Powershell WPF Textbox into array - wpf

Question

I have a WPF form that opens a textbox for user input, going for a line seperated list of PC names. No matter how I try separating them the values all end coming back as a single item, a mutli-line item sure, but one item. I can't get those to go into my array one line at a time.
Here's the XAML along with a few of the things I've tried through many attempts to get this into my array. Note that the textbox.lines doesn't seem to return anything though I read that's might work for my needs.
$inputXML = #"

$TempVar = $TempVar.Trim()

#foreach ($item in $TempVar) {$Machinearray += $item}
#$TempVar = ($TempVar -split '/r?/n').Trim()
Out-GridView -InputObject $TempVar -Title "WPF Machines List"
The out-GridView displays something like this:

Thanks for any help!
Update: I am trying to get a list of machines back from the Textbox to run through a set of command for each machine name, I have tried all kinds of string manipulation and cannot get the list as individual items it comes back as a single item from the textbox. For my XAML, I use VS to get this xaml code and powershell around it to launch it and modify it. E.g. I have powershell getting a list of groups from an OU, and use that to populate the combobox, then the list of machines would be added to the selected group, so there is no more to the xaml code itself than this. Here's the full xaml function if that helps determine what I'm doing wrong.

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

Answer 1

You had everything needed:
a trimed string
a split for [environment]::NewLine
[System.StringSplitOptions]"RemoveEmptyEntries" to get rid of empty lines.
Put it together and the line looks like this:
$TempVar = ($WPFMachinesList.Text.Trim()).split([environment]::NewLine,[System.StringSplitOptions]"RemoveEmptyEntries")
This will create an array from the lines you entered in the textbox.
