What I want is, to retrieve these data and display to the user as Question and Answer and enable the user to select with the Radio button. My problem is that how I can display this Question and Answer, whether I should use data bound controls like DataList, Repeater or Detail View with Radio Button inside the <Item Template> tag. And if it is so then how to maintain the state of the page (i.e. the value selected by the user) and compare the value selected by the user with the Correct Answer. I also want to have a button labeled ’Next’ so that when the User clicks on that button it should display the Next Question and Answer. I don’t know how to do that. If anybody knows Please help me with the code. I will be thankful if anybody helps me.

推荐答案

Replace your datalist with below designer code.

 <asp:DataList ID="DataList1" runat="server" CellPadding="4" ForeColor="#333333" OnItemDataBound="DataList1_ItemDataBound">
              <ItemTemplate>

                       <input id="rd" type="radio" name="rdGroup" value='<%# Eval("Chequedate") %>' ></input>
             </ItemTemplate>
  </asp:DataList>

Than you can get value of selected radio using Request.Form["rdGroup"] on click of a button.
