Remarks from MSDN for RadioButttonList SelectedValue

This property returns the Value property of the selected ListItem. The SelectedValue property is commonly used to determine the value of the selected item in the list control. If multiple items are selected, the value of the selected item with the lowest index is returned. If no item is selected, an empty string ("") is returned.

So suggest #1 is that you atleast make on the item as default selection by using the attribute Selected="true"

Suggestion #2 will be (just a opinion) for the sake of readability use SelectedItem.Value

protected void btnCalculate_Click(object sender, EventArgs e)
{
    string selectedValue = RadioButtonList1.SelectedItem.Value;
}

When you bind your RadioButtonList, you can place your code in ! IsPostback , in order to don't erase your `selected value, when you post your control (click event).

Page_Load :

if(! isPostBack)
{
   //Bind your radioButtonList

}`

Nota : You persist your datas with ViewState

Or You could use :--

string selectedValue = RadioButtonList1.SelectedValue.ToString();
