<Button Content="Close">
    <dxmvvm:Interaction.Behaviors>
        <dxmvvm:ConfirmationBehavior EnableConfirmationMessage="{Binding IsSaved, Converter={StaticResource BooleanNegationConverter}}" 
                                     Command="{Binding CloseCommand}" MessageText="The document has unsaved changes. Do you want to close the document?"/>
    </dxmvvm:Interaction.Behaviors>
</Button>
