Slow updates with propertygrid...

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have several property grids that need to be updated whenever a file is opened - sometimes with 20K lines total, in up to 3 or 4 levels - and my performance is bad (7600 line update, four grids, 44 seconds).  I tried calling BeginUpdate/EndUpdate and the time went down to 43 seconds.  Not exactly the increase i was hoping for.

I am out of ideas  -  anybody have any?  

Thanks!

- David

	Hi, its too much lines. Only to create 10000 CXTPPropertyGridItem objects will take 7-9 seconds. for (int i = 0; i < 10000; i++) { new CXTPPropertyGridItem(1, ""); } Think you need to change logic of your application. Make some filter. Don't think somebody ineed need 10000 lines in propertygrid.
