I'm working through this example, although slightly changed a bit, but I am getting a http 400.
I am trying to upload a json file.  The api path looks right when I debug but the request never makes it to the controller, however, I dont think its a routing issue as I would get a 404 error instead?

Is this only for Client-side Blazor?

Ok, figured out what I was missing.  I thinkg I ran into this when I was building a Razorpages app.

It was a routing issue after all.  Got to enable routing to api and other controllers, in Startup
This isnt enabled by default in a new Blazor server-side app (not sure about Client side)

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
                endpoints.MapBlazorHub();
                endpoints.MapFallbackToPage("/_Host");
            });

Oh, and its likely you will need to add this in Startup for ConfigureServices, if you havent already
            // web api
            services.AddControllers().AddNewtonsoftJson();

Hello Randal,

In our Create Project Wizard the endpoints.MapControllers(); should be enabled by default, you could try and create a new project and if it still missing you can open a Support ticket so we can further investigate.

On the NewtonsoftJson framework, it is up to the application to define what third-party software products it will use.

Hitting the same problem.

Can you include an Upload page in the Telerik Blazor Server template, then we can see how it works?

Hello Peter,

You can see how to setup the Upload component from our documentation, link here: https://docs.telerik.com/blazor-ui/components/upload/overview. In general, creating the Controller for the upload does not differ from the one you have for your database.

You can also check our demos project that you have in the "demos" folder of your installation for an example.

As attached file you can see a demo project which has the Upload set up.
