For question1, there will be a property called aastate when you indicate the element using UiExplorer, that property will give the correct state of the checkbox.
For question2, you can use get text activity to extract 21 from the screen and checking it or you can explore the properties of that element in the UiExplorer, I believe the text or aaname property will have the value.
@Udhay, thanks.
I use the βcheckedβ attribute indicated by @NIVED_NAMBIAR for the first situation and your indication for the second issue.
Thanks a lot!
