Alex,

I recognize this is an older post but I want to follow-up and see if anyone has come up with a solution for the ever growing collection of uncollected Infragistics objects in your application. I am experiencing similar growth. I've attached an image of the profilier which clearly shows the object growth. This is not small potatoes stuff, and after a handful of clicks on my master/detail style grid and tabs, I'm already in the 600+ range. I've long ago dealt with the proportions of my data and their instances. If I remove any addtional data, my application will be blank, ugh.

Thanks,

Glenn Long

Hello,
Can you provide us with a sample that we can profile? 

I am seeing a similar problem, and am not using UnboundFields.  As I'm scrolling down the rows memory usage increases to about 1GB, then the application will either freeze for a few minutes and memory usage goes back down to 100MB, or the application throws an out of memory exception.

I am not completely sure (perhaps someone from the development team can correct me) but I think that this might be preventing the virtualization of the cells horizontally - and that is why you see increased memory usage and the InitializeCellValuePresenter is not firing.

Hi Alex,

Yes, I'm using UnboundFields with custom templates. Does that has impact? I haven't isolated this yet, the grid has very heavy reliance on the underlying datasource.

Thanks.
