Asked On July 21, 2016 09:33 PM UTC

Hello, I have server side changes/alerts that I want to notify/show the user, for e.g. Message is -> request approved.

  • Since the user is in the same page/view in ASP MVC 4.52, how can my server publish-push this message to any view in the client session to his front end browser.
  • please share a working sample (with the latest js, and SyncF libs) on how can we show this to user in his view, and let it fade after 5 seconds.
  • Or user can dismiss by clicking on it
  • Which control is best suited, I was assuming dialog, is this correct?




thanks
Mega

Hi Megatron,    
   
Thanks for your update.   
   
We can able to build and run the shared sample. We request you to configure “Microsoft ASP.NET SignalR” nugget package in your machine. If you have configured correctly, then the sample will build and works fine.   
    
For more information, please refer the below links to getting started with SignalR nuget package.

Please find the modified project for hosting purpose from the below link: http://www.syncfusion.com/downloads/support/forum/125107/ze/SignalRChat-1384283074

Hi, I suggest you first google this -  CS0619    'SignalRRouteExtensions.MapHubs(RouteCollection)' is obsolete: 'Use IAppBuilder.MapSignalR in an Owin Startup class. - it shows you're using unsupported code in your samples

If you look at your sample - it clearly shows signarlR version 1. Microsoft has deprecated this, and no longer supporting it, its SignarlR V2.

Your sample contains outdated code and libs from MVC 2, so it runs on your machine, trying updating the nuget packages - all Microsoft will show you the link to the code that has been deprecated.

Hi Megatron, 
 
Thanks for your update. 
 
We have provided you with a simple sample using SignalR concept with our Dialog control to achieve your requested scenario. As you have mentioned the previously updated sample uses SignalR 1.1 and MVC 4 version. If you have configured for SignalR 2.2.1 (current stable verion) from nugets, then please follow the steps in the below link because of deprecated MapHubs. 
 
We have upgraded the sample with SignalR 2.2.1 and its available in the following link: 
 
If this isn’t your requirement, please share us a simple sample based on your application scenario about the server side changes that are intended to be notified in client side and update us with further details it. Also explain the difficulties you are facing with Syncfusion Dialog in your case. So that we can help you out better to use our controls.

Hi, even with this version the code seems to have been copied and pasted from over 3 yrs ago, its not working, can you give me a working version with current libs working for vs 2015

I mentioned 3 days ago, "Your sample contains outdated code and libs from MVC 2,"  that its using the old MVC libs, and I asked for the current versions.

it still using the old not supported code - compiler in 4.5.2 and 4.6.1 are both complaining -> SignalRRouteExtensions.MapHubs(RouteCollection)' is obsolete

Severity    Code    Description    Project    File    Line    Suppression State
Error    CS0619    'SignalRRouteExtensions.MapHubs(RouteCollection)' is obsolete: 'Use IAppBuilder.MapSignalR in an Owin Startup class.  for more details.'    SignalRChat    C:\users\megan\SignalRChat-21725252725\SignalRChat\Global.asax.cs    19    Active

I looked at the dependencies and upgraded to the correct jquery version.
