Is there any way to have validation on particular Field while click on Button and bypass other required field.

I have tried it to make that field with some validation group and also the button with same group. But here this Button is validating all other Fields (which are configured as Required) as well. Though I don't want other field should be validated at this moment as I am using only buttonWidget instead of buttonWidgetSubmit. Other required field should be validated while clicking on buttonWidgetSubmit button only.
