about datagrid, anybody here how to solve these:

1. remove bold in datagrid header and cell
2. header text alignment in datagrid
3. change header font in datagrid
4. getting the sum in cells

in design time i set the font to normal, but when i run it shows bold font both header and cell is this a bug?
(the only i did is hide some columns in the datagrid)

tnx...
