[Bug]: Can not "Control / Set Disabled" Background Colour Of Comboboxes, in DropDown mode

[MattH-Work]

All of the comboxes in the attached image are using the DropDownStyle "DropDownList" and behave as expected
I am overriding the Back colour for both StateCommon & StateDisabled to be LightYellow

The Description combobox is using DropDownStyle "DropDown" and as you can see has the LightYellow backround (again I am overriding both StateCommon & StateDisabled)

BUT...

Where has the Grey box come from?
Is this a bug, or do I need to override soemthing else?

I find the same issue with any combobox using DropDownStyle "DropDown"

Note, the Groupbox that hosts all the controls is currently disabled (Enabled = False), when enabled ALL comboxes display as expected

Cheers

Trying to remember of the top of my head, but when in "DropDown" then there is an edit component, therefore it will also need to be overridden.
If you can wait, I can check at the weekend.

I can wait

Thanks for the help

Grey box is also being applied to the KRTF in the disabled state:

It gets worse..

This is turning me in circles..
I think that each ToolBox Item should be separated into new issues; Then focus on each in turn. (It also means I can the restart the whole process !)

@MattH-Work @Wagnerp
As you can see, I have refocused this item, and added 2 new ones for the other types that "Do not work"
I can now refocus and restart this with the Current Alpha codebase ;-)

Sorted:

PR coming soon.
