This is what google asked me to put on the sitemap feature
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. is is the workaroun Eric, a collegue of mine find somewhere on internet : change the datagrid header font size without changing the column header font.
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;
