It seems, that using RadDataBoundListBox with wrap virtualization strategy for image loading from rest services, causes momory leak as listbox ItemsSource gets larger. From what can i assume, when wrap virtualization strategy is applied, something goes wrong with template recycling and virtualization.
You can download test example here: http://failiem.lv/u/szohumv
This example is directly taken from Telerik team examples project.

Hi Janis,

Thanks for writing.

Can you please open a new support ticket and attach your project there as we cannot download it from the website you provided?

Thanks for your time.

Hi, Janis/ Deyan,

Has there been any outcome to this?

I am having very similar issues which seemed to be addressed in a few forum posts but as of yet there are no definitive answers.

I have replicated the Telerik example for RadDataBoundListBox for the OnDemand scenario. However, with the wrap virtualization and trying to  have a control which can shows 100's+ images, I always reach an OutOfMemoryException.

My items source is that of an ObservableCollection, as used in the example.
My item template is simply an Image with its source binding to the uri string of a given image (the thumbnail in this case).
I have a DataVirtualizationItemTemplate with a simple 'get more' functionality, similar to what is shown in the Telerik example once more.

Is there any reason why I would be getting this?

Many Thanks,

Mike
