Hi Leon,


You can able to change or disable the background of the ComboBoxAdv while mouseover by overriding its Control template. We have created a sample based on your requirement. Please refer to the sample for your reference.

I implemented the code and changed it a bit so that its good for me. It works perfectly except for one little thing. When I keep the ComboBoxAdv pressed after it closed there is still this blue selected color as you see on the image.

You can disable the blue background while pressing the ComboBoxAdv by removing RenderPressed property for the Buttonchrome in toggle button
