I am trying to add a scroll viewer to stackpanels - "gradpaneldesc" , "undergrapaneldesc" and "certficatedesc" which are inside another parent stackpanel- "mainpanel" respectively, but I am unable to achieve this as its showing me scrollviewer perhaps but there is no actual scrollbar,not realizing where is the mistake. Any help will be highly appreciated.
