Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.

Remarks

If elements is null then all elements are removed.
If a group element is provided in the list of elements to be removed then the group element and all its children will be removed.
If a child of a group element is provided in the list in addition to its parent then the parent takes precedence (i.e. the entire group element is removed and not just that child).
The map view displaying the graphics layer should be initialized.

//on the QueuedTask      
graphicsLayer.RemoveElements(graphicsLayer.GetSelectedElements());
