Verbesserung der Lesbarkeit von Tabellenkalkulationsdaten

November 28, 2025
Mit Formatierungs- und Präsentationsfunktionen können Sie Informationen einfach präsentieren, um den Nutzern die Navigation komplexer Arbeitsblätter mit geringerem Aufwand zu erleichtern.

Formatting and presentation features shape how information is communicated within a spreadsheet, turning raw values into content that is clearer, more readable, and visually consistent. These capabilities help users emphasize key data, establish a coherent visual style, and create worksheets that are easier to interpret at a glance. By supporting both subtle adjustments and more expressive enhancements, they play a central role in making spreadsheets suitable for reporting, analysis, and presentation-focused tasks across a wide range of scenarios.

Common features include:

  • Barcodes convert cell values into machine-readable symbols that can be used for tracking, inventory, or integration with external systems.
  • Cell Formatting controls the appearance of content through adjustments to fonts, colors, borders, alignment, and number formats.
  • Charts present data visually through a variety of graphical formats, making patterns and comparisons easier to understand.
  • Conditional Formatting applies visual cues dynamically, helping users identify trends, exceptions, or threshold-based results without manual intervention.
  • Inserting Images enables users to place graphics directly into worksheets, supporting richer presentations and adding contextual detail where needed.
  • Themes provide a foundation for consistent styling by applying coordinated colors, fonts, and effects across an entire spreadsheet.

Feinabstimmung der Werteingabe mit Schiebereglern

November 27, 2025
Bietet Nutzern einen intuitiven Trackbar-Dateneditor, der die numerische Eingabe verbessert, gültige Bereiche beibehält und visuelles Feedback liefert.

A trackbar in data editors provides a sliding control that allows users to adjust numeric values within a defined range through an interactive visual interface. It reduces the need for manual text entry, prevents invalid inputs by enforcing minimums, maximums and step increments, and offers immediate feedback as values change. Trackbars are especially useful in scenarios where users need to fine tune settings such as selecting volume levels, adjusting brightness, setting filter thresholds or choosing time or price ranges, making them ideal for applications that benefit from quick, intuitive and precise value selection.

Several .NET WinForms components offer Trackbar Data Editors including:

Hinzufügen handschriftlicher Notizen zu PDFs in Web-Apps

November 26, 2025
ASP.NET Core-PDF-Steuerungen mit freihändigem Zeichnen und Tintenanmerkungen ermöglichen es Nutzern, Signaturen, Skizzen und Notizen direkt zu Dokumenten hinzuzufügen.

Freehand Draw, also known as Ink Annotation, in ASP.NET Core PDF Viewer controls allows users to add freeform, hand-drawn annotations directly onto PDF documents. This feature mimics natural handwriting or sketching by enabling input through mouse, touch, or stylus, making it especially useful for scenarios requiring personal notes, signatures, or diagrammatic feedback. The annotations are embedded as part of the PDF, ensuring they remain accessible and visible across different platforms and viewers. It is commonly used in applications where document review or digital signing is required, enhancing interactivity and collaboration within PDF-based processes.

Several ASP.NET Core Assembly PDF Viewer components offer support for Freehand Draw/Ink Annotation including:

  • Document Solutions for PDF by MESCIUS allows you to draw free‑hand ink annotations that capture user‑stroke paths and embed them as editable vector markup within a PDF.
  • ImageGear .NET by Accusoft enables freehand and polyline annotation so developers can capture scribbles, arrows or curves and save them as PDF annotation objects.
  • Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) supports ink annotation within its viewer, enabling users to draw and add signatures to PDFs.
