How to use pickcontext to trigger the OnPick event of a RhinoObject?

var activeView = e.View.ActiveViewport;
var xf = e.View.ActiveViewport.GetPickTransform((int)activeView.WorldToClient(pt).X, (int)activeView.WorldToClient(pt).Y);
var pickcontext = new Rhino.Input.Custom.PickContext
{
PickStyle = Rhino.Input.Custom.PickStyle.PointPick,
};
pickcontext.SetPickTransform(xf);
var obj = Display.Doc.Objects.PickObjects(pickcontext);

I have a GripObject which I would like to expand a bit its selection detection. I am trying to use the above code to trigger its OnPick event in a MouseCallback, but it didn’t trigger.
What is missing here?

can anyone help me with this?
@dale ?

I don’t know what this means, and your code doesn’t make any sense to me.

Can you explain a little more on what you are trying to do and why?

Thanks,
