On an ASP.NET page with WebThumbnailviewer and WebAnnotationViewer, I load a one-page document. When I create an annotation , it does not update the thumbnailviewer. I load a 4 page document and create an annotation on first page it does not appear in the thumbnailviewer. I navigate to next page and create an annotation and it updates the ...

The main problem with percentage based height, especially in IE, is that every single parent element all the way up to the root html node must have a defined height in order for this to work.  This includes the html, body, form, and any master page placeholder tags between the form and the object you want to size with ...

Good morning, David. I have some additional questions that go along with this topic, which I hope you'll be able to answer. You mentioned issues with loading WANG annotations at different points in the WebAnnotationViewer's life cycle.  With that in mind: 1.  Do these issues occur with XMP annotations, too, or just WANG?2.  We ...

The only time the server side SelectedIndex or SelectedIndexes properties will be changed is on a PostBack.  If you are attempting to access these properties from a RemoteInvoke, please keep in mind that a RemoteInvoke only maintains state on the control from which it was called from.  Every other control on the page (in a RemoteInvoke) ...

My objective is to write a browser based application to do the following: Load one or more multi-page TIFF images from a directory Allow viewing, reordering, and rotating of pages Split or group ranges of pages into their own multi-page TIFF (or insert separator page to designate start of a new section/document) Preferably use a TreeView to ...

I am working with the WebThumbnailViewer and WebAnnotationViewer and would like to make the annotations made in the viewer show up in the thumbnail.  In the DotImageWebForms demo shipped with 5.0 that does not happen, but in the AJAX Document and Annotations Editor demo on the AtalaSoft website, it does happen.  The methods ...

Actually, there is a way... whe WebThumbnailViewer.UrlChanged JavaScript event is fired after the asynchronous callback has completed.  This is probably what you want to use.

That specific error message looks like the PDF decoder is not initialized when the asynchronous requests for the thumbnails are requested.  To fix this issue, you can add the PDF Decoder to the RegisteredDecoders on the Page Init event. I have a suggestion that may improve your performance for this situation (Once you get the PDF loading): ...
