Thank you Steve Jowett, OK. It is a good idea. But I have a little problem. My experience in VS User Control construction is very poor. So I'm looking for something already done. A VB or C# User Control that I can downloaded and put in my forms. Thanks

Thank you Kevin, Because I want a control that open a dropdown list when got the focus, and close it when lost the focus like a Combobox, but accepted more than one selection like a Listbox control.

Hi All, I need a control that work like a Combobox, but accepted more than one selection like a Listbox control. Someone help me? Thanks,
