Answer 2

In the constructor of your control, set the DoubleBuffered property, and/or ControlStyle appropriately.

For example, I have a simple DoubleBufferedPanel whose constructor is the following:

this.DoubleBuffered = true;
this.SetStyle(ControlStyles.UserPaint | 
              ControlStyles.AllPaintingInWmPaint |
              ControlStyles.ResizeRedraw |
              ControlStyles.ContainerControl |
              ControlStyles.OptimizedDoubleBuffer |
              ControlStyles.SupportsTransparentBackColor
              , true);

Answer 3

Use the DoubleBuffered property, inherited from the System.Windows.Forms.Control.

System.Windows.Forms.Form myForm = new System.Windows.forms.Form();
myForm.DoubleBuffered = true;
