在ASP.Net中进行调查

Question

我正在尝试在ASP.Net项目中创建调查。 我的调查基于JSON模型。这是我的模特：

        public class Test
        {
            public string testName { get; set; }
            public List<ScoreSubject> scoreSubjects { get; set; }
            public List<Block> blocks { get; set; }
        }

        public class Block
        {
            public string blockName { get; set; }
            public string bodyTitle { get; set; }
            public string bodyText { get; set; }
            public string concludingText { get; set; }
            public List<Question> questions { get; set; }
        }

        public class Question
        {
            public int questionId { get; set; }
            public bool required { get; set; }
            public string questionTextAboveAnswers { get; set; }
            public string questionTextBelowAnswers { get; set; }
            public string warningText { get; set; }
            public string scoreSubject { get; set; }
            public List<Answer> answers { get; set; }
        }


        public class Answer
        {
            public int answerId { get; set; }
            public string answerText { get; set; }
            public int score { get; set; }
            public string warningText { get; set; }
            public int skipQuestions { get; set; }
        }

我有3个街区，每个都有一些问题。我试图做的是在小组中显示答案。单击按钮：呈现下一个问题。

这是我的usercontrol的一部分：

public List<RootNode> rootNode;

        int _CounterBlock;
        int _CounterQuestions;

        protected void Page_Load(object sender, EventArgs e)
        {
            if(!Page.IsPostBack)
            { 
                _CounterBlock = 0;
                _CounterQuestions = 0;
            }


            LoadJson(); //Convert JSON data to models
            SetControls();
            populateDataByIndex();

        }

        private void SetControls()
        {
            testPanel.Visible = true;
            ProceedLanguageButton.Visible = true;
            QuestionsLanguageRadioButtonList.Visible = false;

        }

        public void populateDataByIndex()
        {

            Rootnode list = rootNode.First(); //Always 1st item in array

            //Get block by index
            Block block = list.test.blocks[_CounterBlock];

            //Load next block when there are no answers, or last answer is filled
            if((_CounterQuestions >= block.questions.Count) || block.questions.Count < 0)
            {
                _CounterBlock++;
                _CounterQuestions = 0;
            }


            bodyTitle.Text = block.bodyTitle;
            bodyText.Text = block.bodyText;

            if(block.questions.Count > 0)
            {
                //Show list when questions is not null
                QuestionsLanguageRadioButtonList.Visible = true;

                //Remove existing items from list
                QuestionsLanguageRadioButtonList.Items.Clear();

                //Show label and question
                Question question = block.questions[_CounterQuestions];
                questionLabel.Text = question.questionTextAboveAnswers;

                foreach(var answer in question.answers)
                {
                    QuestionsLanguageRadioButtonList.Items.Add(new ListItem() { Text = answer.answerText, Value = answer.score.ToString() });
                }
            }
        }

但是，这总是显示我的第一个块。我怎样才能在这里实现“分页”？我尝试使用Session，但这在usercontrol中不可用。

这是我的小组：

<asp:Panel runat="server" ID="TestPanel" DefaultButton="ProceedLanguageButton">

    <div>
        <h1><asp:Label runat="server" ID="bodyTitle"></asp:Label></h1>
    </div>

    <div>
        <asp:Label runat="server" id="bodyText"></asp:Label>
    </div>

    <div>
        <asp:Label runat="server" ID="questionLabel"></asp:Label>
    </div>
    <div>
        <cc1:languageradiobuttonlist id="QuestionsLanguageRadioButtonList" runat="server" repeatdirection="Vertical" basekey="Questions" />
    </div>

    <div>
        <asp:Label runat="server" id="concludingText"></asp:Label>
    </div>
</asp:Panel>


<div class="contentSeperator"></div>

<%--BUTTONS--%>
<div>
    <cc1:LanguageButton runat="server" ID="ReturnLanguageButton" CssClass="defaultButton Actie"
        CausesValidation="false" OnClick="ReturnLanguageButton_Click" Key="Test:Return" />
    <cc1:LanguageButton runat="server" ID="ProceedLanguageButton" CssClass="defaultButton Proceed"
        CausesValidation="false" OnClick="ProceedLanguageButton_Click" Key="Test:Proceed" />
</div>

注意：这不是MVC项目。

有人能指出我正确的方向吗？提前谢谢。
