how to align column header using datagrid view control

To center the column header text, you can do:

dataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

To set all the columns to the same width, I think you'll have to set them individually as I can't find a property to do this 'en bloc'.

thanks for your reply but I didnt get HorizontalAlign="Center" in HeaderStyle and ItemStyle

Can you please answer it specifically for datagrid view? and wherethese settings are??
