Hello, I'm trying to unselect selected item in ListBox, but I have no success yet ( UI ListBox still selected).
I am trying in this way:
private void OnStandarBoxSelectionChanged(object sender, SelectionChangedEventArgs e)
{
 
    if (StandardBox.SelectedItem == null) return;
 
    ...
 
    StandardBox.SelectedItem = null;
}

Could you explain What better way to solve this problem?
Thank You.

People, listen. I'm sick and tired of my waiting for your reply. I don't see the actual reason of my waiting too long. Can you answer me, why should I pay my money for nothing?

Hi Ita,

We have tested the described scenario and it does work as expected, set SelectedItem to null clears the selection of the ListBox. Please see attached our test project demonstrating the exact approach.

Hope this helps.

It doesn't work. I tested under VS 2019. Is it a bug?

Hello Uli,

I tested the application Kalin has provided but it works as expected on my end. I tested it with VS 2019, with old and new binaries. Attached, you can find a .gif file demonstrating my experience.

Could you please elaborate on the issues you're having?

Looking forward to your reply.
