The AllowDragDrop property in the WebThumbnailViewer allows individual thumbnails to be dragged and dropped within the bounds of the same WebThumbnailViewer. Dragging thumbnails outside to another WebThumbnailViewer is not currently supported, and is currently on our feature list for a future release.

A log file in the AtalaCache (AtalasoftWebControls_Cache in Web.config) will tell you what caused the error. If you are opening a folder of thumbnails without using wildcards such as *.tiff,  and a text file or some other non-image file exists in the folder, it will show this error. At this time, there is no way to hide the error ...

I know this question is a bit older, but I thought I would still post an answer in case someone else had the same problem. There is an event called ''onthumbnaildrop'' that can be used on the server side to reorder the file.  It is located in the Events property grid in the designer.  You can also use the source view to manually add the ...

Hi, I have a web application which I want to provide image viewing for. I've read your documentation about loading images into the thumbnail viewer and can't see a way to load them the way I wish to. So I'm writing this to see if you have any ideas? My scenario is that we have documents, which are made of 1 to many files and each file has 1 ...

In a regular .Net application outside of sharepoint thumbnail images and the main image in the WebAnnotationViewer load fine.  In sharepoint 2007:- thumbnail images do not load. - WebAnnotationViewer partially loads the image, but has a broken image on the right hand side of the viewer- The application is in a folder under the layouts ...

Some files cause this error. The files are .tiffs and are Group 4 Fax Encoding. They open OK in various image viewing programs. Is there a workaround? Thanks, Brian

Hi, I'm using a solution like the one described here ( http://www.atalasoft.com/cs/forums/post/15556.aspx ) to show/hide a button on a page depending on the format of the Image selected. The problem is that the WebAnnotationViewer doesn't show the selected image if the RemoteInvoke gets called on the SelectedIndexChanged handler. Here's ...

The best way to do this is to use a working copy of a multipage tiff image, and instead of rotating the image directly with the WebImageViewer's ApplyCommand, use a RemoteInvoke that rotates the current image, and stuffs the changes back into the working image.  Once the RemoteInvoke comes back to the client side, you can then force the ...

I found a solution. I had a multipage document, but it was stored as single pages. So I created a directory for displaying them all with the WebThumbnailViewer. Now I changed my code that I first create one single multipage TIFF from all the single TIFF pages. With this change it works.

When I create an annotation on one page of a multipage TIFF and go to another page via the WebThumbnailViewer I see the annotation on every page with the WebAnnotationViewer. But I want it only on one page not on every page.  How can I do that?
