Flickering issue in Windows Forms

Question

I have a problem with flickering on my controls. I have Drag and drop operation, and when dragging a control, it is flickering. How can I solve it ? I tried this

 public Form1()
    {
        InitializeComponent();
        .
        .
        .
        this.DoubleBuffered = true;
    }

But did not worked for me. How can I fix it ?

What kind of controls are flickering? You included a user-controls tag. Your DoubleBuffered setting is only for the form, not the controls. — LarsTech, Apr 03 '14 at 15:16

It's a method you call in your form's constructor or OnLoad method (Load event). — LarsTech, Apr 03 '14 at 15:31

public static void SetDoubleBuffered(System.Windows.Forms.Control c)
{
   //Taxes: Remote Desktop Connection and painting

   if (System.Windows.Forms.SystemInformation.TerminalServerSession)
      return;

   System.Reflection.PropertyInfo aProp = 
         typeof(System.Windows.Forms.Control).GetProperty(
               "DoubleBuffered", 
               System.Reflection.BindingFlags.NonPublic | 
               System.Reflection.BindingFlags.Instance);

   aProp.SetValue(c, true, null); 
}

This method helps a lot.
