<itemtemplate>

<asp:Label ID="QuestiontextLabel" runat="server"
Text='<%# Eval("Questiontext") %>' />
<br />

<asp:Label ID="Label1" runat="server"
Text='<%# Eval("QuestionID") %>' Visible="false" />
<br />
<asp:Label ID="Label3" runat="server"
Text='<%# Eval("Answertype") %>' />
<br />
<asp:RadioButtonList ID="RadioButtonList1" runat="server"
DataSourceID="SqlDataSource1" DataTextField="Choicetext"
