How do I remove the grey background from the combobox?

I am having trouble styling a ComboBox. I have given a link to a screenshot that shows a ComboBox next to some TextBlock controls. When the ComboBox is not selected, I want it to look like the TextBlock controls, but I can't seem to find the property to get rid of the default grey background.

Any help would be most appreciated.

What I have tried:

I have tried the Background property and have looked through all the properties on MSDN (though I haven't yet worked my way up the class hierarchy to see if I can see the property causing the problem).

Thank you for that link. Jeez... could it be any more complicated? That seems like a monstrous amount of work to change a single property of the standard ComboBox. Is there any way to get a copy of the in-built control, so I could just change the bit I want?

I was not able to see the link here at my location due to restrictions; however, from what I understand is when you are not selecting the combobox, you would like the style to look more like a textblock. The link that NotPolitcallyCorrect posted is the documentation on how a combobox is created from scratch; however you can change it without that much work. I would however create a control template in a resource dictionary that targets combobox. Then I would add a trigger on the control template that fires when the combobox does not have focus that changes the style of the template to look like a textblock.

Right click on the combobox go to properties and change the BackColor property to whichever color you want.

I guess I'm being thick here, but I can't seem to find any setting that changes the default grey colour.
