Aumente o desempenho do Blazor Grid com a rolagem virtual

Dezembro 19, 2023
Carregue e renderize conjuntos grandes de dados sem esforço renderizando apenas as linhas que aparecem na área visível no momento.

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.
