[Solved] System.IndexOutOfRangeException: There is no row at position 0 in ASP.Net

I have 2 radio button list boxes, each radiolistbox has 3 radio text options to select, I will select 1 radio text for each. Next time, when i login again, (with session) it will show the selected radio text that I had selected yesterday.

When I try to run the codes as above it shown an error

System.IndexOutOfRangeException: 'There is no row at position 0.'

Do you have any idea to fix this?

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
    <br />
    <br />
    <br />
    Test 1
    <asp:RadioButtonList ID="RadioButtonList1" runat="server" RepeatLayout="Table" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">
         <asp:ListItem Text="*Answer 1*" Value="1" />
        <asp:ListItem Text="*Answer 2*" Value="2" />
        <asp:ListItem Text="*Answer 3*" Value="3" />
    </asp:RadioButtonList>
    <br />
    <br />
    <br />
    Test2
    <asp:RadioButtonList ID="RadioButtonList2" runat="server" RepeatLayout="Table">
        <asp:ListItem Text="*Answer 1*" Value="1" />
        <asp:ListItem Text="*Answer 2*" Value="2" />
        <asp:ListItem Text="*Answer 3*" Value="3" />        
    </asp:RadioButtonList>
    <asp:Button Text="NextPage" runat="server"  OnClick="NextPage"/>
