I'm rewrite default template of ListBoxItems & ListBox. Here MainWindow.xaml

Here codeBehind MainWindow.xaml.cs

public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.DataContext = new List<string>() { "123", "546", "789"};
}
private void CheckBox_Checked(object sender, RoutedEventArgs e)
{
CheckBox bik = sender as CheckBox;
DependencyObject dob = bik as DependencyObject;
while (dob.GetType() != typeof(ListBox))
{
dob = VisualTreeHelper.GetParent(dob);
}
ListBox my = dob as ListBox;
if (!my.SelectedItems.Contains(bik.DataContext))
my.SelectedItems.Add(bik.DataContext);
}
private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
{
CheckBox bik = sender as CheckBox;
DependencyObject dob = bik as DependencyObject;
while (dob.GetType() != typeof(ListBox))
{
dob = VisualTreeHelper.GetParent(dob);
}
ListBox my = dob as ListBox;
if (my.SelectedItems.Contains(bik.DataContext))
my.SelectedItems.Remove(bik.DataContext);
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
this.M.SelectedItems.Add(((IList<string>)this.DataContext)[0]);
this.M.SelectedItems.Add(((IList<string>)this.DataContext)[2]);
}
}
}
Main idea I want to achive - is to create checkable ListBox. One feature I want to have - is Select All CheckBox. But here the problem. SelectAll CheckBox is not laying inside ListBox. So its under it.
I want that focus worked like SelectAll CheckBox lay inside ListBox. It means, that when I click Tab key, focus should go to the next CheckBox. In my case, if ListBox have more than 1 item, its just change focus between two CheckBoxes - between SelectAll CheckBox and first from ListBox item. But I want it goes down to the next ListBox item. I try to play with FocusManager's properties, but nothing happens.
Any suggestion...?
