Question

I have an app that responds to events and adds the data from the events to a “ListView”, and I have a simple class that have 3 properties.

ListView holds this data:

    public string Code { get; set; }
    public string Status { get; set; }
    public TimeAgo Time { get; set; }

class TimeAgo is:

public class TimeAgo
{

    private DateTime _time;

    public TimeAgo(DateTime time) { _time = time; }

    public override string ToString()
    {
        return new TimeSpan(DateTime.Now.Ticks - _time.Ticks).Seconds + " seconds ago";
    }
}

so, whenever a new event is happening I want the other objects to update, so if I add a new one it says “0 seconds ago” but the old ones should be updated and say “15 seconds ago” so I can track how long ago each event happened when it’s updated.

I’ve searched for methods for this, but all I’ve tried haven’t worked.

Any ideas?

Answer 1

Just make Seconds a property you bind to.

To put at top

Insert(0, T item 

For all the items in the ObservableCollection call NotifyPropertyChanged(“Seconds”); after the insert.
