The QuickGrid component in Blazor takes an IQueryable object which is defered so the execution of the query is done inside the QuickGrid

How can I display a loading indicator while the Quickgrid does its magic?

@using Microsoft.AspNetCore.Components.QuickGrid
<QuickGrid  Items="results" />

private IQueryable results{ get;set;}
protected override void OnInitialized()
{
     results = ActivityService.GetActivities();
}

thanks
