According to the attached picture, it seems that you have CommandBarDropDownButton in RadCommandBar and RightToLeft = True. I was able to observe the same issue with the arrows in the Office2010Black theme. This is why. I have logged it in our feedback portal by making this thread public. You can track its progress, subscribe for status changes, and add your comments on the following link - feedback item.
Currently, you can change the position of the arrows by using the AngleTransform property. Please refer to the following code snippet:
' This call is required by the designer.
Me.CommandBarDropDownButton1.RightToLeft = TrueDim item1 = New RadMenuItem("Item 1")
Dim item2 = New RadMenuItem("Item 2")
Dim item3 = New RadMenuItem("Item 3")
Dim item4 = New RadMenuItem("Item 4")
Dim item5 = New RadMenuItem("Item 5")
item3.Layout.ArrowPrimitive.AngleTransform = 180
item2.Layout.ArrowPrimitive.AngleTransform = 180EndSubEndClass
The following picture illustrates the result when using the specified Office2010Black theme:
I hope this helps. Should you have other questions please let me know.
