Azure SignalR Service (serverless) best practice to initially populate grid

[Muttley]

So in 2019 Telerik support told me Serverless is not supported. Well it's 2021 and I can't be the only person using the Azure SignalR Service "serverless".

I know it's not officially supported by Telerik as server SignalR methods can't be invoked with Serverless but I have got changes showing in the grid from a Razor page. The issue is I can't get the grid initially populated as I just see a spinner until the first update is received from the SignalR Service.

I'm thinking of initialising the grid datasource as SignalR, then I could perform an Ajax call to get the initial data, then leave it to receive updates from that point. Anyone in the community using grids with SignalR in this way? I'd appreciate any experiences whilst Telerik play catch up.

Many thanks.

Hi,

There haven't been changes implemented to specifically target the serverless Azure SignalR Service. I am no Azure expert, but I found out that there is currently a preview feature that allows you to invoke a hub method from clients in serverless mode:

Azure Serverless Upstream settings

Is it possible that this feature will allow you to invoke the desired method?

I also came across this blogpost which I understand solves a similar scenario to what you would like to achieve.
