Example

<dxe:ButtonEdit ButtonsSource="{Binding Items}">
    <dxe:ButtonEdit.ButtonTemplate>
        <DataTemplate>
            <ContentControl>
                <dxe:ButtonInfo Command="{Binding Command}"
                                Content="{Binding Content}"
                                IsLeft="{Binding IsLeft}"/>
            </ContentControl>
        </DataTemplate>
    </dxe:ButtonEdit.ButtonTemplate>
</dxe:ButtonEdit>
