ASP.NET（C＃）分页没有任何控制

Question

I am new and a novice to asp.net(C#). I know little about binding to GridView Control. But now I face some huge problems. Some of my data are repeated and I control them with code-behind. Put my code in variable, append to div, not in GridView. I also want paging for this.

Can anybody help? Ask me if you guys need something more specific. I am a beginner, so I don't know what code to provide.

Here's the overview:
Doctors have many appointed place
appointed places have several day
several days have several times-shift ...

public void BindList(int start, int pagesize)
{
    lblPageIndex.Text = page.ToString();
    roles = DoctorBLL.GetAllDoctor(page, recordPerPage);
    List<int> rIDs = ((from r in roles select r.doctorID).Distinct()).ToList();
    foreach(int rID in rIDs)
    {
        doctorList.InnerHtml += "<table width='100%' border=1 cellspacing=0 style='border-collapse:collapse;margin-top:10px;'><tr>";
        List<DoctorEntity> dlist = roles.Where(role => role.doctorID == rID).ToList();
        if (dlist.Count > 0)
        {
            doctorList.InnerHtml += "<td>";
            doctorList.InnerHtml += "<h2>" + dlist.First().title + "</h2>";
            doctorList.InnerHtml += "<h3>" + dlist.First().name + "</h3>";
            doctorList.InnerHtml += "</td>";
            doctorList.InnerHtml += "<td>";
            doctorList.InnerHtml += dlist.First().qualification;
            doctorList.InnerHtml += "</td>";
            doctorList.InnerHtml += "</tr>";
            doctorList.InnerHtml += "<tr>";
            doctorList.InnerHtml += "<td colspan='3'>";
        }
        List<int> dirIDS = ((from r in dlist select r.directoryID).Distinct()).ToList();

        foreach (int dirid in dirIDS)
        {
            doctorList.InnerHtml += "<ul style='width:200px;float:left;list-style:none;'>";
            List<DoctorEntity> dirlist = dlist.Where(dt => dt.directoryID == dirid).ToList();
            if (dirlist.Count > 0)
            {
                doctorList.InnerHtml += "   <li><h4>" + dlist.First().directoryName + "</h4></li>";
            }
            foreach (DoctorEntity dir in dirlist)
            {
                doctorList.InnerHtml += "<li>" + dir.dayStr + " ( " + dir.startTime + " : " + dir.endTime + " ) </li>";
            }

            doctorList.InnerHtml += "</ul>";
        }
        doctorList.InnerHtml += "</td>";
        doctorList.InnerHtml += "</tr>";
        doctorList.InnerHtml += "</table>";
    }
    foreach (DoctorEntity entity in roles)
    {
        recordCount = entity.recordCount;
        break;
    }
    int flag = recordCount % recordPerPage;
    if (flag != 0)
    {
        flag = (recordCount / recordPerPage) + 1;
    }
    else
    {
        flag = recordCount / recordPerPage;
    }

    lblTotalPage.Text = flag.ToString();
    lblTotal.Text = recordCount.ToString();

    doctorList.DataBind();
}
#endregion

You can use cursors and Request.QueryString to achieve paging without using ontrols.

Example : If your page url is something like http://localhost/MyApp/DoctorsList.aspx then when you want to see the next 10 records just change the url to http://localhost/MyApp/DoctorsList.aspx?page=2

in you code behind use int pageNumber = Convert.ToInt32(Request.QueryString["page"]) to get the requested page, then use a database cursor to fetch the particular records based on the pageNumber value and then rebuild the table with code provided in the question. In short what i am saying is that instead of getting all the list of doctors, get n number of doctors using a cursor, and then use the Request.QueryString to browse through the remaining list.

But as Hassan Mokdad said in his comment, it would be better if you try with the grid view
