EdgeDragablz

A Mash Up of HandyControl and Dragablz

Usage

1. Add reference to NuGet packages HandyControl and Dragablz (in this project I've used this port to .NET Core)

2. Copy ResourceDictionary file TabablzControl.xaml to your project

3. Add the following to App.xaml

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/SkinDefault.xaml"/>
            <ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/Theme.xaml"/>
            <ResourceDictionary Source="Themes/Styles/TabablzControl.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

Databinding

4. Add the following to MainWindow.xaml

    <dragablz:TabablzControl ItemsSource="{Binding Documents}" 
                             SelectedItem="{Binding Document}" 
                             Style="{StaticResource HandyTabablzStyle}" 
                             ShowDefaultCloseButton="True" >
        <dragablz:TabablzControl.HeaderItemTemplate>
            <DataTemplate DataType="{x:Type local:Document}">
                <TextBlock Text="{Binding Header}" />
            </DataTemplate>
        </dragablz:TabablzControl.HeaderItemTemplate>
        <dragablz:TabablzControl.ContentTemplate>
            <DataTemplate DataType="{x:Type local:Document}">
                <Border Background="{Binding Background}" />
            </DataTemplate>
        </dragablz:TabablzControl.ContentTemplate>
    </dragablz:TabablzControl>

Prism

Usage with Prism is fairly more complex. Please refer to sample code to correctly implement App.xaml.cs, MainWindowViewModel and RegionAdapter.

4. Add the following to MainWindow.xaml

<dragablz:TabablzControl x:Name="Tabs" prism:RegionManager.RegionName="{x:Static local:RegionHelper.RegionName}"
                            Style="{StaticResource TabablzEdgeStyle}" ShowDefaultCloseButton="True">
        
    <dragablz:TabablzControl.InterTabController>
        <dragablz:InterTabController InterTabClient="{Binding InterTabClient}"/>
    </dragablz:TabablzControl.InterTabController>
        
    <dragablz:TabablzControl.HeaderItemTemplate>
        <DataTemplate DataType="{x:Type vm:DocumentViewModel}">
            <Grid>
                <Grid.ContextMenu>
                    <ContextMenu>
                        <!--we'll be in a popup, so give dragablz a hint as to what tab header content needs closing -->
                        <MenuItem Command="{x:Static dragablz:TabablzControl.CloseItemCommand}"/>
                        <MenuItem Command="{x:Static dragablz:TabablzControl.CloseOtherItemsCommand}"/>
                    </ContextMenu>
                </Grid.ContextMenu>
                <TextBlock Text="{Binding DataContext.Header}" MaxWidth="100" TextTrimming="CharacterEllipsis" ToolTip="{Binding DataContext.Header}" />
            </Grid>
        </DataTemplate>
    </dragablz:TabablzControl.HeaderItemTemplate>
                
</dragablz:TabablzControl>

Issues

De-registration of region is not happening correctly when tab is teared-off

Next developments

1. Complete DragablzItemsControl style using UniformGrid
2. Inclusion of TabablzControl in NonClientAreaContent (possible?)
