You can call Map.ZoomTo with the geometry extent of your selected graphic.
This is working well if your geometry is a line or a polygon.
If it's a point, you have to create an envelope around the point (with a size depending on the zoom level you are expecting) and call ZoomTo with this envelope.

Something like:

var env = new Envelope(point.X - size/2, point.Y - size/2, point.X + size/2, point.Y + size/2);
env.SpatialReference = point.SpatialReference;
