Control Flicker while switching TabPage

[Ingo Beyer]

Hello,

I created a windows form with vs.net 2005 / c#. This control has a
TabControl with 16 TabPages. On every TabPage there are a diffrent number of
Controls. - Every TabPage has a background picture. they are all the same
picture (from a resouce file). There seems to be no way easy to make a
TabControl transparent...

my problem: while switch the visible TabPage the form / TabControl begans to
flicker. it takes a second (and I mead "1 sec") before all controls of the
TabPage are drawed. I can see, who one control after another appears. -
while switching there is only standard code executed, no code written by me.

has anybody an idea how to remove the flicker?

thank you

Hi Ingo,
im also facing the same issue,
but i have used user controls in my tab pages, and the best part is i
ve tried using normal controls also, still same,
even with data access code running its the same performance, all the
controls are drawnone by one like a card stack falling. looks nice.
perhaps someone could suggest an improvement?
what i found most surprising is that the sequential drawing shows same
performance even at runtime with all my 18 combo boxes being populated
from th database.
and please dont suggest a displa card upgrade.
thanx in advance,
Amal
