Hi Hans,
Thank you for the description and screenshot.
I was only able to reproduce the described behavior by setting the
Background property directly to the control. Because a local value has a higher priority, the
Style Trigger is ignored. Could you check if somewhere in the project the
Background is set either in the
XAML or in code-behind? If not, please send me a project that shows the behavior, so I can investigate further.
In the sample project, the reason why there is a difference between the shown color and the one in the properties window is because when the
RadMultiColumnComboBox is disabled, the
SearchAutoComplete's opacity is set to 0.6. By
editing the control template for
RadMultiColumnComboBox, the opacity can be reset or modified in the trigger for the control's disabled state:
Attached, you can find the updated sample project in which I've demonstrated this approach.
