Add children of children user control to parent - c#

I want to implement toolbox like control in WPF using User controls. I'm able to get the all Titles of UCITems and shown as tabs in UCTab and binded to StackPanel in UCTab using ContentProperty. But I need UCItem childrens also and bind to another stack panel in UCTab.
MainWindow.xaml:
<local:UCTab>
<local:UCItem Title="ToolBox 1">
<StackPanel>
<TextBlock Text="1"></TextBlock>
<TextBlock Text="2"></TextBlock>
<TextBlock Text="3"></TextBlock>
</StackPanel>
</local:UCItem>
<local:UCItem Title="ToolBox 2"></local:UCItem>
<local:UCItem Title="ToolBox 3"></local:UCItem>
</local:UCTab>`

On click of UCItem button, display UCItem content Stackpanel 'panelUCItem' in UCTab.
Help me how I can proceed with this structure. Thanks

How can I make controls in WPF stretch to fill available width when HorizontalAlignment and HorizontalContentAlignment don't work?

I'm trying to make a simple WPF app that has sections that fill the available width. Despite trying various ways of stretching the width of elements, containers, and children, nothing is working and I can't figure out why.
Another question said to use uniformgrid which worked well EXCEPT that it set the height of all the elements uniformly which was definitely not what I wanted. I want all of the sections to look like the one in the picture - filled width, height auto based on the content. Here's the basic setup:
<Window x:Class="A_Customizer.MainWindow"

StackPanel with Orientation="Vertical" (default value) instead of WrapPanel should work: it will allow each child element use full width and as much height as necessary

WPF a scrollviewer in an itemscontrol in a groupbox not showing all items

I've an usercontrol with a groupbox where there's an itemscontrol in it.
Within the itemscontrol I put an scrollviewer.
When I run the application it isn't showing all the items.
Sometimes I see 1 or 2 items, sometimes nothing.
I'am certain that my list has at least 10 items in it.
What am I doing wrong here?
I've put the scrollviewer in the itemscontrol like described here:

The items are loaded in with a viewmodel and is called from within the constructor of the viewmodel:
private void GetHistory()
{
HistoryBLL historyBLL = new HistoryBLL();
HistoryDataTable myHistory = historyBLL.GetHistoryByDeviceId(Device.Id);
foreach (HistoryRow row in myHistory)
{
UnitsBLL unitsBLL = new UnitsBLL();
Items.Add(new HistoryListItemViewModel
{
Date_cal = (DateTime)row.date_cal,
Device_name = row.tagnaam,
Unit_name = unitsBLL.GetUnitById(row.unit_id).unit,
Sensor = row.sensor_id.ToString(),
Battery = (row.battery) ? "Ja" : "",
Comments = row.comments
});
unitsBLL = null;
}
}
When I put a breakpoint at the last line I can see that the List of Items is filling up with at least 10 items, so that part is working.
I expect to see all the items and not just 1 or 2 (of even nothing)

Text not wrapping in ListViewItem

The ListViewItems are getting their width from the TextBlock element. I want the ListViewItem to fit to the ListView. I have seen in other posts that making HorizontalContentAlignment="Stretch" will fix the issue, but my problem persists. The second TextBlock element in the ItemTemplate is set to WrapWithOverflow.

Right width of wpf expander header

I've found an solution of my problem.
Width=”{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=x:Type Expander}}, Path=ActualWidth}”
But I've got not correct width. (the width of the toggle button is not taken into consideration)
Is there any solutions in XAML for this?

How do you allow multiple children in a UserControl?

I have the following user control:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Label Grid.Row="0" Content="USER CONTROL" HorizontalAlignment="Stretch" HorizontalContentAlignment="Center" Name="label1"
VerticalAlignment="Top" FontSize="26" Padding="0"/>
<ScrollViewer Grid.Row="1" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled">
<Border BorderBrush="Black" BorderThickness="1">
<DockPanel x:Name="dPanel" Background="White">
</DockPanel>
</Border>
</ScrollViewer>
</Grid>
When I use the following XAML in my MainWindow.xaml:
<local:UserDockPanel>
<Label ...>
<Label ...>
</local:UserDockPanel>
It says I can't have more than one child.
My first question is: Should I be using a UserControl or should I use a Custom Control?
I thought UserControl would be best for my situation where I have a label, and Border and Scrollviewer over my DockPanel.
Also, From my understanding a Panel can't be templated. It is look-less and therefore has no style.
Second Question: If I should be using a UserControl, how can I make it so more than one child is allowed to be added into the dock panel?
You can do that with an ItemsControl, no need to subclass anything or create your own:
<Window x:Class="WpfApplication4.Window16"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window16" Height="300" Width="300">
<Window.Resources>
<Style TargetType="ItemsControl" x:Key="UserDockPanelStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ItemsControl">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Label Grid.Row="0" Content="USER CONTROL" HorizontalAlignment="Stretch" HorizontalContentAlignment="Center" Name="label1"
VerticalAlignment="Top" FontSize="26" Padding="0"/>
<ScrollViewer Grid.Row="1" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled">
<Border BorderBrush="Black" BorderThickness="1">
<ItemsPresenter/>
</Border>
</ScrollViewer>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="ItemsPanel">
<Setter.Value>
<ItemsPanelTemplate>
<DockPanel IsItemsHost="True" Background="White"/>
</ItemsPanelTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<ItemsControl Style="{StaticResource UserDockPanelStyle}">
<Label DockPanel.Dock="Bottom" Content="Bottom"/>
<Label DockPanel.Dock="Top" Content="Top"/>
<Border Background="Blue"/>
</ItemsControl>
</Window>
