How to add empty UserControl of StackPanel programmatically in WPF

I have a UserControl, empty StackPanel like following.
<Grid>
<StackPanel x:Name="datawrapper" Orientation="Horizontal" Background="Yellow"/>
</Grid>
Main window's XAML is like following.
<ScrollViewer Grid.Row="2" Grid.Column="0" Background="Gray">
<StackPanel x:Name="holderpanel" Orientation="Vertical"/>
</ScrollViewer>
I want to put datawrapper into holderpanel from the Main Window's code behind programmatically.
If there's control in the datawrapper, dadawrapper is inserted into holder panel.
However, in case of empty StackPanel, never inserted.
How to do this?

To help you clarify your question, I'll provide an example of exactly what you asked for:
<Grid>
<ScrollViewer Grid.Row="2" Grid.Column="0" Background="Gray">
<StackPanel x:Name="holderpanel" Orientation="Vertical"/>
</ScrollViewer>
<Grid>
<StackPanel x:Name="datawrapper" Orientation="Horizontal" Background="Yellow">
<TextBlock Text="Test"/>
</StackPanel>
</Grid>
</Grid>
codebehind (for this example, I added to Loaded event handler, but it could be used elsewhere):
private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
if (datawrapper.Children.Count > 0)
{
var grid = datawrapper.Parent as Grid;
grid.Children.Remove(datawrapper);
holderpanel.Children.Add(datawrapper);
}
}

The datawrapper should be separated user control and empty like following.
<Grid>
<StackPanel x:Name="datawrapper" Orientation="Horizontal" Background="Yellow"/>
</Grid>
I will add another user controls into the datawrapper horizontally 5 later. That user control is like following.
<UserControl x:Class="WpfTest.ResultItem"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

mc:Ignorable="d"

<Grid x:Name="resultitem">
<Border CornerRadius="5" BorderBrush="#e0e0e0" Background="White" BorderThickness="2" DockPanel.Dock="Top" Margin="10 10 10 15">
<Grid Margin="0 30 0 30" Background="White">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="Chart#" Width="Auto" Height="30" Margin="5 5 0 5" FontSize="20" VerticalAlignment="Center"></TextBlock>
<TextBlock Grid.Row="1" Grid.Column="0" Text="Patient Name" Width="Auto" Height="Auto" Margin="5 5 0 5" FontSize="20" VerticalAlignment="Center"></TextBlock>
<TextBlock Grid.Row="2" Grid.Column="0" Text="Home Phone#" Width="Auto" Height="Auto" Margin="5 5 0 5" FontSize="20" VerticalAlignment="Center"></TextBlock>
<TextBlock Grid.Row="3" Grid.Column="0" Text="Cell Phone#" Width="Auto" Height="Auto" Margin="5 5 0 5" FontSize="20" VerticalAlignment="Center"></TextBlock>
<TextBlock Grid.Row="4" Grid.Column="0" Text="Patient Type" Width="Auto" Height="Auto" Margin="5 5 0 5" FontSize="20" VerticalAlignment="Center"></TextBlock>
</Grid>
</Border>
</Grid>
If the datawrapper is filled with 5 ResultItems, datawrapper will added into the holderpanel vertically.

how to update xaml in uwp

I have created a application for windows 10 (uwp) devices. I´m using the windows appstudio "designer". Now, I have to update the source code by a combobox and the correct eventhandler.
The combobox items contains different urls. After the selection changed, I have to parse entries from a url.

Silverlight - TabControl refusing to fill remaining space

At my wits end with trying to get a TabControl and TabItems to fill a NavigationPage/Frame.
I have a MasterPage, with a Frame, that will get swapped out for different Pages, which are comprised of UserControls.
The problem I am having is that the TabControl is cutting off the UserControl and not auto sizing properly. Below is an image and the source for the Pages and Controls.

Native ComboBox not displaying choices correctly

EDIT: It seems that ListPicker is the way to go but I have had further problems with that detailed Microsoft.Phone.Controls.Toolkit ListPicker throws XamlParseException
I have the following ComboBox in code:
<ComboBox x:Name="Result" Grid.Column="6" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="Black" Background="White">
<ComboBoxItem Content="Win" />
<ComboBoxItem Content="Place" />
<ComboBoxItem Content="Lose" />
</ComboBox>
But it does not display as I would have expected. When you drop down the ComboBox the options don't appear, it's just like empty items. See below:
However, when an item is selected, it displays correctly and the correct index/item is returned. See below:
I'm sure there is something simple I have missed but can't put my finger on it.
EDIT: Ok I am posting the full code for this. I have a user control, OddsRow, that looks like this:

Separately the ComboBox works, and also the code for the OddsRow works as expected... separately. When combined it doesn't display the items.
OddsRow.xaml.cs
public partial class OddsRow : UserControl
{
private int m_Row;
public OddsRow()
{
InitializeComponent();
}
public int Row
{
get
{
return m_Row;
}
set
{
m_Row = value;
RowNumber.Text = m_Row + " - ";
}
}
}

For the love of everything, please do not use the stock ComboBox. Use something like ListPicker. It will make your application look more consistent with the Metro UI.
