What's the strongest refresh method available to ArcEngine?

Question

I have five layers: polygon, line, and point with a single IRasterLayer file. I am programmatically setting the ILayer.Visible attribute for the Raster but the layer is not refreshing. If I zoom in, or zoom out, then it refreshes properly.

I tried these two methods:

mapControl.Refresh();
mapControl.Refresh(esriViewDrawPhase.esriViewAll, null, null); 

But they didn't refresh my map. What method is stronger that this for refreshing the entire map?

Answer 1

Apparently mapcontrol.ActiveView.Refresh() is more reliable.
