Enterprise-level component library based on Bootstrap and BlazorAuto Refresh table
In a certain application scenario, the change of the data source needs to refresh the table component
Auto Refresh
This example demonstrates monitoring the data source in a background thread, and notifies the table component to refresh the data when the data source changes
Demo
The auto refresh function is enabled by setting the value of the IsAutoRefresh property. The default value of the AutoRefreshInterval property is 2000 milliseconds, which is the auto refresh interval, and the component's QueryAsync is called periodically. The method makes the table auto-refresh
In this example, a new piece of data is added every 2 seconds and a maximum of 10 pieces of data are maintained
