Add controls(textbox) dynamically on button click in wp7 ???

Question

This is Praveen.  Thanks for your help and support provided for my previous problem.

I am doing a small project of my own with help of the project which was given here( sample name : workingwithwp7).

I'm sooo thankful for the person for giving that sample project with that i was able to learn and do my project so far very good.

My current problem is to add controls dynamically on tapping/clicking a button. I did some research on this problem and wasn't much help of it. 

Please provide me with a solution/idea/if possible a sample for adding controls dynamically in the screen would a very helpful to me. 

Thanks in Advance.
