A subreport in a report component is a report embedded within another report, designed to present related or supplementary data that may not fit naturally into the main report’s structure. It is typically used when displaying hierarchical, grouped, or master-detail relationships, such as showing order items within a customer order summary. Subreports can be independently designed and then linked to the main report using parameters or shared data sources. This modular approach improves report organization and reusability, especially when similar data blocks are needed across multiple reports or sections within a complex reporting solution.
Several Angular Reporting controls offer support for subreports including:

Telerik Report Server is a comprehensive and flexible end-to-end solution for managing reports. Built with the Telerik Reporting library, it is a server-based Windows web application that provides centralized storage, organization, and previewing of reports, along with features for scheduling, delivery, and user management. Report Server can act as a standalone solution or be integrated within an application, allowing developers to create, manage, and distribute reports across multiple platforms including Blazor, Angular and Windows Forms.
The Telerik Report Server 2025 Q3 update introduces white-labeling, allowing development teams to align the Report Server web application and Standalone Report Designer with their organization’s visual standards. This capability enables administrators to replace default branding elements such as colors, logos, and favicons with enterprise-specific assets, creating a consistent user interface across internal systems. By integrating into existing environments, the update helps reduce visual fragmentation, improve user trust, and improve the experience for both internal and external stakeholders.

Telerik Report Server is available individually or as part of Telerik DevCraft Ultimate.

Ellipse annotations in PDF viewer components are shape‑based markups that allow users to draw oval or circular outlines (or filled ellipses) on PDF pages. Such annotations are valuable in highlighting regions, drawing attention to content, or visually marking up documents for review without altering the underlying text. They generally include settings for border color, line width, fill color or transparency, and may offer popup notes, captions, or comments associated with the ellipse shape. The feature supports both interactive use and programmatic control in many viewers.
Several React PDF viewer controls offer support for ellipse annotations including:

TeeChart Pro VCL/FMX by Steema Software is a comprehensive charting library designed for Embarcadero's Delphi and C++Builder environments, supporting both the VCL (Visual Component Library) and FMX (FireMonkey) frameworks. It provides developers with a rich set of chart types, advanced data visualization tools, and interactive features to build visually compelling and data-intensive applications across Windows, macOS, iOS, and Android. With support for real-time charting, custom drawing, statistical functions, and export capabilities, TeeChart Pro is tailored for high-performance applications that demand precise and dynamic chart displays.
The TeeChart Pro VCL/FMX 2025 (Build 2025.45.250910) update introduces the Sankey Series chart type, which gives developers a new tool for visualizing flows and relationships in data (e.g. movement of quantities between states, split‑paths, or aggregations). It enables rendering of nodes and links whose thickness is proportional to the magnitude of the flow, allowing you to more directly see how values distribute and split across paths. This enhances insight into complex datasets in ways that standard bar, line, or pie charts cannot, helping in diagnosing bottlenecks, tracing resource paths, or modelling multi‑stage processes with clarity.

TeeChart Pro VCL/FMX is licensed per developer and includes a one year subscription for minor and major updates plus access to technical support. Priority support is also available. See our TeeChart Pro VCL/FMX licensing page for full details.
