I will try to see if I can isolate this issue.

One thing I noticed is that if I don't specify editor style in the field, it will reclaim memory when scrolling.

However, strange enough, if I don't specify that, the

OnInitializeCellValuePresenter

doesn't get hit when I'm scrolling horizontally, but I'm relying on that event to do formatting.

Thanks. 

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.

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.

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.

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

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
