Document Viewer's Client-Side Events

The Web Document Viewer control provides an advanced client-side API in addition to the comprehensive server-side object model. This enables web applications based on this control to function more efficiently by combining server-side and client-side processing.

The WebDocumentViewerClientSideEventsBuilder class exposes methods that allow you to pass client-side events' handlers. To access this class instance, use the WebDocumentViewerBuilder.ClientSideEvents method.

@{
    var documentViewer = Html.DevExpress().WebDocumentViewer("webDocumentViewer1")
        .Height("1000px")
        .Bind(Model.Report)
        .ClientSideEvents(configure => { configure.CustomizeMenuActions("customizeMenuActions"); });;
