Hi,
I Blazor WASM .net 6 visual studio 2022
I am trying to pass a negative parameter between pages but it doesn't work - it always pass an extra string '%E2%80%8E' at the beginning
for example if I pass -33333
http://localhost:8082/Counter/%E2%80%8E-33333
if I pass positive number then if works
Now the weird thing is that in debug IT DOES WORK :) - http://localhost:8082/Counter/-33333
but when I publish it to IIS then it disrupts the parameter and add the '%E2%80%8E'
this is just an example but In my real app I do pass negative parameter and it breaks it - it used to work on .net core 3.1.
I am adding screen shots to show you the problem +
the code which is basically nothing - I modified the 2 files from razor suffix to txt so they can be uploaded
Thanks
Arik
this is the index.razor code:
@Anonymous "/"
@inject NavigationManager urlNavigationManager
@inject IJSRuntime JSRuntime
<PageTitle>Test Failure passing negative parameters</PageTitle>
<input id="bnt" type="button" @onclick="ButtonClick" value="Move To"/>
<EditForm Model="@this">
<div>
<span>somenumber:</span>
<InputNumber @bind-Value="SomeNumber" />
</div>
</EditForm>
@Aidan Wick
{
public long SomeNumber { get; set; } = 99999;
public async void ButtonClick()
{
//fails
urlNavigationManager.NavigateTo($"/Counter/{SomeNumber}");
//failures samples
//http://localhost:8082/Counter/%E2%80%8E-33333
//failes
// urlNavigationManager.NavigateTo($"/Counter/{SomeId}/true/{SomeNumber}/dummy");
// urlNavigationManager.NavigateTo($"/Counter/{GetSomeid()}");
}
}
this is the counter.razor code:
@Anonymous "/counter/{somenumber:long}"
<PageTitle>Counter</PageTitle>
<h1>Counter</h1>
<div>@somenumber</div>
[Parameter]
public long somenumber { get; set; }
protected override async void OnInitialized()
{
// await JSRuntime.InvokeVoidAsync("alert", $"someid:{someid},somenumber:{somenumber},shouldrequesttosyncdevice:{shouldrequesttosyncdevice}");
}
}
The %E2%80%8E is the left to right mark. My best guess is the left to right mark came from a copy and paste??? Or perhaps a bug with how the URLs are generated.
if you will have a look at the code above -
at index.razor :
urlNavigationManager.NavigateTo($"/Counter/{SomeNumber}");
where SomeNumber is just a long variable - it's dyncamic, no copy paste problem
it works in debug!
it fails after publish to IIS - only after I upgraded to .net 6 - it used to work on .net core 3.1.
very weird

Try to use the following code, and check whether it works well on IIS:
urlNavigationManager.NavigateTo("/Counter/-33333");
Besides, whether you are using IIS URL rewrite or not?
Thank you I have already done this test and IT DOES work this way -> urlNavigationManager.NavigateTo("/Counter/-33333");
so weird :)
difference here is the the parameter is long - see 'SomeNumber ' variable
public long SomeNumber { get; set; } = 99999;
public async void ButtonClick()
{
//fails
urlNavigationManager.NavigateTo($"/Counter/{SomeNumber}");
...
Another option that didn't work is this (converting the long to string):
public async void ButtonClick()
{
//fails
urlNavigationManager.NavigateTo($"/Counter/{SomeNumber.ToString()}");
That's crazy, by the way it also fails on API calls if I try make a call
say I would make that call it will fail (simple API which also works in debug):
var x = await Http.GetFromJsonAsync<WeatherForecast>($"WeatherForecast/GetById/{SomeNumber}");
Again, E2 80 8E is the left-to-right control character. Blazor runs in the browser so try a different browser. Also, disable any browser plugins.
No URL rewrite - simple publish to IIS
OK thank you! excellent -
on IIS
If you are still having trouble with Chrome then it's probably settings. See Chrome support for configuring text direction or reset chrome to default. Anyway, Chrome support is a better place to get help.
Yeh I will Thanks buddy :)
I now tried to run it on a different machine with chrome and it work
Refining the scenario Thanks to AgaveJoe

Here's the solution for anyone coming across this post in the future like me. You need to "clean" the int value so it's culture specific before passing it to the NaviateTo function.
int x = -123456789;
var cleaned = x.ToString(CultureInfo.CreateSpecificCulture("en-us"));
NavigationManager.NavigateTo("counter/" + cleaned);
