ASP.NET CoreのグリッドデータをPDFにエクスポートし、簡単に共有してオフライン分析や記録管理可能

PDF export is a powerful feature in grid controls, allowing users to capture and share data presented in a readily accessible format. This functionality typically involves dedicated methods or settings within the grid, enabling seamless transformation of the displayed data into a structured PDF document. Users often have control over what sections and columns to export, along with formatting options like headers, fonts, and page layout. This flexibility makes PDF export ideal for generating printable reports, archiving snapshots of grid data, and distributing information beyond the confines of the application.

仮想スクロールによるBlazorグリッドのパフォーマンスの向上

現在表示可能な領域に表示されている行のみをレンダリングすることで、大規模なデータセットを簡単に読み込んでレンダリング可能

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.

データ値に基づいて特定のセル、行、または列に視覚的な手がかりを適用し、パターンや傾向を簡単に識別できるようにします。

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.
