The Grid is supposed to show a loading animation when it detects a data operation that requires more than 600ms to complete. However, if this operation is triggered programmatically through the state and not through the UI, the loading indicator is not shown.

A possible workaround for the time being is to use a LoaderContainer component when invoking programmatic data operation similar to how the initial loader is shown here: https://demos.telerik.com/blazor-ui/grid/loading-animation.
