Window taking long time to display

I am developing a windows application, i designed a window which contains about 11 containers on it.
Now the problem when i call this window it takes long time to open, about 1 minute.
When opens this window open event of every container get fired that results in long time.

Can any one tell how can minimize the opening time of window ?

I’ve not seen such an extreme slow down in default Open events on windows in Windows, so I’d assume that your Open events are doing work that is taking time. In most cases this is handled by using a splash screen to display while the work is being completed, then the splash screen is hidden when the primary window is ready.

Do you have a thread running in a tight loop?
