Suspending screen updates

[John]

Hi

I have a winform with a panel on it. I am doing visual changes to the panel.
Is there a way to suspend screen painting during these changes? If the whole
form needs its display suspended then that would work for me too. How can I
do this?

Thanks

Regards

You'll get the best solution if you tell us why you want to do this. Do
you do a lot of visual changes and do you want to speed it up? How long
does it currently take? What kind of changes?

Hi Armin

I am adding several controls to the panel and would like to display them all
at once when the update is complete.

Many thanks for your time.

Can you hide the whole panel before and show it afterwards? Maybe show
an additional "please wait..." label (or similar) during the operation.

? (just to receive an impression)

John,

Those controls where this makes sense have properties for this.

Have a look at the listview by instance.
