In case of a big document tiff file that has around 200 pages the thumbnail viewer generates 200 thumbnails.
The client wishes to implement a paging system that will only show 15 page thumbnails at a time.
Is there a way to tell Thumbnail viewer control to show thumbnails between a range?
Just turn the PreloadAllItems property to False to automatically render asynchronously visible items. In case you want to add each item one by one just have a look on the reference guide in the ThumbnailEx section. You will find everything needed to handle the behavior of the control.
I ended up manually adding thumbnail by AddItemFromGdPictureImage() method
Thanks for your prompt reply
