Disable a named item in XAML with PowerShell

Hello,

Here is a function I wrote for my current script, to create user in Active Direcotry with a GUI in XAML, and which will disable a named item in the XAML.

Function Disable-NamedItem {
    [CmdletBinding()]
    Param(
        [String[]]$Item,
        [Object]$Window = $Window
    )
    foreach ($object in $Item) {
        $Window.$object.IsEnabled = $false
    }
}
