                    <Style TargetType="GridViewItem">
                        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>

                </GridView.ItemContainerStyle>
                <GridView.ItemTemplate>
                    <DataTemplate x:DataType="model:Bank">
                        <Grid HorizontalAlignment="Stretch">

                                <RowDefinition Height="auto" />
                                <RowDefinition Height="auto" />
                            </Grid.RowDefinitions>
                            <TextBlock Text="{Binding Name}" Grid.Column="0" />

                            <GridView ItemsSource="{x:Bind Departments}" Grid.Row="1" HorizontalContentAlignment="Stretch" IsItemClickEnabled="True" VerticalContentAlignment="Stretch">
                                <GridView.ItemContainerStyle>
                                    <Style TargetType="GridViewItem">
                                        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
                                    </Style>
                                </GridView.ItemContainerStyle>
                                <GridView.ItemTemplate>
                                    <DataTemplate x:DataType="model:Department">
                                        <Grid HorizontalAlignment="Stretch">
                                            <Grid.ColumnDefinitions>
                                                <ColumnDefinition Width="250" />
                                                <ColumnDefinition Width="*" />
                                                <ColumnDefinition Width="40" />
                                            </Grid.ColumnDefinitions>
