Multi select combobox with checkbox generic control in wpf

问题

I want to create control which will allow user to select multiple selections from dropdown using check box.I have searched on Google and I got some links like

http://code.msdn.microsoft.com/windowsapps/Multi-Select-ComboBox-in-cfbf1e22/view/SourceCode#content.

I found this article useful but I can not use this control in every application because ItemsSource type may change in every application. I want to create generic control which will be used by any application which may have different ItemsSource. How do I create generic control which can be used in any application?I want to create DLL for this control and want to use it in all applications.

                <Setter.Value>

                        <CheckBox>
                            <ContentPresenter />
                        </CheckBox>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
