C#

using DevExpress.Utils;
// ...
((RatingContextButton)pictureEdit1.Properties.ContextButtons[0]).Enabled = false;
pictureEdit1.Properties.ContextButtonOptions.DisabledStateOpacity = 0.5f;

VB.NET

Imports DevExpress.Utils
' ...
CType(pictureEdit1.Properties.ContextButtons(0), RatingContextButton).Enabled = False
pictureEdit1.Properties.ContextButtonOptions.DisabledStateOpacity = 0.5F

The image below demonstrates the result.

Alternatively, you can set the DisabledStateProperty value in a control’s Properties window.
