[Question]Update WPF ListBox Items based on user input.

I’m having trouble on how to go about filtering the list of AD groups that show, imported CSV, based on what the user types. I start by populating the listbox which works fine.

The issue comes when trying to update list based on a TextChanged Event when the user starts typing in the textbox. Can anyone point me to some resources on this?

Here’s the code I have now. Most of it is commented out from trying various things. I got close-ish with one of the foreach loops but it still wasn’t filtering properly. Adding multiple entries and not fully removing items.

$groups = @(Import-Csv -Path "C:ADGroupList.csv") #$WPFlistBox.Items.Add($groups.Name) foreach ($group in $groups){ $WPFlistBox.Items.Add($group.Name)# | where { $_ -like "*$($WPFtextBoxSearchGroups.Text)*" } -join "`r`n" } $WPFtextBoxSearchGroups.Add_TextChanged({ #foreach ($group in $groups){ #$WPFlistBox.Items.Remove(($groups.Name | ? { $_ -notlike "*$($WPFtextBoxSearcgGroups.Text)*" }) -join "`r`n") #} #foreach ($group in $groups){ #$WPFlistBox.Items.Add($group.Name) | where { $_ -like "*$($WPFtextBoxSearchGroups.Text)*" } -join "`r`n" #} #ForEach ($group in $groups){ # If( $_ -like "*$($WPFtextBoxSearchGroups.Text)*"){ # $WPFlistBox.Items.Add($groups.Name) # } # Else{ #If($_ -notlike "*$($WPFtextBoxSearcgGroups.Text)*"){ # $WPFlistBox.Items.Remove($groups.Name) # } ##} $WPFlistBox.Items.Add(($groups.Name | ? { $_ -like "*$($WPFtextBoxSearchGroups.Text)*" }) -join "`r`n") #$WPFlistBox.Items.AddNew(($groups.Name | ? { $_ -like "*$($WPFtextBoxSearchGroups.Text)*" }) -join "`r`n") #$WPFlistBox.Items.Remove(($groups.Name | ? { $_ -notlike "*$($WPFtextBoxSearcgGroups.Text)*" })) #$WPFlistBox.Items.RemoveAt($_ -notlike "*$($WPFtextBoxSearcgGroups.Text)*") #} #$groups.Name | ForEach-Object {} })
