Its probably that you might be painting something in your form...

You need to enabled the DoubleBuffered property of the control to reduce flickering...

And in Panel you won't find such a property so.. you need to create a custom Panel...

Create a custom Panel Contol (Custom Control)
and put this code in the panel constructor

            this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
                this.UpdateStyles();

You're asking everyone to make a lot of assumptions and guesswork about your code. Please provide the code you are using for the constructor and the on_load event handler, so we can actually see what you are doing when the form is created and shown.

I already done this, but it does not reslove my problem.can you give me a another suggestion for this?

@vikram rawat
check your code in OnPaint() method ...

You might be calling Invalidate() method inside OnPaint()..

can you post your code

The other option might be that you're just trying to draw too much in your paint method. GDI+ isn't known for its speed so if this is the case you might need to explore other drawing options.

That said, I'm with T and ThatThatGuy here. You need to either post some code or be more descriptive of what you're trying to do and what's going on.

@vikram rawat
When using GDI+ Painting you need to be smart enough in handling all painting and drawing activities..

BCoz if you don't then GDI can really be a headbump

OP doesn't want to provide code so we can actually help.
