How to drag and drop the family symbol object to current document like we do in Project browser ?

[jeevanandanj]

i am creating a plugin with c#. i want to drag and drop the plant family into current document.

i have seen we can able to drag and drop the family object from project browser. 

i can see the CreateInstance option when we right click the family symbol object.

This above highlighted option also doing the same thing which is adding the family symbol object to plus sign cursor.
