System.Windows.Forms.DataGrid Performance

Hi, I use a System.Windows.Forms.DataGrid (.NET V1.0) as UI in a stock ticker program. Unfortunately, displaying data via the datagrid, grabs almost all performance available. When I minimize the ticker window CPU usage goes down to ~ 2% (data ist still retrieved and processed but not displayed). If I maximize the ticker window, CPU usage goes up to 50-100%. I'm updating the datacells by Datarow("Last price") = 9.99 This doesn't seem to be performable enough. Is there any other way to display data changes in a better way. Any comment is appretiated.
