Hi Radio_Button.Changed is quite confusing and needs to replaced with Radio_Button.Clicked so that we can change radio button status when one of the radio buttons is clicked.
Like in below block it will not work (to make it work I have to click twice):
I think radio button had a Clicked event handler but was replaced in one of previous releases.
Thank you @Boban and @Ken for your replies as well as solutions.
Instead of using complicated blocks ‘click’ event will be more flexible and easy to use and understand for everyone.
