You need tag the application type or the library you use. WPF? Forms? Silverlight? ASP.NET? Metro? What?

Solution 1

As a general suggestion, enclose your painting/updating logic inside a Control.BeginUpdate() and Control.EndUpdate() block, it would reduce your flickering to a great extent. If you are still not satisfied, you can enable DoubleBuffering.

This is a valid and potentially effective suggestion, but it only applicable to some UI libraries, like System.Windows.Forms. Too bad OP did not specify it, but this is not your fault, therefore I voted 5.

The link he posted has reference to UserControls, therefore I assumed he is talking about WinForms, he could have been clearer though.

I used simple trick is to use timer to show the form hidden after some timer i increase the visibilty to fully show the form, showing the form at once make it harder to be rendered,

when i Load the form i set the Opacity = 0; and i enabled a timer, on timer tick
Opacity += 0.05 when the opacity ==1 i disable the timer.
