Show partial thumbnails for a very large document

Post by pankaj5k » Mon Mar 25, 2013 2:42 pm

Hi Guys,

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?

Or how can i manually add thumbnails for each page in the thumbnail viewer using javascript/vbscript? In this case i will handle the paging logic myself.

Please help

Hellp,

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.

Kind regards,

Loïc

Hi Loic,

I ended up manually adding thumbnail by AddItemFromGdPictureImage() method

Thanks for your prompt reply
