PowerShell and XAML data binding - wpf

Question

I'm trying to get a list of users searching by a surname property and list them in the ListView.
Here's XAML code:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
Title="Find users with SamAccountName"
Width="525"
Background="#FF262626"
ResizeMode="NoResize"
SizeToContent="Height">
<StackPanel Margin="5,5,5,5" Orientation="Vertical">
<Grid
Name="Grid"
Width="400"
Height="200"
Background="#313130">
<Label
Name="Label"
Content="Select employee"
FontSize="12"
Foreground="White" />
<ListView
Name="ListView"
Margin="0,25,0,0"
Background="Transparent"
BorderBrush="Transparent"
Foreground="White"
IsHitTestVisible="False"
SelectionMode="Single">
<ListView.View>
<GridView>
<GridViewColumn
Width="100"
DisplayMemberBinding="{Binding Path=Logon}"
Header="Logon" />
<GridViewColumn
Width="150"
DisplayMemberBinding="{Binding Path=FirstName}"
Header="First name" />
<GridViewColumn
Width="150"
DisplayMemberBinding="{Binding Path=LastName}"
Header="Last name" />
</GridView>
</ListView.View>
</ListView>
</Grid>
<StackPanel HorizontalAlignment="Right">
<Button Width="50" Content="SAVE" />
</StackPanel>
</StackPanel>
And it looks like this:
XAML look
I believe I cannot do it without data-binding and I saw a lot of posts about them but I couldn't understand it completely.
For now in powershell I have:
Add-Type -AssemblyName PresentationFramework
$employees = Get-ADUser -Filter {Surname -like "surname"}
$itemSource = #()
ForEach ($employee in ($employees | Sort-Object SamAccountName)) {
$itemSource += [PSCustomObject]# {
Logon = $employee.Name
FirstName = $employee.GivenName
LastName = $employee.Surname
}
$columnOrder = 'Logon', 'FirstName', 'LastName'
[XML]$Form = Get-Content "xmlPath"
$NR = (New-Object System.Xml.XmlNodeReader $Form)
$Win = [Windows.Markup.XamlReader]::Load($NR)
$Win.ShowDialog()
Now, the ForEach is working perfectly fine and returning exactly what I need but cannot find any way to put it into ViewList.
Then I'll need to save the selected user into a variable that I'll display later in the textbox.
Sorry if it's a stupid/easy question but I just started learning PowerShell to help me automate my work.

In the loaded form, you have to specify the ListView's ItemsSource
in PowerShell, you can do it like this
Add-Type -AssemblyName PresentationFramework
$employees = Get-ADUser -Filter {Surname -like "surname"}
$itemSource = #()
ForEach ($employee in $($employees | Sort-Object SamAccountName)) {
$itemSource += [PSCustomObject]#{
Logon = $employee.Name
FirstName = $employee.GivenName
LastName = $employee.Surname
}
}
[XML]$Form = (Get-Content "C:\temp\test.xaml")
$NR = (New-Object System.Xml.XmlNodeReader $Form)
$Win = [Windows.Markup.XamlReader]::Load($NR)
# this part
($win.FindName("ListView")).ItemsSource = $itemSource
$Win.ShowDialog()
