Inform user of long processes

Radzen Studio Blazor Server

Hi, i want to inform the user when he clicked on a button that the process takes a long time.

My code:

protected async Task HeatPumpGridInterpolatedButtonClick( MouseEventArgs args, PiCon.Models.DbPiCon.HeatPump heatPump )
{
if ( await DialogService.Confirm( "This operation takes some time!" ) == true )
{
DialogService.Close();
isLoading = true;

			// what to do to show the spinning icon
			// what to do if the dialog is visible that the dialog closed
			// the user has to be informed on the running process it takes about 2-4 minutes

			var selectedValues = await DbPiConService.GetHeatPumpValues(
				..... );

			var selectedInterpolated = await DbPiConService.GetHeatPumpInterpolateds(
				...... );

			var result = Calculators.UpdateInterpolated( selectedValues, selectedInterpolated );
			await DbPiConService.UpsertHeatPumpInterpolatedBulk( result.ToList() );

			NotificationService.Notify( new NotificationMessage
			{
				Severity = NotificationSeverity.Success,
				Summary = $"Succes",
				Detail = String.Format( "{0} records interpolated", result.Count() )
			} );
		}
		isLoading = false;
	}

Hi @RacketRebel,
Have you tried the progress bar component?

Hoi Not yet, but there is an property / field 'isLoading' that should work if it's set to true.
I think the UI is also not updated when the button actions are still in progress, even they are async Tasks, But i will try it.
