How to improve painting performance of DataGridView?

Question

(sorry for bad English)

I have a big problem with performance of DataGridView when it re-paints.

I\'m using a DataGridVie

Answer 1

Clean Solution without reflection is:

public class DataGridViewDoubleBuffered : DataGridView
{
   public DataGridViewDoubleBuffered()
   {
       DoubleBuffered = true;
   }
}

Then go to myForm.designer.cs and change a type from DataGridView to DataGridViewDoubleBuffered .
