Question

enter image description here 嗨，大家好，

我正在研究一个简单的调查应用程序。我面临着从现有的数据库问题类别中动态生成调查表的挑战。

基本上，我在3个主要问题类别中有问题，第一类有2个问题，第二类有3个问题，第3个也有3个问题......从3个主要问题类别中提出8个问题。

当我想实现它时，想到了gridView，最终我用它来生成表单接口。挑战在于，我无法按照我需要的方式格式化生成的界面。生成的表单界面的图像也可以在这里访问： http://brandberries.com.ng/interface.html

这是codeBehind：

public partial class Survey : System.Web.UI.Page
{
    string responder = WindowsIdentity.GetCurrent().Name.ToString();
    int catID;
    int qID;
    int canteenID;
    string response;
    string comments;
    string comment;
    string responseDate = DateTime.Now.ToShortDateString().ToString();

    SqlDataSource sds1 = new SqlDataSource();

    protected void Page_Init(object sender, EventArgs e)
    {
        // set dataSource properties
        sds1.ConnectionString = "Data Source=BNY-D-1245;Initial Catalog=canteenSurvey;Integrated Security=True";
        sds1.ProviderName = "System.Data.SqlClient";


        // bind datasource to page
        sds1.DataBind();
        //sds2.DataBind();
    }
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void gvCategory_PreRender(object sender, EventArgs e)
    {
        foreach (GridViewRow item in gvCategory.Rows)
        {
            catID = (int)gvCategory.DataKeys[item.RowIndex].Value;

            GridView gvQuestion = (GridView)item.FindControl("gvQuestion");

            sds1.SelectCommand = "SELECT * FROM tblQuestion WHERE [CatID] = " + catID;

            gvQuestion.Columns[0].Visible = true;            
            gvQuestion.DataSource = sds1;
            gvQuestion.DataBind();
            gvQuestion.Columns[0].Visible = false;

            foreach (GridViewRow row in gvQuestion.Rows)
            {
                qID = (int)gvQuestion.DataKeys[row.RowIndex].Value;
            }

        }

    }

    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow masterItem in gvCategory.Rows)
        {
            catID = (int)gvCategory.DataKeys[masterItem.RowIndex].Value;

            GridView gvQuestion = (GridView)masterItem.FindControl("gvQuestion");

            foreach (GridViewRow masterRow in gvQuestion.Rows)
            {
                qID = (int)gvQuestion.DataKeys[masterRow.RowIndex].Value;

                GridView gvCanteen = (GridView)masterRow.FindControl("gvCanteen");

                foreach (GridViewRow masterData in gvCanteen.Rows)
                {
                    canteenID = (int)gvCanteen.DataKeys[masterData.RowIndex].Value;
                    response = ((DropDownList)masterData.FindControl("ddlResponse")).SelectedValue;
                    //TextBox userComment = gvCanteen.FindControl("txtComment") as TextBox;
                    //comment = userComment.Text;
                }
            }
        }

        comments = txtComments.Text;
        // Insert into the database

        string constr = "Data Source=BNY-D-1245;Initial Catalog=canteenSurvey;Integrated Security=True";

        // SQL Query to insert values into the database

        string sqlQuery = "INSERT INTO tblFeedBack (catID, qID, canteenID, response, responder, responseDate)";
        sqlQuery += "VALUES (@catID, @qID, @canteenID, @response, @responder, @responseDate )";

        //string sqlQuery2 = "INSERT INTO tblComments (responder, comments) VALUES (@responder, @comments)";

        //SqlCommand query = new SqlCommand();
        using (SqlConnection dataConnection = new SqlConnection(constr))
        {
            using (SqlCommand dataCommand = dataConnection.CreateCommand())
            {
                dataConnection.Open();
                dataCommand.CommandType = CommandType.Text;
                dataCommand.CommandText = sqlQuery;
                dataCommand.Parameters.AddWithValue("@catID", catID);
                dataCommand.Parameters.AddWithValue("@qID", qID);
                dataCommand.Parameters.AddWithValue("@canteenID", canteenID);
                dataCommand.Parameters.AddWithValue("@response", response);
                dataCommand.Parameters.AddWithValue("@responder", responder);
                dataCommand.Parameters.AddWithValue("@responseDate", responseDate);

                dataCommand.ExecuteNonQuery();
                dataConnection.Close();
            }

        }

    }
}

以下是调查界面的aspx文件：

        </table>

        <asp:SqlDataSource ID="CategorySDS" runat="server"

    <div>

            onclick="btnSubmit_Click" />
    </div>
    </form>
    </asp:Content>

无论如何，我可以格式化gridview生成的代码，使其看起来像附加的那样更有条理吗？
