Calculated field from another field

[yangetze]

Hi community, I have a question.

I have two numeric fields (field1, field2).
field2 is calculated as from field1. I need to show that result in the input everytime there's a change in field1.

<NumericEdit TValue="decimal" Value="@NewInput.Field1" ValueChanged="@OnField1Changed"></NumericEdit>

<NumericEdit TValue="decimal" @bind-Value="@NewInput.Field2" ReadOnly="true"</NumericEdit>

In the class I have this

 public void OnField1Changed(decimal valField1) {
            NewInput.Field2 =
                SomeAppService.Caculate(valField1, 100M)
                .Result;
        }

But I did't see any result.
I have something wrong? I test the method OnField1Changed on my backeand and it works.
Is there another way to solve this?

Blazorise version: 0.9.3-preview6

Thx in Advanced!

Try this:

<NumericEdit TValue="decimal" Value="@Field1" ValueChanged="@OnField1Changed" />

<NumericEdit TValue="decimal" Value="@Field2" ReadOnly="true" />

@code{
    decimal Field1;

    decimal Field2;

    Task OnField1Changed( decimal newValue )
    {
        Field1 = newValue;

        Field2 = Field1 * 0.25m;

        return Task.CompletedTask;
    }
}

I think you only missed Task on the method OnField1Changed. It must be available so that Blazor can update the tree.

Also, you don't need @bind- for the readonly field.
