Hosting Windows Forms Controls in v1.2

Jun 11, 2009 at 6:18 PM

I am not sure if anyone else is having this problem, but after upgrading to v1.2 in my application the loading and resizing of documents that host windows forms controls has become very slow. It takes approxx. 3-4seconds to open a document that hosts a windows forms control, or even switch to a different document that hosts a windows forms control.

It is possible that something else is causing this delay, but there are some documents in my app that do not host windows forms controls and they load up & switch to quick and snappy.

Has anyone else noticed this?

Thanks, Ryan.

Hi Ryan, I'm also experiencing slow switching between DocumentContent tabs.
I was wondering if you've found anything to improve the performance?

I'm using DataGridControls as the tab content. Grids with more data take longer to switch to.
I've found that collapsing the grid visibility improves GUI responsiveness. I was thinking if the visibility could be collpased when the tab isn't in focus, and only after the tab has received focus to set grid visibility back. This may give the impression that the GUI is more responsive?

What are your thoughts?
