Hi Shrikanth,

What action have you configured on change event on the radio button?

Also could you confirm if you have this radio button configured in grid?

Could you please provide the screen-shot of the configuration.

Please check below link.

"onChange" action in Radio Button won't work inside a repeat grid. This is an expected behavior.
