I want to demo alarm situation. When new alarm arrived, the alarm point flicker. But I cannot find a method to refresh single point. I can only find a method to refresh a whole layer, like this:


I want to change the style like this:

foreach (VectorLayerData vdata in vectorData[layerID])
                if (vdata.ID == itemID)

how can i notify the UI to refresh?
