From_Date, Leave.Leave_To_Date, Emp.EmplName, Leavetype.LeaveDesc, Leave.Leave_Day
            }

我正在使用以下选择

订单号将bs Dim为新绑定源

    Dim cfglocation As Int16
    cfglocation = cfb.StoreLocation
    bs.DataSource = (From u In threeContext.dbContext.R3Delivery Where u.isprocessed = False AndAlso u.location = cfglocation
                    Select OrderNumber = u.ordernumber, BarCode = u.tagbarcode, Qty = u.qty, Processed = u.isprocessed, NotDelivered = u.isDelivered)


    bs.ResetBindings(True)
    dgDeliverys.DataSource = bs
    dgDeliverys.Columns(0).ReadOnly = True
    dgDeliverys.Columns(1).ReadOnly = True
    dgDeliverys.Columns(2).ReadOnly =true

第三列是qtry，当你看到它们的i停在2时，它应该是可以更改的，但当我声明上面的列名时，我不能再双击并直接编辑数据网格

我认为你应该。。。。

Dim bs As New BindingSource

bs.DataSource = (From u In threeContext.dbContext.skechersDeliveries 
                 Where u.isprocessed = False 
                 Select New With{.ID = u.FieldThatMapsToID,
                                 .LeaveMonth = u.FieldThatMapsToLeaveMonth,
                                 .......
                                 .Leave_Day = u.FieldThatMapsToLeave_Day})
bs.ResetBindings(True)
dgDeliverys.DataSource = bs
