I have one DataGridView and want to make the Header text Bold.
I have tried changing the ColumnHeaderDefaultCellStyle to
DataGridViewCellStyle { BackColor=Color [Control], SelectionBackColor=Color [Highlight], SelectionForeColor=Color [HighlightText], Font=[Font: Name=Tahoma, Size=9.75, Units=3, GdiCharSet=0, GdiVerticalFont=False], WrapMode=True, Alignment=MiddleCenter }

In the designer I can see the Headers as Bold but at runtime it shows as normal.
Please not that apart from ColumnHeaderDefaultCellStyle I am also changing
DefaultCellStyle of DataGridView as well as of Individual Columns.

How to make the headers bold ?

    Suppose you want to change the style of column 0 of DataGridView myDataGrid:

    myDataGrid.Columns[0].HeaderCell.Style.Font = new Font("Tahoma", 9.75F, FontStyle.Bold);

    If you want to change the default for headers:

    myDataGrid.ColumnHeadersDefaultCellStyle.Font = new Font("Tahoma", 9.75F, FontStyle.Bold);

    EDIT:

    In the designer you can click on the properties box of the control, click on the small box beside ColumnHeadersDefaultCellStyle property, expand Font and set Bold=True:
