You need to register skins. Typically, when you launch an application, you use an extensive application shell.
See the article in the DevExpress online interface documentation .
Here is what I usually do:
DevExpress.UserSkins.BonusSkins.Register();
DevExpress.UserSkins.OfficeSkins.Register();
You will need to add links to DLE DevExpress Skin files. And after that you can just use the skin you need:
defaultLookAndFeel1.LookAndFeel.SetSkinStyle("Office 2010 Silver");
defaultLookAndFeel1 - , WinForm. . , Look and Feel.
Update:
DevExpress . .
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
DevExpress.UserSkins.BonusSkins.Register();
DevExpress.Skins.SkinManager.EnableFormSkins();
DevExpress.Skins.SkinManager.EnableMdiFormSkins();
