Pass variable to XAML

Question

Windows 7, PowerShell 5

In Bruce Payette's book "Windows Powershell In Action" (2) on page 754 there is a WPF example called "Building a file search tool".

I need to modify the ComboBox (originally a TextBox) in the XAML by passing in PowerShell variables $pwd and [Environment]::GetFolderPath("MyDocuments") by using something like:

<Label Width="100" >Path to Search</Label>
<ComboBox Name="Path" Width="324" Height="23" IsEditable="True">
    <ComboBoxItem >d:\files</ComboBoxItem>
</ComboBox>

$path = $form.FindName("Path")
$path.DropDown = $pwd

Is there a way to do this please?

You can specify variable to XAML definition, like this:

 <Label Width="100" >Path to Search</Label>
       <ComboBox Name="Path" Width="324" Height="23" IsEditable="True">
          <ComboBoxItem >d:\files</ComboBoxItem>
          <ComboBoxItem >$pwd</ComboBoxItem>
          <ComboBoxItem >$([Environment]::GetFolderPath("MyDocuments"))</ComboBoxItem>
       </ComboBox>

Many thanks; but this is not interpreted, ie it shows as the literal _$pwd_. – Archdeacon Nov 17 '16 at 13:10
