Is there an example of reordering thumbnails using ItemDrag and ThumbnailDrop for the Thumbnailviewer?  We have DotImage 5.0.2868.18055. 

Hi,  I'm developing an application that scan images and search for barcodes. The images are shown in a thumbnailview, i need to highlight the images with barcodes changing the backcolor. Is it possible?  Thanks in advance          

I am using the folderThumbnailView control in my app and I also have the Atalasoft PDFRasterizer - my question is: how can I make the thumbnailviewer show PDF images - I have added the .pdf extension to the filter property but still no joy. Please help. Thankyou.

Depending on how you've coded your application, the FilePath property in the Thumbnail class could have the filename.  However if the thumbnail was added manually, this is likely to be null, in which case you can add the filename to the read/write Tag property and keep track if it that way.
