          <ListBoxItem>                                        
              <TextBlock  Text="{Binding Name}"></TextBlock>
              <Button ToolTip="Invite To Play" x:Name="btn_InviteToPlay" Click="btn_InviteToPlay_Click>

   <ListBox>

on the buttons click event i need to get the value of Player that is bound to this
listboxitem (the one containing the button which was clicked )

  private void btn_InviteToPlay_Click(object sender, RoutedEventArgs e)
  {
      Button btn = (Button)sender;
      // how to retrieve player bound to current listboxitem ?   
  }

Answer 1

btn.DataContext should already contain the Player as the DataContext is inherited by controls in the ListBoxItem.
