And I am implementing it like this using Syncfusion's ProgressBar but other controls pretty much use the same parameters:

In my AdjustmentsController I have the following (I've removed some code for brevity):
namespace MyApp.Web.Controllers
{
public class AdjustmentsController : MyAppControllerBase
{
private readonly ISignalRCommon _progressBar;
private readonly IAppFolders _appFolders;
public AdjustmentsController(
ISignalRCommon progressBar,
IAppFolders appFolders)
{
_progressBar = progressBar;
_appFolders = appFolders;
}
[HttpPost]
public virtual async Task> ProcessBulkAdjustments()
{
var files = Request.Form.Files;
var notes = Request.Form["notes"];
var errors = new List();
if (notes.IsNullOrEmpty())
{
errors.Add("Missing notes.");
return errors;
}
if (files == null)
{
errors.Add("No files found to process.");
return errors;
}
foreach (var file in files.Where(q => q != null && q.Length > 0))
{
var error = await BulkAdjustments(file, notes);
if (!error.IsNullOrWhiteSpace()) errors.Add($"{file.FileName}\r\n{error}");
}
return errors;
}
public async Task BulkAdjustments(IFormFile file, string notes)
{
var fileName = Path.GetFileName(file.FileName);
if (fileName.IsNullOrWhiteSpace()) return L("File_Empty_Error");
//New instance of ExcelEngine is created
//Equivalent to launching Microsoft Excel with no workbooks open

var worksheet = workbook.Worksheets.FirstOrDefault();
if (worksheet == null) return "No worksheet found";
var start = worksheet.UsedRange.Row;
var end = worksheet.UsedRange.LastRow;
var col = worksheet.UsedRange.Column;
var bulkUpdates = new List<SomeDataDto>();
for (var row = start + 1; row <= end; row++)
{

};
bulkUpdates.Add(someDataDto);
await _progressBar.SendProgress(L("ParsedRow"), row, end, someDataDto);
}
var count = 0;
var totalCount = bulkUpdates.Count;
var errors = string.Empty;
foreach (var bulkUpdate in bulkUpdates)

