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.

• CSHTML
• JavaScript

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

<script type="text/javascript" id="script">
    function customizeMenuAction(s, e) {
        // Get the "Export" action and hide it.
        var exportAction = e.GetById(DevExpress.Reporting.Viewer.ActionId.ExportTo);
        if (exportAction)
            exportAction.visible = false;
