Hi Jesse,
thanks for your suggestion. However, your solution doesn't work because this app support RTL languages such as arabic. If you applied the code, it will not work for English or other LTR languages. I only have single .XAML files for all
26 supported languages. The UI are flipped based on the flowdirection in the code, and it gets the "RightToLeft" in the resource file that has a flag.
If there anyway to externalize the \ue0ac to .resw? Currenly, if i do that, rather than showing the Symbol, it shows \ue0ac.
By the way, the ArrowGlyph is under StandardStyles.xaml provided by Microsoft and it doesn't contain the <button element.
<TextBlock x:name="ArrowGlyph" Text=""...etc
If i changed to
<TextBlock x:name="ArrowGlyph" x:UID:"RTL_Arrow"...etc.
Under arabic.resw:
RTL_Arrow= 
This doesn't work.
thanks
-James
