We just bought the controls and realized that there is no support to bind a collection of images to the ThumbnailViewer. We have tried to create an attached dependency property in which to add manually the images to the thumbnail viewer but with no success. Any suggestions? Our whole application is 100% based on MVVM.
Sorry for the late reply. Since my last post we have resolved this issue by subclassing the WPFThumbnailViewer control and adding a normal dependency property and it works now, thank you very much.
