For some reason the above mentioned event is never called for top text that i want to set for the thumbnail. I did set DefaultTopText to iedtCustom, just if it matters...I did also set SortOrder to iesbTopText.
The whole idea is to use the top text for sorting in a scenario when the user can drag and drop the files within the control to change its position. So i want to use drop event to update toptexts for all the thumbnails so it will be displayed in a new order.
Is there a better way to achieve the above mentioned functionality? I would appreciate any advice.
