.net - Powershell: How to change listbox item colors as well as change them when selected -

here's have far:

foreach($group in $userbgroups.items) {     if($_.state -eq 'selected') {         try {             $brush = new-object system.drawing.solidbrush([system.drawing.color]::lightblue)             $_.graphics.fillrectangle($brush, $_.bounds)         } {             $brush.dispose()         }     } elseif($group -eq $lbitem) {         try {             $brush = new-object system.drawing.solidbrush([system.drawing.color]::lightgreen)             $_.graphics.fillrectangle($brush, $_.bounds)         } {             $brush.dispose()         }     } } 

this works part aside case want select item colored green, seems must selecting brief second reverts green. i'm lost causing behavior.

i know if add "or" statements 'selected' logic noaccelerator end coloring rows light blue , when click on them either highlight darker blue or light green if have been color without noaccelerator.

so managed figure out solution problem. modified drawitem event following:

$userbgroups_drawitem=[system.windows.forms.drawitemeventhandler]{     #event argument: $_ = [system.windows.forms.drawitemeventargs]     if($userbgroups.items.count -eq 0) {return}     $_.drawbackground()     $lbitem = $userbgroups.items[$_.index]     $itembgcolor = [system.drawing.color]::white      if($userbgroups.selecteditems.contains($lbitem)) {         $itembgcolor = [system.drawing.color]::lightblue     } else {         if($userbgroups.items -contains $lbitem) {             $itembgcolor = [system.drawing.color]::lightgreen         } else {             $itembgcolor = [system.drawing.color]::white         }     }      try {         $brush = new-object system.drawing.solidbrush($itembgcolor)         $_.graphics.fillrectangle($brush, $_.bounds)     } {         $brush.dispose     }     $_.graphics.drawstring($lbitem, $_.font, [system.drawing.systembrushes]::controltext, (new-object system.drawing.pointf($_.bounds.x, $_.bounds.y))) } 

the key code worked missing something. whenever selected item selected different item still keep previous selection. resolve made following selection changed event:

$userbgroups_selectedvaluechanged={     $userbgroups.refresh() } 

it causes flashing occur after selecting item when redraws workable until can figure out if there's way resolve that.
