c# radiobuttonlist control

Question

I am relatively new to c# and the event handling concept.

Inside this function I need to get a reference to the RadioButtonList control that fired the event. Also, need to retrieve information from the selected radiobutton from the control

TIA

protected void Option_SelectedIndexChanged(object sender, EventArgs e)
    {
}

Answer 1

protected void Option_SelectedIndexChanged(object sender, EventArgs e)
{
    RadioButtonList sourceRadioButtonList = (RadioButtonList)sender;

    string selectedOption = sourceRadioButtonList.SelectedValue;
}
