Breaking change on ValueChanged since v3.3.0 release? (NumericTextBox)

[Ecofip]

Hello, 

Here is the issue we encoure since version 3.3.0 of Telerik for Blazor.
Everything worked fine in version 3.2.0. We have a simple Input model, and a classic form.
The behavior that we want is "when Value1 changes, Value2 must change with custom logic". 

Here is our code: 

<p>Value1 : @Person.Value1</p>
<p>Value2 : @Person.Value2</p>

<TelerikForm Model="@Person">
    <FormValidation>
        <DataAnnotationsValidator></DataAnnotationsValidator>
    </FormValidation>
    <FormItems>
        <FormItem Field="@(nameof(Person.Value1))">
            <Template>
                <label class="k-label k-form-label">Value 1</label>
                <div class="k-form-field-wrap">

                    <TelerikNumericTextBox Decimals="2"
                                           Format="C"
                                           Min="0"
                                           Step="0.01m"
                                           ValueChanged="@((decimal? v) => Value1ChangedHandler(v))"
                                           Value="@Person.Value1"
                                           ValueExpression="@(() => Person.Value1)">
                    </TelerikNumericTextBox>
                    <TelerikValidationMessage For="@(() => Person.Value1)"></TelerikValidationMessage>
                </div>
            </Template>
        </FormItem>

        <FormItem Field="@(nameof(Person.Value2))">
        </FormItem>
    </FormItems>
</TelerikForm>

public partial class Example
{
    private Input Person { get; set; } = new();

    protected override void OnInitialized()
    {
        Person = new()
        {
            Value1 = 1000,
            Value2 = 2000,
        };

        base.OnInitialized();
    }

    private void Value1ChangedHandler(decimal? newValue1)
    {
        this.Person.Value1 = newValue1;
        this.Person.Value2 = newValue1 * 2; // We tried to add StateHasChanged(), but not working as well
    }
}

public class Input
{
    public decimal? Value1 { get; set; } 
    public decimal? Value2 { get; set; }
}

I attach two GIF recordings, the first is version 3.2.0 (working as expected), the second is version 3.3.0, you will see that the behavior is very odd.

Thanks a lot in advance.

Hello Emmanuel,

I used the provided code snippet to test the behavior in both a local server-side project using 3.4.0(our latest release), as well as older versions. I also tested it in REPL. In all my tests the component behaved as expected(as shown in V3.2.0.gif). I am wondering if it could be something due to the update, like a cache issue for example - clearing it might help.

I am also attaching a gif of the observed behavior.

In the meantime, could you please have a look here: https://blazorrepl.telerik.com/GmaVEFOJ51bfIkBu29, and let me know if this works for you? The REPL is running our latest version (3.4.0). Thanks!

Hello @Radko,

Thanks a lot for your answer, and you were right, it was a cache issue. We fell sorry for that but maybe it could help someone in future!

Thanks again,
