Hi,

The new event args gives you all the chart objects that were updated, not just one object, because multiple objects can be updated at the same time.

To find the object that you are looking for you can use Linq, ex:

        private void Chart_ObjectsUpdated(ChartObjectsUpdatedEventArgs obj)
        {
            var verticalLine = obj.ChartObjects.FirstOrDefault(iObject => iObject.ObjectType == ChartObjectType.VerticalLine
                && iObject.Name.Equals("VerticalLine_name", StringComparison.OrdinalIgnoreCase));

            if (verticalLine != null)
            {
            }
        }

Here I check if there is an updated object that's vertical line and its name is "VerticalLine_name", if there is such an object we will get it otherwise the result will be null.
