DevExpress WinForms is a comprehensive suite of 190+ UI controls and development tools designed for building high-performance desktop applications.

Improve Pie Chart Clarity with Side-Aligned Labels

December 29, 2025
ComponentOne Studio WinForms 2025 v2 enhances FlexPie with side aligned labels for cleaner visuals and improved readability.

ComponentOne Studio WinForms by MESCIUS is a comprehensive toolkit offering over 120 advanced UI components to improve Windows Forms application development. It helps you to build visually appealing and feature-rich applications with functionalities like data visualization through charts and reports, intuitive data editing with performant grids, and modern UI elements including ribbons and docking for a user-friendly experience.

The ComponentOne Studio WinForms 2025 v2 update introduces a new data label placement option for FlexPie that aligns labels along the left and right sides of the chart to improve readability and visual structure. By moving labels out of the pie area, this option reduces overlap and congestion when working with datasets that contain many slices or small values, which are common challenges in pie chart rendering. The result is a more consistent and predictable layout that helps developers present data more clearly while maintaining a clean, modern appearance across different screen sizes and data scenarios.

This capability delivers a clear visual understanding of gradients, surface characteristics, and other continuous data patterns. With support for multiple contour types, customizable contour levels, and flexible gradient color palettes, developers gain precise control over how value transitions are presented.

Optimize Report Inputs with Purpose-Built Dialogs

December 11, 2025
Create cleaner, more consistent reports with dialog parameter forms, ensuring accurate, validated inputs for filters, groupings, and calculations.

Dialog forms for parameters in reporting provide a structured and user friendly way to collect the inputs needed for accurate, relevant reports. Instead of relying on manual entry or remembered criteria, users are guided through fields that ensure consistent and valid information. This improves report quality and reduces errors in scenarios such as choosing date ranges, product categories, regions, or departments. By centralizing parameter entry in a clean interface, dialog forms let users focus on interpreting results rather than managing input details.

Several .NET WinForms reporting components allow you to create dialog forms for parameters, including:

  • DevExpress Reporting lets you create guided parameter dialogs that collect accurate user inputs, improving report precision, usability, and efficiency across applications.
  • Telerik Reporting allows you to build intuitive parameter dialogs that improve data selection, ensuring users generate consistent, reliable reports with minimal effort.
  • FastReport .NET WinForms facilitates customizable parameter dialogs that validate user input, enhancing report accuracy and simplifying complex filtering and configuration tasks.
  • Stimulsoft Reports.NET enables structured parameter dialog creation that helps users supply correct reporting criteria, delivering clearer insights and more dependable results.
