Remarks

Handle the ValueChanged event to respond to the value change. The following code snippet enables the Update Value button once a user changes the editor value.

<DxSpinEdit Value="@NumericValue" ValueChanged="@((int newValue) => OnValueChanged(newValue))"></DxSpinEdit>
<DxButton Enabled="@IsEnabled">Update Value</DxButton>

@code {
    int NumericValue = 0;
    bool IsEnabled = true;

    void OnValueChanged(int newValue) {
        NumericValue = newValue;
        if (newValue != 0)
            IsEnabled = false;
        else IsEnabled = true;
    }
}

You can also use the DevExpress.Blazor.DxSpinEdit`1.ValueChanging event to validate/cancel user input.
