Hi Sopheap Ly,
I must agree that we never made tests with Asian languages under Vista.
Under Windows XP the buttons seem equal (see
Buttons_XP.png) so when we made the tests we decided that the visualization is correct.
We have our reasons to use
DrawString() instead of
DrawText() - there are problems with the painted text when
DrawText() is used. As this issue comes to our attention now, we will
consider modifications in the painting code.
Thank you for helping us to improve the painting of non-english languages. Please, excuse us for the inconvenience caused. We have updated your Telerik points for the suggestions. Don't hesitate to contact us if you have other questions.
Regards,
Angel
the Telerik team
