主题：listview不显示数据

Dim lvw As WinForm.ListView = e.Form.Controls("ListView1")

lvw.Images.Clear()

lvw.Rows.Clear()

For Each dr As DataRow In DataTables("成都寰球").DataRows

    Dim vr As WinForm.ListViewRow = lvw.Rows.Add()

    For Each cl As WinForm.ListViewColumn In lvw.Columns

        vr(cl.Name) = dr(cl.Name)
