          SelectionMode="None"
          HasUnevenRows="True"
          x:Name="DeviceListView">
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell>
                <ViewCell.View>
                    <Grid Margin="14">
                        <Grid.ColumnDefinitions>

                            <ColumnDefinition Width="auto"/>
                        </Grid.ColumnDefinitions>
                        <Label Grid.Column="0"
                               FontFamily="MaterialFont"
