Did you try the demo form I just posted? It does exactly that.

Here is a more complete version that shows how to move items in both directions with clicks or with buttons. It can move one, ten or all items on a click.

This demo shows how to use relational list techniques with a listbox.

here is the code that does what I want. Thank you for your help.

$buttonClearSelectedSun_Click={

$selectedCount = $lb_sun.SelectedItems.Count
for($selectedCount;$selectedCount -ge 1; $selectedCount--)
{
$idx = $lb_sun.SelectedIndex
$lb_sun.Items.RemoveAt($idx)
}

}

Sorry but that code will not work as you think it will. It is basically doing nothing in a loop.

You loop does many executions of the same item.

$idx=$lb_sun.SelectedIndex
$lb_sun.Items.RemoveAt($idx)

This should do what you want:

while($idx=$lb_sun.SelectedIndex){
$lb_sun.Items.RemoveAt($idx)
}

In your is index is null you will blow up.
