I would like to show that a datagridview record has been processed by changing the row forecolor, but to speed up the processing I don't want to redisplay the entire datagridview, just the modified row. Is this possible? I can't change the color of the datatable row that is my datasource, and anything else I try seems to require refreshing the entire grid and all its formatting. These are large grids and rewriting them is slowing my code.
