ContentView doesn't show ContentControl

[Andreas Sprengard]

Hi,

i got a short question about theSfNavigationDrawer.ContentView. I use Prism and want to add to the ContentView to a Prism Region. Does the ContentView doesn't support ContentControls?

My code snippet:

        <Grid Grid.Row="1">

            <Grid.ColumnDefinitions>

                <ColumnDefinition/>

                <ColumnDefinition/>

            </Grid.ColumnDefinitions>

            <sf:SfNavigationDrawer x:Name="drawer"

                IsOpen="True"

                DrawerWidth="300"

                Position="Left"

                TouchThreshold="35"

                Transition="Push">

                <sf:SfNavigationDrawer.DrawerHeaderView>

                    <Grid Background="{DynamicResource HeaderBackgroundColor}"

                        Height="120">

                        <Border BorderBrush="{DynamicResource BorderColor}" BorderThickness="1,0,1,1" />

                        <Image Source="/Sample.Desktop;component/Resources/icon.png" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="Fill" Width="100" Height="100" />

                    </Grid>

                </sf:SfNavigationDrawer.DrawerHeaderView>

                <sf:SfNavigationDrawer.DrawerContentView>

                    <Grid>

                        <Border BorderBrush="{DynamicResource BorderColor}" BorderThickness="1,0,1,1" />

                        <ListBox Padding="0,8,0,0" 

                            Background="White"

                            ItemsSource="{Binding Menu}"

                            ItemContainerStyle="{StaticResource listboxitemStyle}" Margin="5">

                            <ListBox.ItemTemplate>

                                <DataTemplate>

                                    <sf:NavigationItem Command="{Binding DataContext.NavigationCommand, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" 

                                        CommandParameter="{Binding}"

                                        IconMemberPath="{Binding IconSource}"

                                        Header="{Binding Header}" />

                                </DataTemplate>

                            </ListBox.ItemTemplate>

                        </ListBox>

                    </Grid>

                </sf:SfNavigationDrawer.DrawerContentView>

                <sf:SfNavigationDrawer.ContentView>

                    <ContentControl Grid.Column="1" prism:RegionManager.RegionName="ContentRegion" />

                </sf:SfNavigationDrawer.ContentView>

            </sf:SfNavigationDrawer>

            

            <ContentControl Grid.Column="1" prism:RegionManager.RegionName="ContentRegion" />

        </Grid>

Best regards

Hi Sakthivel,

i found out that the Parent object is null and the region needs to be registered.

MainWindow.xaml.cs:

        public MainWindow(IRegionManager regionManager)

        {

            InitializeComponent();

            var parent = LogicalTreeHelper.GetParent(this.contentRegionControl);

            if (regionManager != null)

            {

                SetRegionManager(regionManager, this.contentRegionControl, "ContentRegion");

            }

        }

        void SetRegionManager(IRegionManager regionManager, DependencyObject regionTarget, string regionName)

        {

            RegionManager.SetRegionName(regionTarget, regionName);

            RegionManager.SetRegionManager(regionTarget, regionManager);

        }

Attached a sample app.

Best regards

Andreas
