主题：提交条件与提交后隐藏成功提交的相关行

For Each r As Row In Tables("订单").GetCheckedRows
    If r.IsNull("订单编号") = False
        Dim Filter = "[订单编号] = '" & r("订单编号") & "'"
        Dim dr As DataRow = DataTables("配载订单").sqlFind(filter)

我想在这加另外一条提交前的条件,类似于

Dim Filter = "[项目] = '" & r("项目") & "'"
        Dim dr As DataRow = DataTables("项目信息").sqlFind(filter)

意思是"订单"的项目必须是表"项目信息"里有的并且"配载订单"的订单编号没有重复的才能提交到"配载订单"

然后满足这些条件的订单提交后隐藏(但可以刷新重新显示) 是为了可以快速分清不满足条件的行 好做其他操作

        If dr Is Nothing Then
            ls.Add(r)
            count += 1
        Else
            dic.add(dr, r)
        End If
    End If
Next

Dim p As WinForm.ProgressBar
p = e.Form.Controls("ProgressBar1")
If ls.count > 0 Then
    p.Visible = True
    p.Maximum =  ls.Count - 1 '设置最大值
    p.Minimum = 0 '设置最小值
    p.Value = 0 '设置当前值
End If
Dim idx As Integer = 0
DataTables("订单").StopRedraw
For Each r As Row In ls
    Dim dr As DataRow = DataTables("配载订单").AddNew
    For i As Integer = 0 To Cols1.Length -1
        If r.IsNull(Cols1(i)) Then
            dr(Cols2(i)) = Nothing
        Else
            dr(Cols2(i)) = r(Cols1(i))
           
        End If
       
    Next
    idx += 1
    p.Value = idx
Next
For Each key As DataRow In dic.Keys
    Dim r As Row = dic(key)
    Dim dr As DataRow = key
    For i As Integer = 0 To Cols1.Length -1
        If r.IsNull(Cols1(i)) Then
            dr(Cols2(i)) = Nothing
        Else
            dr(Cols2(i)) = r(Cols1(i))
        End If
    Next
Next
