Publishing a WPF application with DatePicker

Question

I developed a  application which contains wpftoolkit's datetimepicker control in it,  i can publish the application but it is working only with systems where wpf-toolkit is installed, and a XAML-PARSE error is thrown when installed in systems witout wpftoolkit.
I  want to know how to add wpftoolkit components while publishing the application so that while installing the application it installs all the components required for wpftoolkit controls to work..
