Hello,
I am making an application in vb.net 2012.
I have used split container, table layout panel and panels as container in my form.
I also have buttons, text boxes, tool strip,status strip,combo box, list view etc
the problem is when i load the form it flickers a lot. also when the list view columns width is changed while populating the list view it flickers and which doesn't look good. I have tried few solutions
1) i have set double buffered property to true
2) no container back color is transparent
3) to prevent flicker while loading i used suspendlayout() and resumelayout()

But it just reduced flicker a bit, its not completely gone.

Note: I have added images in table layout

if you have many controls with a transparent background then your going to see flicker. you have taken the right steps although there is one more. look into the onPaint event as this is called last.

Hope this helps

thanks Kevin,

I have not added Paint event in my code anywhere,
so could you elaborate what should i try exactly.

I cannot offer a better solution using WinForms, but I highly recommend WPF. It takes a little getting used to - and yet it will amaze you! Oh and you can do everything your wanting with it. Controls with transparency is one of it's specialties. I think am pretty much done with WinForms. Don't worry we have a forum for WPF here too!
