two lines in the datagrid header Ok, this is a dirty workaround but it works. In a winform datagrid you can't directly change the columns header height. This is the workaround Eric, a collegue of mine find somewhere on internet : change the datagrid header font size without changing the column header font. for instance System.Drawing.Font f =new System.Drawing.Font("Verdana", 15.25F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point,Convert.ToByte(0)); MyDatagrid.HeaderFont = f;  ¶ 8:04 AM
