Get Selected Item Of ListBox using ContextMenu

Question

I am working on WPF. I have ListBox and I am adding ListBox Items programatically through "ObservableCollection" as I have to add and remove at runtime. I am having ContextMenu on ListBoxItems. Now I want to get the selected item by clicking on the contextmenu. Here is my code:

.cs

    ObservableCollection<string> MyItems = null;

    public MessageTrcr()
    {
        InitializeComponent();

        MyItems = new ObservableCollection<string>();

        listofConnectedItems.ItemsSource = MyItems;

        CreateListItem("Sandeep");
        CreateListItem("Gopi");
    }

    public void CreateListItem(String ItemName)
    {
        MyItems.Add(ItemName);
    }
    private void MenuItemStart_Click(object sender, RoutedEventArgs e)
    {
        // What should I write here to get selected Item
    }

and .xaml

<Grid>
    <ListBox x:Name="listofConnectedItems" Grid.Column="0" Grid.Row="0" ItemsSource="{Binding MyItems}"  >
        <ListBox.ItemContainerStyle>
            <Style TargetType="{x:Type ListBoxItem}">
                <Setter Property="Padding" Value="10">
                </Setter>
            </Style>
        </ListBox.ItemContainerStyle>
        <ListBox.ContextMenu>
            <ContextMenu x:Name="contextMenu">
                <MenuItem Header="_Start" Click="MenuItemStart_Click" />
                <MenuItem Header="Sto_p"  />
                <MenuItem Header="_Clear" />
            </ContextMenu>
        </ListBox.ContextMenu>
    </ListBox>
</Grid>

Here is the screenshot.

When I right click on Gopi and click on Start I want "Gopi" in MenuItemStart_Click

Now what should I write in "MenuItemStart_Click" event to get the selected Item. I tried e.OriginalSource as MenuItem and sender as MenuItem but of no use. Can any one please get me through this. Thanks in advance

Why not bind the selected item property also?

 <ListBox 
    SelectedItem="{Binding SelectedItemProperty, Mode=TwoWay}"
    x:Name="listofConnectedItems" 
    Grid.Column="0" Grid.Row="0" 
    ItemsSource="{Binding MyItems}"  >

Then in your code next to your observable collection

public string SelectedItemProperty {get; set;}
