How do I stop the datagridview from violently repainting when a user clicks on a cell that was not initially visible?

原文 2012-03-06 17:21:34 2 1 c#/ datagridview

I have a datagridview that is horizontally large. A good portion of it must be scrolled to in order for the user to see it. Curiously, whenever someone first clicks on a cell that wasn't in the group of 'originally visible cells', the datagridview decides to repaint itself. This might not have been a huge problem, but for this datagridview the repainting is really slow and noticeable.

The second click and all subsequent clicks on a particular cell will not cause the repaint.

Does anyone know how to calm the datagridview down?

Thanks!

To fix this, I just had to add DoubleBuffered = true to the constructor of my subclassed Datagridview.
