The Sampler function takes one argument. This is a JigPrompts of  EditorInput. JigPrompts is used in the Sampler function to control what happens when the entity is being dragged. For example you can use the AcquirePoint function of the JigPrompts to get a point or use the AcquireDistance method to get a distance from the user.  The Sampler Function Returns a SamplerStatus Emumeration. You need to determine the value of the SamplerStatus to return. If  the location of the drag has not changed you return SamplerStatus.NoChange. Doing this will stop the drag image from doing excisive flickering. Remember that these functions are continuously called during the drag. If there is a change in the location of the drag you return SamplerStatus.OK.
