ASPxWebDocumentViewer.StaticInitialize() Method

Explicitly starts the Web Document Viewer initialization.

Namespace: DevExpress.XtraReports.Web

Assembly: DevExpress.XtraReports.v21.1.Web.WebForms.dll


public static void StaticInitialize()


The ASPxWebDocumentViewer is automatically initialized when rendering on your application’s Web page, but in specific cases, you need to trigger its initialization explicitly (for instance, when an AppPool is recycled).

The StaticInitialize method does the following:

  • Calls the static ASPxWebDocumentViewer constructor;
  • Registers HttpHandlers required for the Web Document Viewer;
  • Initializes all services for processing requests to the corresponding handler.

Use the StaticInitialize method at the application startup in the Global.asax file.


To make the Document Viewer’s handlers work correctly, you should call this method after specifying the session state and registering additional services.

protected void Application_Start(Object sender, EventArgs e) {
    // ...  
   DevExpress.XtraReports.Web.WebDocumentViewer.Native.WebDocumentViewerBootstrapper.SessionState = 
    // ...
