Stretch Usercontrol in Dockpanel

I'm new at WPF. I know from Forms that i can add usercontrols to a panel. How can I do this in WPF? I tried a Grid, DockPanel and StackPanel but I don't know how can I stretch my usercontrol? In this Grid oder what else will only be this usercontrol.
I need to switch the content of the grid or else because I want to display different usercontrols.

Add Usercontrol:
private void miTestbutton_Click(object sender, RoutedEventArgs e)
{
Invoice invoice = new Invoice();
invoice.HorizontalAlignment = HorizontalAlignment.Stretch;
invoice.VerticalAlignment = VerticalAlignment.Stretch;
dpContent.Children.Add(invoice);
}

The declaration of the UserContol is setting hard coded values for Width and Height, which means that the control cannot resize itself.
If you replace those two attributes with d:DesignWidth and d:DesignHeight then those values become "design-time only" values, so those values will be used when you view the control in the Visual Studio designer, but not by the application at run-time...

how to bind the Textbox outside the ItemControl

Is it possible to bind the textbox outside the itemssource of itemcontrol.
I Just start coding wpf so I don't have any idea.
This is my code:
<Page x:Class="InformationSys.View.Page1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:InformationSys.View"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300"
Title="Page1"
DataContext="{Binding Information, Source={StaticResource Locator}}">
<ItemsControl ItemsSource="{Binding Gender}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".4*"/>
<ColumnDefinition Width=".3*" />
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<CheckBox IsChecked="{Binding IsChecked}" FlowDirection="RightToLeft" Grid.Column="0" VerticalAlignment="Bottom">
<TextBlock Text="{Binding Gen_Type}"/>
</CheckBox>
<TextBox x:Name="textBox5" Grid.Column="1" Grid.Row="4" Margin="20 0 0 0" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Page>
Thanks!

Observable Collection to Tabcontrol binding

<TabControl HorizontalAlignment="Stretch" TabStripPlacement="Left" Margin="10,20,0,0" Name="tabControl2" ItemsSource="{Binding NotesObs}" VerticalAlignment="Stretch" MinHeight="80">
<TabItem Header="Contract Read and understood, proposal letter read and understood." Name="tabItem2" FontSize="14" IsEnabled="True">
<Grid>
<Border Name="b_desc"/>
<TextBox HorizontalAlignment="Stretch" Margin="0" Name="textBox5" Text="{Binding ContractText}"
VerticalAlignment="Stretch" FontSize="12" TextWrapping="Wrap"
AutoWordSelection="True" VerticalScrollBarVisibility="Auto"
AcceptsReturn="True"
Width="{Binding ElementName=b_desc, Path=ActualWidth}"
Height="{Binding ElementName=b_desc, Path=ActualHeight}"
MaxWidth="{Binding ElementName=b_desc, Path=Width}"
MaxHeight="{Binding ElementName=b_desc, Path=Height}" />
</Grid>
</TabItem>
</TabControl>
Above is my Xaml and the name of my ObsCollection is
public ObservableCollection<NotesDisplay> NotesObs { get; set; }
I have declared properly the ContractText column in the NotesDisplay Model. I cant get this to bind for some reason but this works in a datagrid. Can someone explain what I am doing wrong in my XAML?
Thanks
Edit: I have viewed the linked solution but tabs arent showing up when I run the program. They do showup in the display in xaml
<UserControl x:Class="CAT_Application_WPF.UI.NotesPage"

<Grid.RowDefinitions>
<RowDefinition Height="60*"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="300"></ColumnDefinition>
<ColumnDefinition Width="400"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TabControl HorizontalAlignment="Stretch" ItemsSource="{Binding NotesObs}" TabStripPlacement="Top" x:Name="_tabControl" VerticalAlignment="Stretch" MinHeight="80" Grid.ColumnSpan="2" Margin="121,28,279,-28">
<TabControl.ItemTemplate>
<DataTemplate>
<TextBlock>
<TextBlock Text="{Binding ContractText}"/>
</TextBlock>
</DataTemplate>
</TabControl.ItemTemplate>
<TabControl.ContentTemplate>
<DataTemplate>
<TextBlock>
This is <TextBlock Text="{Binding EMSText}"/>
</TextBlock>
</DataTemplate>
</TabControl.ContentTemplate>
</TabControl>
</Grid>
</UserControl>

Now it's quite ok but you must remove your TextBlock inside another TextBlock stuff.
You can change
<TextBlock>
<TextBlock Text="{Binding ContractText}"/>
</TextBlock>
to
<TextBlock Text="{Binding ContractText}"/>
And
<TextBlock>
This is <TextBlock Text="{Binding EMSText}"/>
</TextBlock>
to something similar to
<StackPanel Orientation="Horizontal">
<TextBlock>This is</TextBlock>
<TextBlock Text="{Binding EMSText}"/>
</StackPanel>

Can't put a window in a style

I made an mvvm project in WPF.
However, I get an error in my MainWindow.xaml, saying I can't put a window in a style...
This is my MainWindow.xaml:
<Window x:Class="DataValidation.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

</Window.DataContext>
<Window.Resources>
<DataTemplate DataType="{x:Type vm:AccountVM}">
<v:HomePage/>
</DataTemplate>
</Window.Resources>
<Grid>
<ContentControl Content="{Binding CurrentPage}"/>
</Grid>
</Window>
the error occurs on <v: HomePage>
In my HomePage.xaml I don't use the <window> tags ... So I have no idea what the actual problem could be:
