How to horizontally align controls?

I'm trying to align below controls horizontally by keeping the label and the combobox on the left and both buttons on the right. I've tried different approaches using StackPanel but nothing gives me the desired output. Appreciate if you guys could point out what am I doing wrong here?
Current Layout
XAML source
<StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Center" Orientation="Vertical" Margin="0,0,0,2" >
<StackPanel Orientation="Horizontal" VerticalAlignment="Center">
<StackPanel HorizontalAlignment="Left" Orientation="Horizontal" VerticalAlignment="Center">
<Label Content="Age Bucket" HorizontalAlignment="Left" VerticalAlignment="Center" />
<ComboBox HorizontalAlignment="Left" VerticalAlignment="Center" Margin="10,0,0,0" Width="100"
SelectedValue="{Binding SelectedAgeBucket}"
DisplayMemberPath="DisplayMember" SelectedValuePath="ValueMember"
ItemsSource="{Binding AgeBuckets}" IsSynchronizedWithCurrentItem="True"/>
</StackPanel>
<StackPanel HorizontalAlignment="Right" VerticalAlignment="Center" Orientation="Horizontal" Margin="0,0,0,2">
<Button Click="Button_Click_1" Content="Export" HorizontalAlignment="Right" />
<Button HorizontalAlignment="Right" VerticalAlignment="Center" Click="Button_Click_2" Content="Print" Margin="5,0" />
</StackPanel>

How can i centred a popup on my window in XAML?

i want to have a centred popup notifications on my window ( Height="400" Width="500"). See the xaml code below. Is it possible to center it only with xaml (without the code behind)?
</Grid>
<TextBlock Text="TEXT" Grid.Row="1" Grid.Column="0" Grid.RowSpan="2" Grid.ColumnSpan="3" FontSize="200" FontWeight="Bold" HorizontalAlignment="Center"/>
<Grid Grid.Row="1" Grid.Column="1">
<Popup x:Name="PopupName" Grid.ColumnSpan="2" IsOpen="{Binding ElementName=ToggleButton,Path=IsChecked}" StaysOpen="False" Placement="Absolute"
AllowsTransparency="True" PopupAnimation="None" Focusable="False" HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid Height="400" Width="500">
<Rectangle Fill="Silver" Opacity="0.5" Panel.ZIndex="1" Height="400" Width="500"/>
<StackPanel VerticalAlignment="Center" HorizontalAlignment="Center" Panel.ZIndex="2" Height="150" Width="150">
<ListBox Height="Auto" HorizontalAlignment="Center" >
<Label Content="Red" Background="Red" Margin="5" VerticalAlignment="Top"/>
<Label Content="Green" Background="Green" Margin="5" VerticalAlignment="Center"/>
<Label Content="Yellow" Background="Yellow" Margin="5" VerticalAlignment="Bottom"/>
</ListBox>
</StackPanel>
<ToggleButton Panel.ZIndex="2" Background="Coral" Foreground="White" FontWeight="Bold" Name ="Button" Width="80" Height="30" HorizontalAlignment="Center" Margin="5,170,5,5" Content="Close" Click="Button_OnClick"/>
</Grid>
</Popup>
</Grid>
Another option was to use Placement ="AbsolutePoint" with Horizon-/Verticaloffset but it seems like a bit weird :D
Any suggestion? Thx ;)

This should center the Popup in the parent window:
<Popup ...
Placement="Center"
PlacementTarget="{Binding RelativeSource={RelativeSource AncestorType=Window}}" />

Add xaml to top of Listbox

I have a listbox which is filled up with items taken from a data contract. I want to add a bit of xaml to the top of the listbox which takes data from another data contract. How do i go about doing this?

I tried just adding a new item to the listbox but the data contract would mean i have to instantiate all the sub levels of objects and it would suckkk as they are different domains.
Keep in mind that i want the entire screen to scroll in union... so that it looks like one big long list, regardless of the first being like a default value.

