让范围输入更简单

5月 12, 2026
范围栏数据编辑器允许用户交互式定义最小和最大允许值，从而减少了在报表、仪表盘和表单中的手动录入。

A Range Trackbar in ASP.NET Core Data Editor controls is an interactive input component that lets users select a numeric range by moving two handles along a track, rather than typing minimum and maximum values into separate fields. This makes range-based data entry faster, clearer, and less error-prone, especially when the valid values are bounded, such as prices, dates, percentages, ratings, quantities, or performance thresholds. For developers, it provides a more intuitive way to capture structured range input while maintaining control over validation, step intervals, formatting, and default values. In real-world applications, a Range Trackbar can be used in product filters to select a price range, reporting dashboards to define a date or score interval, booking systems to choose acceptable time windows, analytics tools to adjust threshold limits, or administrative forms where users need to configure minimum and maximum values without manually entering exact numbers.

Many ASP.NET Core Assembly Data Editors collections contain Range Trackbar controls including:

  • DevExpress ASP.NET Core Data Editors (part of DevExpress ASP.NET & Blazor) let you add Range Trackbar inputs for selecting numeric intervals clearly within responsive data forms.
  • Telerik UI for ASP.NET Core Data Editors (part of Telerik UI for ASP.NET Core) allows you to present Range Trackbar selection for filters, thresholds, and configurable values.
  • Wisej.NET enables Range Trackbar-style range selection in ASP.NET Core applications, supporting selection within minimum and maximum values for business data entry.
  • Syncfusion ASP.NET Core Data Editors (part of Syncfusion Essential Studio Enterprise) facilitates Range Trackbar input for choosing minimum and maximum values.

用清晰的横向和纵向图表展示业务指标，有助于用户识别模式和性能变化。

Column and bar charts are among the most widely used data visualization features in modern charting components, helping developers present comparisons, trends, and category-based metrics in a format that is easy to interpret. By displaying values as horizontal or vertical bars, these chart types allow applications to communicate changes in performance, rankings, distributions, and other business data with clarity. Modern charting components typically support customization options such as stacked series, grouped categories, animations, tooltips, responsive layouts, and interactive behaviors, enabling developers to create dashboards and reporting experiences that suit a wide range of enterprise and analytical scenarios.

Several Blazor chart controls offer column and bar charts including:

  • DevExpress Blazor Charts (part of DevExpress ASP.NET and Blazor) provides column and bar chart types with support for stacked and full-stacked series and crosshair cursors.
  • Telerik UI Blazor Chart (part of Telerik UI for Blazor) includes configurable bar and column series with data binding, responsive rendering,and interactive features.
  • Syncfusion Blazor Charts (part of Syncfusion Essential Studio Enterprise) offers a broad collection of bar and column chart variations including stacked and range.
  • Infragistics Ignite UI for Blazor Chart (part of Infragistics Ignite UI) delivers high-performance column and bar chart visualizations with advanced data interaction.

在具备 CSV 导出功能的 Blazor 应用程序中，从报表数据生成 CSV 文件，从而简化跨平台数据交换。

Exporting reports to CSV (Comma-Separated Values) format provides a simple and widely compatible way to transfer report data into spreadsheet applications, databases, analytics platforms, and other business systems. CSV files store structured data as plain text, making them easy to process, automate, archive, and exchange across different environments. For software developers and business users, CSV export functionality supports data analysis, operational reporting, integration workflows, and data retention requirements while maintaining low file complexity and broad platform support.

Several Blazor reporting components allow you to export to CSV, including:

  • DevExpress Reporting provides Blazor-compatible CSV export functionality, allowing users to generate structured data files with configurable export options.
  • ActiveReports .NET Professional (part of ActiveReports .NET by MESCIUS) offers CSV rendering and export features for reports in Blazor applications.
  • Telerik Reporting supports CSV export through its Blazor report viewers and rendering extensions, with configurable settings for output formatting and data structure.
  • Stimulsoft Reports.WEB supports CSV export in web and Blazor reporting apps, allowing report data to be used in spreadsheets, integrations, and downstream processing.

DevExpress Blazor 包括内置筛选器构建器对话框，让用户无需编写其它代码即可创建复杂的网格和 TreeList 筛选器。

DevExpress Blazor (part of DevExpress ASP.NET and Blazor) helps you create high-impact user experiences for both Blazor Server and Blazor WebAssembly using C#. The Blazor UI Component Library ships with a comprehensive set of native components including a Grid, Pivot Table, Scheduler, Chart, Data Editors and Reporting.

DevExpress Blazor now includes an integrated Filter Builder for its Grid and TreeList components, making it easier for users to define advanced filtering criteria through a visual interface. Filter Builder fields are generated automatically from existing data columns, so developers can add sophisticated filtering capabilities without extra configuration or custom implementation work. This approach helps users work with large datasets more efficiently while maintaining a consistent experience across Blazor applications.
