主题：如何实现以下功能？谢谢

在表B的录入窗口中，直接根据目录树选择“组”后，“村”、“乡镇”控件内自行填入相应的值！！！

If e.Node.Level = 0 Then
    Dim Vals() As String = e.Node.FullPath.Split("\")
    Dim Filter As String = "[乡镇] = '" & Vals(0) & "' "
    Tables("表A").Position = Tables("表A").findRow(Filter,0,False)
ElseIf e.Node.Level = 1 Then
    Dim Vals() As String = e.Node.FullPath.Split("\")
    Dim Filter As String = "[村] = '" & Vals(0) & "'and [组] = '" & Vals(1) & "' "
    Tables("表A").Position = Tables("表A").findRow(Filter,0,False)
ElseIf e.Node.Level = 2 Then
    Dim Vals() As String = e.Node.FullPath.Split("\")
    Dim Filter As String = "[乡镇] = '" & Vals(0) & "'and [村] = '" & Vals(1) & "' and [组] = '" & Vals(2) & "' "
   
Dim Vals1() As String = e.Node.FullPath.Split("\")
Dim frm As WinForm.Form = Forms("基础信息录入窗口")
If frm.Opened
Dim xz As WinForm.TextBox = Forms("基础信息录入窗口").Controls("乡镇")
Dim cz As WinForm.TextBox = Forms("基础信息录入窗口").Controls("村")
Dim zb As WinForm.TextBox = Forms("基础信息录入窗口").Controls("组")
   xz.Value = vals(0)
   If vals1.Length > 0 Then
      cz.Value = vals(1)
  End If
   If vals1.Length > 1 Then
      zb.Value = vals(2)
  End If
End If
e.Form.Close()

End If

这样加进去就可以了

由于控件未绑定表，如何将这些未绑定表的控件内的数据保存到表相应的行和列内？

谢谢
