Spread.NET Versionen

Spread Windows Forms and Spread WPF:

• New Pivot Table Style Options - Take greater control over how your PivotTables look and feel. With new style options, you can now customize header appearances and apply banded row and column formatting. The result is cleaner, more readable PivotTables that make complex data easier to interpret at a glance.
• Group Dialog for Pivot Fields - Grouping data is now more intuitive than ever. In addition to existing API-based grouping for numbers and dates, V19.1 introduces a designer-based dialog that supports grouping for numbers, dates, and now text. This enhancement simplifies data organization directly within your workflow.
• Active Cell Focus Highlighting - Navigating large datasets just got easier. With the new FocusCellMode property, you can highlight the active cell's row, column, or both - making it simple for users to track their position and reduce errors during data entry or analysis.
• Support for .NET 10 and Visual Studio 2026 - Stay up to date with the latest development platforms. Spread for Windows Forms and Spread WPF v19.1 fully supports .NET 10 and Visual Studio 2026, ensuring compatibility with modern development environments and future-ready applications.

Spread Windows Forms:

• New PivotTable Protection Option - Enable secure interaction with PivotTables even on protected worksheets. The new 'Use PivotTable' option allows users to work with PivotTables without removing sheet protection. Configure it easily through the Designer or programmatically via the AllowUsingPivotTables property.
• Paste Data Beyond Sheet Boundaries - Handling large data imports is now more flexible. The new PastingExceededValues option lets you control how pasted data behaves when it exceeds worksheet limits. Combined with the new ClipboardPastingEventArgs event, you gain fine-grained control over row and column expansion during paste operations.
• Seamless Hierarchical Scrolling Transition - Working with hierarchical (parent-child) data views is smoother than ever. Spread Windows Forms now supports seamless scrolling transitions between child and parent views, improving navigation and delivering a more natural user experience.

Spread WPF:

• Drag Fill Support - Boost productivity with built-in drag fill functionality. Users can quickly populate cells by dragging across rows or columns - mirroring the familiar auto-fill experience found in spreadsheets like Excel.
• Data Visualization Functions - Bring your data to life directly within cells. Spread WPF now supports data visualization functions, enabling you to create custom-rendered visuals such as sparklines and other graphical indicators. These functions combine calculation logic with rendering capabilities, opening the door to highly interactive and insightful spreadsheet designs.
