Steigern der Leistung von Blazor Rastern mit virtuellem Bildlauf

Dezember 19, 2023
Sie können mühelos große Datasets laden und darstellen, indem Sie nur Zeilen darstellen, die im aktuell sichtbaren Bereich angezeigt werden.

For large datasets, traditional grid scrolling struggles to maintain performance, often becoming sluggish and resource-intensive. Virtual scrolling provides a more efficient alternative. Instead of rendering the entire dataset at once, it dynamically fetches and displays only the visible rows, keeping the rest cached and unloaded. This significantly reduces the number of elements in the application, resulting in a noticeably smoother scrolling experience, even with millions of data points. Virtual scrolling empowers users to seamlessly explore expansive datasets without compromising performance or responsiveness.

Several Blazor grid components support virtual scrolling including:

  • DevExpress Blazor Data Grid (part of DevExpress ASP.NET and Blazor) is a high-performance, feature-rich grid with seamless virtual scrolling for large datasets.
  • FlexGrid for Blazor (part of ComponentOne Studio Blazor by MESCIUS) is a flexible and customizable grid with efficient virtual scrolling for data-intensive applications.
  • Infragistics Blazor Data Grid (part of Infragistics Ignite UI) is a comprehensive grid solution with advanced virtual scrolling capabilities for enterprise-level applications.
  • Syncfusion Blazor DataGrid (part of Syncfusion Essential Studio Enterprise) is a versatile grid with optimized virtual scrolling for handling massive datasets seamlessly.
  • Telerik UI for Blazor Grid (part of Telerik UI for Blazor) is a powerful grid component which uses smooth virtual scrolling to navigate large data sets efficiently.

Wenden Sie visuelle Hinweise auf bestimmte Zellen, Zeilen oder Spalten basierend auf ihren Datenwerten an, um das Erkennen von Mustern und Trends zu erleichtern.

Conditional formatting in grids allows users to apply visual styles to cells or ranges based on the data they contain. It enhances data readability and analysis by highlighting critical values, outliers, or trends in a data-driven manner. For instance, a cell might be colored red if it contains a value below a certain threshold, thereby drawing attention to potential issues.

Several WinForms grid components support conditional formatting including:

  • DevExpress WinForms Data Grid (part of DevExpress WinForms) enhances data visualization with rich conditional formatting rules including custom visual styles.
  • FlexGrid for WinForms (part of ComponentOne Studio WinForms by MESCIUS) enables conditional cell styles, visual indicators and data-driven formatting.
  • Infragistics WinDataGrid (part of Infragistics Ultimate UI for Windows Forms) includes sophisticated formatting rules, conditional cell backgrounds, and data-driven visual cues.
  • NOV Grid for .NET (part of Nevron Open Vision for .NET) provides custom formatting expressions, data-driven cell styles and conditional background colors.
  • Telerik UI for WinForms GridView offers rule-based cell formatting, visual indicators, and data-driven formatting logic.
