Handle the ValueChanged event to track when the value of a Ribbon Spin Editor or Combo Box changes.

The following code snippet monitors the value of the Spin Editor component:

<DxRibbon>
    <DxRibbonTab Text="Home">
        <DxRibbonGroup>
            <DxRibbonSpinEditItem Value="@NumberOfRows"
                                  ValueChanged="@((int newValue) => OnValueChanged(newValue))"
                                  MinValue="1"
                                  MaxValue="8" />
        </DxRibbonGroup>
    </DxRibbonTab>
</DxRibbon>

<p>Number of Rows: <b>@CalculatedValue</b></p>

@code {
    private int NumberOfRows { get; set; } = 2;
    private string CalculatedValue = "Even";

    private void OnValueChanged(int value)
    {
        NumberOfRows = value;
        CalculatedValue = value % 2 == 0 ? "Even" : "Odd";
    }
}
