Here is the ListBox.ItemTemplate:

All items load ok and I can get the items out when item in listbox is selected. I just do not know how to tell if the checkbox is checked or how to make it check. I hope someone can help. If you need more info on this let me know.

Thanks In Advance:

Hello Ray,

Try in this way

You can define a model like this

public class Model
{
public string Content { get; set; }
public bool IsSelected { get; set; }
}

and bind it to the checkbox

var data = new List()
{
new Model{ Content = "item1", IsSelected = false},
new Model{ Content = "item2", IsSelected = false},
new Model{ Content = "item1", IsSelected = false},
new Model{ Content = "item3", IsSelected = false}
};

SendCodecsNamelistBox.ItemsSource = data;

Then you can get what you want like this

var selectedContents = data.Where(i => i.IsSelected)
.Select(i => i.Content)
.ToList();

Another Way:

It would probably be best to bind the CheckBox to the IsSelected property of the ListBoxItem, like so:
