what are the codes to use to filter out my listbox as the user is typing in the textbox?

the data in my listbox is from database. I have used a relay command to get all the details of an Event then place the details in an observable collection. Then bind my listbox to the observable collection and a textblock to show the Event Names.

xaml codes:

<TextBox  x:Name="txtSearch" Background="White" FontSize="30"  Height="57" Margin="19,10,19,0" Grid.Row="1" />
<Grid Grid.Row="1" x:Name="ContentRoot" Margin="19,72,19,0">
        <ListBox Background="Black"  x:Name="listBox" FontSize="26" Margin="0,10,0,0" LayoutUpdated="listbox_layoutUpdate" ItemsSource="{Binding HomePage.SearchEventCollection}">
            <ListBox.ItemTemplate >
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <TextBlock x:Name="txtEventName" TextWrapping="Wrap" Text="{Binding EventName}" Tapped="txtEventName_Tapped" IsTapEnabled="True" Foreground="White" Width="300" Margin="10,15,0,0" Height="55"/>
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </Grid>



relay command in viewmodel:

private RelayCommand _eventSearch;

    /// <summary>
    /// Gets the EventSearch.
    /// </summary>
    public RelayCommand EventSearch
    {
        get
        {
            return _eventSearch
                ?? (_eventSearch = new RelayCommand(
                async() =>
                {
                    SearchEventCollection.Clear();
                    var eventList = await App.MobileService.GetTable<Event>().ToListAsync();

                    foreach (Event ename in eventList)
                    {
                        SearchEventCollection.Add(new Event
                        {
                            Id = ename.Id,
                            EventName = ename.EventName,
                            Date = ename.Date,
                            Location = ename.Location,
                            Desc = ename.Desc
                        });
                    }
                }));
        }
    }

    }



private static ObservableCollection<Event> _searchEventCollection = new ObservableCollection<Event>();

    public static ObservableCollection<Event> SearchEventCollection
    {
        get { return _searchEventCollection; }
        set { _searchEventCollection = value; }
    }
