Hi Elio,

Good day to you.

We have checked the reported issue at our end. In Server side Blazor projects, if we are using a large amount of data to render items as in this sample or in general, we need to add below configuration in the startup.cs file to avoid the below exception.

Exception

fail: Microsoft.AspNetCore.SignalR.HubConnectionHandler[2]

Error when processing requests.

System.IO.InvalidDataException: The maximum message size of 32768B was exceeded.

The message size can be configured in AddHubOptions.

Configuration

services.AddServerSideBlazor().AddHubOptions(o =>

{

o.MaximumReceiveMessageSize = 102400000;

});

We have modified your sample.

Sample

Kindly check the above sample and get back to us if you need any further assistance.

Regards,

Kanagambigai M.
