Blazor Binding Live Data
La Ignite UI for Blazor puede gestionar miles de actualizaciones por segundo, a la vez que mantiene la cuadrícula activa ante cualquier interacción que pueda llevar a cabo el usuario. Puede utilizar el siguiente ejemplo para comprobar el rendimiento del procesamiento de la cuadrícula en varios escenarios de datos en vivo ajustando el intervalo entre las actualizaciones de datos, así como el volumen de las actualizaciones de datos.