Put the first item outside the ListBox and disable ScrollViewer for the ListBox so the whole thing will scroll together. Here's an example where the item is a simple TextBlock. You can change it to suit your requirement.
<ScrollViewer>
<StackPanel Orientation="Vertical">
<TextBlock Text="Item 1"/>
<ListBox ScrollViewer.VerticalScrollBarVisibility="Disabled">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding item}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</ScrollViewer>

Listbox No Scrollbar

I have been up and down looking on the internet and many people seem to have this problem but its generally solved by changing the container to a grid, constraining the height etc. etc. I can't to seem to get this to work.
I have an observableCollection thats feeding into a DataTemplate. I can't for th life of me get the scrollbar working. Its there but not enabling. Thanks Scott

Must be a bug. I have the following only..
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="ComfortReportEng.Views.EngineerReport.EngineerReport"
Title="Engineer Report" WindowStartupLocation="CenterScreen" Loaded="Window_Loaded" SizeToContent="WidthAndHeight" >
<Window.Resources>
<CollectionViewSource x:Key="cvsReportList"/>
</Window.Resources>
<Grid Margin="0.125,0.412,3.125,0" Height="471">
<ListBox Margin="23,64,3,0" Width="834.14" ItemsSource="{Binding Source={StaticResource cvsReportList}}"
x:Name="lbReportList" SelectionChanged="lbReportList_SelectionChanged" Background="#FFEEEFE4" />
</Grid>
and code is
private void LoadReportList()
{
int number = 0;
List<int> myNumbers = new List<int>();
while (number < 80)
{
myNumbers.Add(number);
number += 1;
}
_cvsReportList = (CollectionViewSource)(this.FindResource("cvsReportList"));
_cvsReportList.Source = myNumbers;
}
This was copied over from another project. Completely confused. Please don't worry. It's not a logical problem. Please take this as a close call with no solution. Cheers again Scott
Just to give this completeness. I am not sure why this happens but here is it.
if (System.Environment.MachineName == "SCOTT-PC")
{
this.txtUserName.Text = "Scott Fisher";
this.txtPassword.Password = "palace";
//LoginOK();
}
else
Keyboard.Focus(this.txtUserName);
If I clear the comments on LoginOK procedure I will get no scrollbar. With it commented and I interact with the login screen then everything is fine. Finally here is the code for the LoginOK.
if (LoginService.CheckLogin(txtUserName.Text, txtPassword.Password.ToString()))
{
Helpers.User.ThisUser = this.txtUserName.Text;
EngineerReport.EngineerReport engReport = new EngineerReport.EngineerReport()
{
Owner = Window.GetWindow(this),
WindowStartupLocation =
System.Windows.WindowStartupLocation.
CenterOwner
};
this.Hide();
engReport.ShowDialog();
}
else
{
this.txtPassword.Password = "";
this.txtPassword.Focus();
}

Can you provide you DataTemplate as I believe I have just managed to mock up what you are trying to achieve and I have scrollbars visible and working form the start.
Here is the xaml that I used for the DataTemplate for the ListBox:
<ListBox DataContext="{StaticResource MusicData}" ItemsSource="{Binding XPath=Album}">
<ListBox.ItemTemplate>
<DataTemplate>
<ListBoxItem>
<StackPanel Orientation="Horizontal" >
<TextBlock>No.</TextBlock>
<TextBlock Text="{Binding XPath=No}"></TextBlock>
<TextBlock>Title</TextBlock>
<TextBlock Text="{Binding XPath=Title}"></TextBlock>
</StackPanel>
</ListBoxItem>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Hope this helps.
I also found a piece of code I used a while back and this might help. You can try setting the ItemsPanelTemplate:
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel>
<ScrollViewer VerticalScrollBarVisibility="Visible" />
</StackPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
This will work with any items control as stated in this article:
http://msdn.microsoft.com/en-us/library/system.windows.controls.itemscontrol.itemcontainerstyle.aspx
One final thing I can suggest is to create your own ControlTemplate for the ListBox Like so:
<ListBox.Template>
<ControlTemplate>
<ScrollViewer VerticalScrollBarVisibility="Auto">
<ItemsPresenter />
</ScrollViewer>
</ControlTemplate>
</ListBox.Template>

