I am having 2 radio buttons on my windows form (C#). when the user clicks on a radio button I want some code to run.

In which event of the radio button I should write the code?

I tried in Checkedchanged event of the radio button, whenever the user clicks on the other radio button, this event gets triggered. I want the code to be executed only when the user clicks on the radio button and not when the user checks another radio button.

thanks
