That is one of the object button, I got the value 45 which is the property value of the property name "Index" using the Object Spy.
So in this case there're a lot of check boxes and radio buttons (there are like hundreds of them) that arranged in rows and columns.
One of the test case is that I need to make the testing for each desired rows only.
Using the Object Spy, i figured that the property value of the property name "Index" of the buttons in the same row is in sequence (for example in row 5, there are 9 buttons with the property value of the property name "Index" are: 37,38,39,40,41,42,43,44,45).
Therefore I plan to use loop with FindChild to taking care of the mapping, but the loop i made before is not working.
