I've been using RadDataBoundListBox to develop an app with a forum. Everything worked extremely well until I added images into the item template.
An item in the list (i.e. a post in the forum) is composed of a text block with string content as well as an image control. The image is downloaded from the remote server, of which the height can be up to 1500 pixels. After the whole list had been loaded successfully, it behaved abnormally when scrolling. When the item with a long image was realized, the list suddenly jumped several items back or front. Moreover, I made my way to the top of the list and found the pull-to-refresh indicator disappeared, but it was still functioning.
I thought that this problem has something to do with the virtualization technique. Setting the RealizedItemsBufferScale property to a larger value doesn't seem to help at all. Could you please give me a solution? Many thanks.
