Solution 1

When are you trying to show the value? Looks like you are missing an event.

Steps:
1. UI has radio button and 2 textbox for input and one for result and one button for show result
2. Select radibutton, put values in two textboxes and click show result button.
3. On button click event, put the above code and you can see the computed result in result textbox.

Nothing happened. I put a break point on the routine I wrote but nothing happened

What do you mean by nothing happened? It never hit the breakpoint?
