    In This Topic

    With Web Viewers, you can view reports in Blazor, ASP.NET Core, ASP.NET MVC, Angular, React, HTML5/JS applications. These viewers are lightweight with built-in support for client-side printing. Like Desktop Viewers, the Web Viewers are feature-rich that allow you to easily view, print, and export reports. The viewers are highly interactive, giving you the ability to enter parameters, perform sort and drill down, navigate to other reports using drill-through links, and so on. The multiple View Modes let you display your reports as Paginated, Continuous, or in Galley view. In addition, the viewers are customizable and localizable according to the personal needs.

    The viewer API lets you customize the viewers and blend them into your web page. The features or buttons can be added or hidden on viewers toolbar and sidebar, the parameters panel can be customized, and so on. For this, you must have hands-on experience in coding; visit these set of article if this is the case.

    As Report Readers, let us focus on the UI of Web Viewers.
