Hi all,

I am trying to navigate to another page in onclick event after a http service call, but i am unable to navigate, instead it is loading the same page with "?" appended at the end.

My onclick event is as follows

protected async Task checkpnr()
        string uri = baseurl + "api/pnr/" + pnr + "/check";     
       string isvalidpnr = await Http.GetStringAsync(uri);
        if (isvalidpnr == "true")
            await JsRuntime.InvokeAsync<bool>("setpnr", pnr);
            showerror = true;

in the output I am getting

Navigated to http://localhost:50506/?

[Violation] 'setTimeout' handler took 178ms      mono.js

In the above code if i remove service call and assign a static value to isvalidpnr, I am able to navigate to the mentioned page.

please let me know what the issue is and how to solve it.

Did you bound your function to a button in form ?
If so, try change button type
from <button type="submit" ...
to <button type="button" ...

Hope that helps.

yes it helped.. thanks a lot.. but the behavior is strange,with type="submit" it sometimes works correctly and the other time it doesn't.

Oh I see - you were submitting the form. Since you don't want to do that, be sure to use type=button.

Also please note that we no longer accept issues posted to this repo. Instead, issues relating to Blazor or Razor Components should be posted at
