主题：请问如何对findrow到的行进行操作

AfterCheckRow事件

Dim d As Row =e.Table.Current

If d.Isnull("识别码") = False Then
    Dim th As String = d("识别码")
    Dim idx As Integer = -1
    Do While True
        idx = Tables("窗口1_Table1").FindRow("识别码 = '" & th & "'", idx+1, False)
        If idx > -1 Then
            Tables("窗口1_Table1").Rows(idx).Checked = d.Checked
        Else
            Exit Do
        End If
    Loop
End If

Dim sum As Single
For Each r As Row In Tables("窗口1_table1").GetCheckedRows
    sum += r("数量")
    e.Form.Controls("合计").Text = sum
Next
