I am setting some of the headers etc. in the grid based on a resource file to match current user's culture/language. I am also automatically calculating the size of columns and setting the row selector size to 20px. When I use default resource all works fine, but when I switch to a non-default resource the row selector's size is always equal to column's size, even though it's size is always set to 20px. The additional column which appears when a row has child grids (btw. how can I hide this column without loosing "outlook group by" functionality?) also has the same size (which is correct for default resource file). Is there any quick-fix for this?
