Hi Theone,

Forcing that many repaints is going to be quite expensive. Would it not be a better idea to save the data for the list, but only refresh the DataGrid once every second or something? (ideally you would want to specify the frequency).

Reloading a DataGridView (or any control on a form) thousands of times a second is not only likely to create an epilepsy inducing screen flicker but likely bring most PCs to a grinding halt.

Like Rob says, storing up the changes and refreshing the grid every second (or even longer) would be a much better way to go.
