We have tried with standard panel with background image ; it works.but,rendering slowly which is frustrating our customers.Now,again we used Panel control of DevEx with Appearance.Image property.but,it does not set the background image.please guide us where we missed out?.we have attached screen to explain clearly.
Please set your LookAndFeel Style property to non-skin value, and the UseDefaultLookAndFeel to False. I've attached a sample.
Let me know if you need further assistance.
Thank you, Marina
