Hello Dariusz.
Thank you for writing.
RadGroupBox as every other control traverses its parents until it finds a parent with a explicitly set
Backcolor property. If such is not found, it will take it from the form since it is the last parent in the hierarchy of controls. Just like in your case, where the group box color is taken from the form, since the
RadPageViewPage and
RadPageView Backcolors are not explicitly set and they hold their default values.
If you want the group box to take the color from the
RadPageViewPage, simply set the group box
Backcolor to
Transparent:
However, there is an issue, with the design-time display - it is not refreshed correctly to show you the real backcolor. I have added this issue into our
Public Issue Tracking System. Please follow
this link in order to subscribe to its status updates and also to add your vote for it.
I have added 500