Splitting Button in Half

I'm trying to split a button in half so that I can show text data in each half - which can also be increased in size when the application is expanded.
This is the code I've got soo far.
<Button Margin="16,0,16,6" Background="#daf0fc" BorderThickness="0" Height="Auto" HorizontalAlignment="Stretch" BorderBrush="White" Click="edit_house" Padding="0" Focusable="False">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Orientation="Vertical" VerticalAlignment="Top" HorizontalAlignment="Left" Background="Black">
<StackPanel Orientation="Horizontal">
<TextBlock Margin="0,0,5,0" Text="{Binding house_number}" FontWeight="Bold" FontSize="14" />
<TextBlock Margin="0,0,0,0" Text="{Binding street}" FontWeight="Bold" FontSize="14" />
</StackPanel>
<TextBlock Text="{Binding postcode}" />
<TextBlock Margin="0,6,0,0" Text="{Binding house_type_text}" />
</StackPanel>
<StackPanel Grid.Column="1" Orientation="Vertical" VerticalAlignment="Top">
<StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="0,2,0,0">
<TextBlock Text="£" HorizontalAlignment="Right" Foreground="#FF9D1818" FontWeight="ExtraBold" FontSize="16" />
<TextBlock Text="{Binding house_price}" HorizontalAlignment="Right" Foreground="#FF9D1818" FontWeight="ExtraBold" FontSize="16" />
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left" Margin="0,0,0,0">
<TextBlock Margin="0,0,0,0" Text="{Binding sold_text}" HorizontalAlignment="Right" Foreground="#FF107910" FontWeight="ExtraBold" FontSize="14" />
</StackPanel>
</StackPanel>
I've tried setting each StackPanel half to stretch, but they both just Float in the centre of the button, so I can't align the text on either half.
Here's a graphical representation of the button I'm trying to create...
Update:
Here is what I'm getting with the code above, sadly I'm struggling to get the text to align, or to get anything to stretch to the full width of each half:

StackPanel won't do that; it just stacks elements.
Instead, use a <Grid> with two columns.

StackPanel is not the right container for this. Try using a Grid like this:
<Button>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0">
...
</StackPanel>
<StackPanel Grid.Colunn="1">
...
</StackPanel>
</Grid>
</Button>

I like to use UniformGrids, although a Grid will also work if you need to define your Rows/Columns individually
Here's an example, with correct alignments:
<UniformGrid Columns="2">
<StackPanel Background="LightBlue" >
<StackPanel Orientation="Horizontal">
<TextBlock Margin="0,0,5,0" Text="123" FontWeight="Bold" FontSize="14" />
<TextBlock Margin="0,0,0,0" Text="Main Street" FontWeight="Bold" FontSize="14" />
</StackPanel>
<TextBlock Text="12345" />
<TextBlock Margin="0,6,0,0" Text="Type" />
</StackPanel>
<StackPanel Background="Yellow">
<StackPanel Orientation="Horizontal" VerticalAlignment="Top" Margin="0,2,0,0" HorizontalAlignment="Right">
<TextBlock Text="£" HorizontalAlignment="Right" Foreground="#FF9D1818" FontWeight="ExtraBold" FontSize="16" />
<TextBlock Text="100.00" HorizontalAlignment="Right" Foreground="#FF9D1818" FontWeight="ExtraBold" FontSize="16" />
</StackPanel>
<TextBlock Margin="0,0,0,0" Text="200.00" HorizontalAlignment="Right" Foreground="#FF107910" FontWeight="ExtraBold" FontSize="14" />
</StackPanel>
</UniformGrid>
