Populating Listview with Questions to answer(DropdownList and Textbox) depending on user information (ASP.NET)

Question

So I´m trying to create a registration page for a website where the User can register a number questions and answers. Users´ information is already on the app´s database (The number of questions the user needs to answer to register). So for example I have two users user1 and user2 each with 2 and 3 questions to register respectively. The questions are can be chosen from a dropdown list and below it there is a textbox to answer it.

So my question is, how do I populate the page for each respective user? user1 should have 2 DDLs and textboxes and user2 3 DDLs and textboxes. The reason for this is that users belong to different groups and thus have different requirements to register. I have seen from this page and this page that I may have to write my own engine?

Here is my aspx code:

<asp:ListView runat="server" ID="RegisterListView" DataKeyNames="Id" Visible="true"  >
            <LayoutTemplate>
                <table id="tblRegister"
                    style="width: 460px; background-color: lightgray" border="1">
                    <tr runat="server" id="itemPlaceholder">
                    </tr>
                </table>

            </LayoutTemplate>
            <ItemTemplate>
                <tr runat="server">
                    <td colspan="2">
                        <asp:DropDownList ID="RegisterQuestionList" runat="server" SelectMethod="RegisterQuestionList_GetData" />
                    </td>
                </tr>
                <tr runat="server">
                    <td colspan="2">
                        <asp:TextBox runat="server" />
                    </td>
                </tr>
            </ItemTemplate>
        </asp:ListView>

And here is my behind-code, which on pageload retrieves the user specific number of questions and the GetData method populates the drop down lists:

protected void Page_Load(object sender, EventArgs e)
    {
        using (var db = new AppContext())
        {

            var userID = Convert.ToInt32(Request.QueryString["User"]);
            userID = 9;
            var currentUser = db.Users.Find(userID);
            numQuestions = currentUser.NumQuestionsRegister;

        }
    }


    public IQueryable<QuestionPool> RegisterQuestionList_GetData()
    {
        var db = new AppContext();
        var questions = db.QuestionsPool;

        return questions;
    }

Some advise on how to approach this would be greatly appriciated. Thank you.
