This is not a bug, and is working as intended.  The annotation data that you save has no representation of the WebAnnotationViewer's current zoom level. If you are saving the annotation data inside a tiff file, it's possible for you to save the Zoom level of the WebAnnotationViewer in a Tiff Tag, and set that zoom level when reloading that ...

If you set that property during the loading process, the javascript value can get stomped on by the server value.  You can set the InteractMode on the server side (in the aspx file), or make sure that the control has finished loading before you set that value.  If this user doesn't have rights to modify any ...

Actually, if you just want the page number or file name, the ThumbCaptionFormat property of the WebThumbnailViewer supports this.  From the documentation: ThumbCaptionFormat Property The text to use as the caption for each thumbnail.  It is passed to String.Format, and {0} will be replaced by the page number of the thumbnail, and {1} ...

Clicking through transparent areas of Referenced or EmbeddedImageAnnotations are not supported. I am not sure what you mean by the AllowClickThrough property.  The only property that I can think of that resembles that (on the ASP.NET side) is the MouseTool PassThrough option, which allows all mouse events to pass through to the underlying ...

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 ...

I can see how this would be a problem.  The alert() function interrupts the flow of mouse events and changes focus.  If you do this during a mousedown + mousemove + mouseup series of events, you will need to call OnMouseUp (in this case) to reset the events back to a normal state when focus is lost.

I have tested this demo using our latest 8.0 release, and I cannot reproduce the problem. Have you modified the demo at all? What browser are you using?

That is exactly what I thought you wanted to do.  The WebAnnotationViewer is capable of keeping track of multiple layers of annotations, but not multiple images.  If you have linked the two controls together, the WebThumbnailViewer assumes that each layer in the WebAnnotationViewer represents a page of annotations. So, you will have to ...
