Hi Matt,

Thanks for the quick reply. We are listening to a datasource for update. So it's not easy to batch the update unless we add throttling into our datasource. I am just wondering whether there is a way to suppress grid's repaint so we can just make force repaint periodically. I set BindingSource.RaiseListChangedEvents = false but grid is still updating/repainting itself.

 Simon,

I meant that you wrap the updates in a BeginUpdate/EndUpdate, unless you are just getting each update one-at-a-time and you have no way of combining them into batch updates.  I can't really say when the best places to do this is since I don't know how you're updating the grid, but it'd be something like:

grid.BeginUpdate();

dataSource.Rows[0].Cells[3].Value = "Some New Value";

dataSource.Rows[1].Cells[2].Value = "Happy Happy, Joy Joy";

grid.EndUpdate();

Hi Matt,

 Thanks for your reply. We are still on 7.1. How can we wrap painting in BeginUpdate/EndUpdate block? We are using BindingSource so the grid update itself whenever datasource changes. I suppose you mean there is a way that I can suppress grid from repaint itself, then I can batch the updates. Can you give me more details on that?

 Thanks.
