Hi there,

 

Although this post is very informative, it didn’t quite fulfill my needs.

I needed to start an asynchronous method, lazy loading some data, when a property bound to a WPF control was updated.

This is what I came up with:

 

public void UpdateInformation(string propertyValue)
{
	System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke(new Action(async () =>
	{
		_cancellationTokens.ForEach(c => c.Cancel());
		using (CancellationTokenSource cancellationToken = new CancellationTokenSource())
		{
			try
			{
				_cancellationTokens.Add(cancellationToken);
				var dataResponse = await service.LoadData(propertyValue, cancellationToken);
				...
			}
			finally
			{
				_cancellationTokens.Remove(cancellationToken);
			}
		}
	}));
}

As always, feel free to ask or comment.