// errors = await doSomething();
}
await CurrentUnitOfWork.SaveChangesAsync();
}
await _progressBar.SendProgress(L("ProcessingComplete"), count, totalCount);
return errors;
}
}
}
In MyApp.Core/Common, I have ISignalRCommon.cs:
namespace MyApp.Common
{
public interface ISignalRCommon
{
Task SendProgress(string message, int progressCount, int totalCount, object data = null);
}
}
In MyApp.Web.Core/Common/SignalR, I have CommonHub.cs and SignalRCommon.cs:
namespace MyApp.Web.Common.SignalR
{
public class CommonHub : Hub
{
}
}
namespace MyApp.Web.Common.SignalR
{
public class SignalRCommon : ISignalRCommon, ITransientDependency
{
private readonly IHubContext _commonHub;
public SignalRCommon(IHubContext commonHub)
{
_commonHub = commonHub;
}
public async Task SendProgress(string message, int progressCount, int totalCount, object data = null)
{
var progress = new ProgressDto
{
Message = message,
ProgressCount = progressCount,
PercentComplete = (progressCount * 100) / totalCount,
TotalCount = totalCount,
Data = Newtonsoft.Json.JsonConvert.SerializeObject(data)
};
await _commonHub.Clients.All.SendAsync("sendProgress", progress);
return progress;
}
}
}
Finally, ProgressDto:
namespace MyApp.Common.Dto
{
public class ProgressDto
{
public string Message { get; set; } = string.Empty;
public decimal ProgressCount { get; set; } = 0;
public decimal PercentComplete { get; set; } = 0;
public decimal TotalCount { get; set; } = 0;
public string Data { get; set; } = string.Empty;
}
}
Hi @dzungle, sorry for the very late reply.
I've broken it down into what I hope will make sense and hope that I haven't forgotten anything.
In app.component.ts and app.module.ts, I import the service:
import { CommonSignalrService } from '@app/shared/common/signalR/common-signalr.service';
In app.component.ts add to constructor:
private _commonSignalrService: CommonSignalrService,
and init with the chat signalr service:
if (this.appSession.application) {
SignalRHelper.initSignalR(() => {
this._chatSignalrService.init();
this._commonSignalrService.init();
});
}
The common-signalr.service.ts:
import { Injectable, Injector, NgZone } from '@angular/core';
import { AppComponentBase } from '@shared/common/app-component-base';
import { HubConnection } from '@microsoft/signalr';
@Injectable()export class CommonSignalrService extends AppComponentBase {
constructor(
injector: Injector,
public _zone: NgZone
) { super(injector);
}
commonHub: HubConnection;
isCommonConnected = false;
configureConnection(connection): void { // Set the common hub
this.commonHub = connection;
// Reconnect loop
let reconnectTime = 5000;
let tries = 1;
let maxTries = 8;
function start() { return new Promise(function (resolve, reject) {
if (tries > maxTries) {
reject();
} else { connection.start()
.then(resolve)
.then(() => {
reconnectTime = 5000;
tries = 1;
}) .catch(() => {
setTimeout(() => {
start().then(resolve);
}, reconnectTime);
reconnectTime *= 2;
tries += 1;
});
} });
}
// Reconnect if hub disconnects
connection.onclose(e => { this.isCommonConnected = false;
if (e) { abp.log.debug('Common signalR connection closed with error: ' + e);
} else { abp.log.debug('Common signalR disconnected');
}
start().then(() => {
this.isCommonConnected = true;
});
});
// Register to get notifications
this.registerCommonEvents(connection);
}
registerCommonEvents(connection): void {
connection.on('sendProgress', (progress) => {
abp.event.trigger('app.progress.received', progress);
});
}
init(): void {
this._zone.runOutsideAngular(() => {
abp.signalr.connect();
abp.signalr.startConnection(abp.appPath + 'signalr-common', connection => { this.configureConnection(connection);
}).then(() => { abp.event.trigger('app.common.connected');
this.isCommonConnected = true;
});
});
}}
My ProgressBarDto:
import { Inject, Injectable } from '@angular/core';
@Injectable()export class ProgressBarDto implements IProgressBarDto {
message = '';
progressCount = 0;
percentComplete = 0;
totalCount = 0;
data: any;
constructor(@Inject(ProgressBarDto) data?: IProgressBarDto) { if (data) {
for (let property in data) {
if (data.hasOwnProperty(property)) {
(<any>this)[property] = (<any>data)[property];
} }
this.data = JSON.parse(data['data']);
} }
static fromJS(data: any): ProgressBarDto {
data = typeof data === 'object' ? data : {};
let result = new ProgressBarDto();
result.init(data);
return result;
}
init(data?: any) {
if (data) {
this.message = data['message'];
this.progressCount = data['progressCount'];
this.percentComplete = data['percentComplete'];
this.totalCount = data['totalCount'];
this.data = JSON.parse(data['data']);
} }
toJSON(data?: any) {
data = typeof data === 'object' ? data : {};
data['message'] = this.message;
data['progressCount'] = this.progressCount;
data['percentComplete'] = this.percentComplete;
data['totalCount'] = this.totalCount;
data['data'] = JSON.stringify(this.data);
return data;
}}
export interface IProgressBarDto {
message: string;
progressCount: number;
percentComplete: number;
totalCount: number;
data: any;
}
Hi @musa.demir, @ismcagdas,
I found the issue - it was a typo in the event name in the controller - "abp." instead of "app.".
Wg
Hi @musa.demir, @ismcagdas,
I have initialized my signalr service along with the chat service:
if (this.appSession.application) {
SignalRHelper.initSignalR(() => {
this._chatSignalrService.init();
this._commonSignalrService.init();
});
}
In my service, this is working and I am receiving the messages from the server:
registerCommonEvents(connection): void {
connection.on('sendProgress', (progress) => {
console.log('sendProgress', progress);
abp.event.trigger('app.progress.received', progress);
});
}
However, in my component, this is not working:
ngOnInit(): void {
super.ngOnInit();
abp.event.on('abp.progress.received', (progress) => {
console.log('progressReceived', progress);
this.progress = progress;
});
}
Any thoughts?
Thanks,
Wg
Hi @ismcagdas,
Is there any code I can look at to do this?
Thanks,
Wg
Hi @billyteng,
Thanks very much! It worked for me too.

Thanks @ismcagdas; the project was generated using the generate latest drop down in the download history section.
A new project was generated manually using the .NET 5 selection and it ran successfully this time without any issues; I assume that it did not update the framework when generating from tthe download history.
I look forward to 10.1 to fix the change prefix issue (or perhaps a specific fix that I can implement sooner).
Thanks,
Wg
Hi @ismcagdas,
I will create an issue on GitHub.
I downloaded the project today @ 10:15am MST. The error I receive for all the projects is:
NU1202 Package Abp.AspNetZeroCore 3.0.0 is not compatible with netcoreapp3.1 (.NETCoreApp,Version=v3.1). Package Abp.AspNetZeroCore 3.0.0 supports: net50 (.NETFramework,Version=v5.0) PTA.Web.Host

Hi @maliming,
Yes, thanks,
