@ITninja04 , I have a feeling it is the Thread.Sleep
inside of async code. Try Task.Delay
and see if you get the same issue.
from blazor-state.
I noticed that small state changes that happen while an action is being handled do not always trigger 'StateHasChanged'.
StateHasChanged is triggered via middleware after and action is handled. It won't matter if it is a small change or big.
I handle Loading with ProcessingBehavior
Middleware as follows. This gives us both Global and Action specific loading indicators. Ping me on Discord for more details.
public class ProcessingBehavior<TRequest, TResponse> : IPipelineBehavior<TRequest, TResponse>
{
private readonly IMediator Mediator;
public ProcessingBehavior(IMediator aMediator) { Mediator = aMediator; }
public async Task<TResponse> Handle
(
TRequest aRequest,
CancellationToken aCancellationToken,
RequestHandlerDelegate<TResponse> aNextHandler
)
{
if (typeof(TRequest).GetCustomAttributes(typeof(TrackProcessingAttribute), false).FirstOrDefault() != null)
{
Guard.Support(aRequest is IAction);
Guard.Argument(aRequest as object, nameof(aRequest))
.NotType<StartWaitingAction>()
.NotType<StopWaitingAction>();
string actionName = typeof(TRequest).Name;
await Mediator.Send(new StartWaitingAction { ActionName = actionName }).ConfigureAwait(false);
TResponse response = await aNextHandler().ConfigureAwait(false);
await Mediator.Send(new StopWaitingAction { ActionName = actionName }).ConfigureAwait(false);
return response;
}
else
{
TResponse response = await aNextHandler().ConfigureAwait(false);
return response;
}
}
}
