Binding WPF Listview colums with powershell pipeline for output - wpf

Question

I’m working on a PowerShell WPF GUI tool where I’m stuck with binding pipeline output to listview…I have gone through couple of blogs/articles but couldnt find way to pass pipeline output to listview columns.
I have attached code from xaml and powershell...
xaml code:
<ListView Name="listdisk" HorizontalAlignment="Left" Height="415" Margin="20,67,0,0" VerticalAlignment="Top" Width="830" Grid.ColumnSpan="3" ScrollViewer.VerticalScrollBarVisibility="Visible"> 
<ListView.View>
<GridView> 
<GridViewColumn Header="Server Name" DisplayMemberBinding ="{Binding 'ServerName'}" Width="200"/>
<GridViewColumn Header="C Disk Size(GB)" DisplayMemberBinding ="{Binding 'Csize'}" Width="105"/>
<GridViewColumn Header="C Free Space(GB)" DisplayMemberBinding ="{Binding 'Cfree'}" Width="105"/>
<GridViewColumn Header="C % Free Space" DisplayMemberBinding ="{Binding 'CPercentfree'}" Width="100"/>
<GridViewColumn Header="D Disk Size(GB)" DisplayMemberBinding ="{Binding 'Dsize'}" Width="105"/>
<GridViewColumn Header="D Free Space(GB)" DisplayMemberBinding ="{Binding 'Dfree'}" Width="100"/>
<GridViewColumn Header="D % Free Space" DisplayMemberBinding ="{Binding 'DPercentfree'}" Width="100"/>
</GridView> 
</ListView.View> 
</ListView> 
Powershell function-
Function Get-diskinfo{
$dsk=#()
$Getservers = Get-Content $dsksvr
foreach ($CompName in $Getservers)
{
$cdrivespace= Get-WMIObject Win32_logicaldisk -ComputerName $CompName | ?{$_.DeviceID -eq 'C:'} | Select #{Name=‘cTotalSize’;Expression={[int]($_.Size / 1gb)}},`
#{Name=‘cFreeSpace’;Expression={[int]($_.FreeSpace / 1gb)}}, #{Name=‘cPercentFree’;Expression={[math]::Round($_.FreeSpace / $_.Size,2)*100}}
$ddrivespace= Get-WMIObject Win32_logicaldisk -ComputerName $CompName | ?{$_.DeviceID -eq 'D:'} | Select #{Name=‘dTotalSize’;Expression={[int]($_.Size / 1gb)}},`
#{Name=‘dFreeSpace’;Expression={[int]($_.FreeSpace / 1gb)}}, #{Name=‘dPercentFree’;Expression={[math]::Round($_.FreeSpace / $_.Size,2)*100}}
$diskinfo = New-Object psobject
Add-Member -InputObject $diskinfo -membertype noteproperty -name "ServerName" -value $CompName
Add-Member -InputObject $diskinfo -membertype noteproperty -name "cSize" -value $cdrivespace.cTotalSize
Add-Member -InputObject $diskinfo -membertype noteproperty -name "cFree" -value $cdrivespace.cFreeSpace
Add-Member -InputObject $diskinfo -membertype noteproperty -name "cPercentfree" -value $cdrivespace.cPercentFree
Add-Member -InputObject $diskinfo -membertype noteproperty -name "DSize" -value $ddrivespace.dTotalSize
Add-Member -InputObject $diskinfo -membertype noteproperty -name "DFree" -value $ddrivespace.dFreeSpace
Add-Member -InputObject $diskinfo -membertype noteproperty -name "DPercentfree" -value $ddrivespace.dPercentFree
$dsk +=$diskinfo
} Return, $dsk
}
This is the part where I'm thinking am not doing it properly...can someone guide me on this please..? Thanks
$btndiskinfo.Add_Click({
get-diskinfo | % {$listdisk.items.add([pscustomobject]($_))}
})

Answer 1

Use {Binding WhatEverYouWant} instead of {Binding 'WhatEverYouWant'},
When you need to pass a custom object in a listview you can use :
$btndiskinfo.Add_Click({
$listdisk.ItemsSource = #(get-diskinfo)
})
Be sure your columns names in the listview have the same name as your custom object properties

Answer 2

I've got a work-around you can try. Instead of creating an array of PSObjects inside the foreach and adding it to the ListView after the function is over, try creating 1 PSCustomObject like you're already doing but instead add it to the ListView then and there where you call $dsk += $diskinfo
Something like:
...
Add-Member -InputObject $diskinfo -membertype noteproperty -name "DPercentfree" -value $ddrivespace.dPercentFree
$listdisk.items.add([pscustomobject]($diskinfo))
