Accessing Child Properties from the object

My Object has some child controls say text control/grid control/Chart control. The problem is in run time (ie when I insert my object into the container like word/excel/IE) the child controls in my object should able to show their properties on their right click. TO make a better understanding Ill give an example Open yur word document insert a chart control into it, now edit the chart object he will allow to view the properties for each control, I want something similar
