问题 I have a form and it has tones of other controls(buttons, custom controls, labels, panel,gridview). You can guess i had flickering issue. I tried doublebuffering and it couldn't solve. Finally i tried this one: protected override CreateParams CreateParams { get { // Activate double buffering at the form level. All child controls will be double buffered as well. CreateParams cp = base.CreateParams; cp.ExStyle |= 0x02000000; // WS_EX_COMPOSITED return cp; } } Flickering gone but my datagridview

This is really annoying and may confuse the user. Here is some code to

I have an app that has a ton of controls on it. And it has a massive amount of flicker, particularly on startup. I applied this fix to it. protected override CreateParams CreateParams { get { CreateParams cp = base.CreateParams; cp.ExStyle |= 0x02000000; // WS_EX_COMPOSITED return cp; } } This worked great - the flickering was reduced by a pretty unbelievable amount.

This gives the app a hung feel. How
