主题：[求助]“窗口中的动态列表项目”能不能设计成“复选组合框”

Dim cmb As WinForm.ComboBox = e.form.Controls("ComboBox1")
cmb.ComboList = DataTables("表A").GetComboListString("型号")

2、在ComboBox2的Enter事件中加入代码：

Dim cmb As WinForm.ComboBox = e.Sender
Dim str As string = e.Form.Controls("ComboBox1").Value
cmb.ComboList = DataTables("表A").GetComboListString("规格", "型号 = '" & str & "'")

3、最后在ComboBox3的Enter事件中加入代码：

Dim cmb As WinForm.ComboBox = e.Sender
Dim str As String = e.Form.Controls("ComboBox2").Value
cmb.ComboList = DataTables("表A").GetComboListString("颜色", "规格 = '" & str & "'")

请问：这个能不能设计成“复选组合框”。
