   Implements INamingContainer, ICallbackEventHandler, IPostBackDataHandler, INotifyPropertyChanged

public: 
   [ToolboxDataAttribute(L"<{0}:WebThumbnailViewer runat=server Width=220px Height=320px BorderWidth=1px Bor"  
   L"derStyle=Solid></{0}:WebThumbnailViewer>"),  
   DefaultPropertyAttribute(L"ViewerID")] 
   ref class WebThumbnailViewer : WebControl, INamingContainer, ICallbackEventHandler,  
    IPostBackDataHandler, INotifyPropertyChanged

Remarks

The WebThumbnailViewer can display the pages of a multipage image in an auto-scrollable view.

To use this control properly, LEADTOOLS binaries must be installed on the server machine.

Only the viewed thumbnails images are loaded (load OnDemand).

This Control works only with ASP.NET 2.0.

Be sure that the DLLs in the LEADTOOLS I/O Library are available to your application. There are two ways of doing this:

Install the DLLs in the application's directory

Install them in the Global Assembly Cache (GAC). For more information on this method, refer to The Microsoft Gacutil Tool.
