Implement SelectedIndexChanged event like this-

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)

{

//write your code here

}

Try this and let me know.

Hi,
you can use the below code
--------------------------------------------------------------------------------------
public RadioButtonList()
[ValidationPropertyAttribute("SelectedItem")]
public class RadioButtonList : ListControl,
IRepeatInfoUser, INamingContainer, IPostBackDataHandler
--------------------------------------------------------------------------------------

for details of the properties, methods, events etc. follow the below post
