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!

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.
