SuspendLayout Not Suspending...

[Guest]

I have a user control (tag) made up up 9 smaller user controls (minitag).

I have a panel on a form that is being populated with 81 of the tag controls in a grid configuration.

Even though I am using Suspend Layout, I still see the controls getting drawn as they are added to the panel.

I've tried suspending the layout of the form, of the panel and even on the user controls.

How can I get this thing populated wihtout seeing it being drawn so slowly on the screen?

Thanks.

If you are using version 2 of the Framework, you can set to true the
property DoubleBuffered of the Form or Panel.

DoubleBuffered reduces the flickering, but it has not effect on the controls
being drawn slowly.

Hi,

I am sorry that I could not understand your scenario exactly.

What's the kind of your application, a WinForms or Web application?

I have a user control (tag) made up up 9 smaller user controls (minitag).

I have a panel on a form that is being populated with 81 of the tag
controls in a grid configuration.

What's the "tag controls" in the above sentence?

If possible, could you please send me a sample project that could just
demonstrate your problem? To get my actual email address, remove 'online'
from my displayed email address.

Only if I understand your problem exactly, I may provide possible
assistance to you.

Thank you for your understanding and cooperation!

Sincerely,
Linda Liu

Linda,

It's a WinForm application. And the "Tag" control is a user control within
my project.

Picture a 9 x9 grid of squares (I called them tags). Each square has a
small 3x3 grid of mini tags within it.

I'm using 3 types of user controls to create each "tag". A "minitag", a
"minitagpanel" which is made up of 9 minitags. And a "tag" which contains a
minitagpanel. Then I add 81 "tags" to the controls collection of the panel
on the form. There's also some custom graphics getting drawn on the panel
behind the user controls.

I guess I just need to know the best way to handle the drawing, etc.
because it's all really slow.

I can send you the project if this is not enough info.

Hi J,

Thank you for your prompt response.

I understand your problem now. However, I'd like your sample project to see
how slow the usercontrols are drawn on the form. Could you please send it
to me?
