Why 3 reasons? It looks like a joke. Pick one. Multiple choices make people unhappy. Creating problems where there shouldn't be any. And a "reason" for what? Sleeping in?

Hello ...Thank you for your response but kindly don't judge before knowing full...in our process the product might get rejected for variety of reasons , and a single product can contain up to three defects ..hence three combo box are needed to fill in the data for the three columns sometimes it will one or two or three or nil based on the product status. Any idea how to do it?

You show no code. If they all "act" the same, then your bindings "are the same". How is anybody on this end able to "see" that? And if you can have "3+ rejection issues", you've got a quality assurance problem and your "3 reasons" won't help.

Hi just make the data source of combobox using the data table clone method.
This will assign separate data source to each combobox.
