Hi Ing.
I copied your GridView markup into the same sample in which I tested setting
the first column css display attribute to none and low and behold… I got the
same result that you got. But then I realized that the problem was simple.
I have turned one column display invisible but left its header visible. This
shifted the headers one column to the right. When I turned all columns that
were hidden to visible, I got all of your date formats displayed correctly.
I know it is a far shot but could it be that you have one column turned
invisible while its header is still visible. If it is not the case then you
might want to know that your code worked fine on my release version 2.0.50727
