我做了一个asp.net的页面C#写的，页面里有两个div 一个是<div id="doctorId" runat="server"></div> 另一个是 <div id="weekScheduler_dayRow" runat="server"></div>。
然后在后台cs里面，doctorId.Controls.Clear();weekScheduler_dayRow.Controls.Clear();
然后根据一个已经存放好数据的SortedList<DateTime, List<tableDoc>> totallist = new SortedList<DateTime, List<tableDoc>>();进行赋值。
for (int i = 0; i < totallist.Count; i++)
  {
  HtmlGenericControl div_doc = getDiv(null, "", "10", null);
  for (int j = 0; j < totallist.Values[i].Count; j++)
  {
   
  int id = int.Parse(totallist.Values[i][j].Id);
  HtmlGenericControl hdiv = getDivHour(j.ToString() + id.ToString(), id.ToString(), "", null, false);
  div_doc.Controls.Add(hdiv);

  } doctorId.Controls.Add(div_doc);
//以上是第一个div的赋值，以下是第二个div的赋值
  int dcount = totallist.Values[i].Count;
  listCapacity = listCapacity + dcount;
  HtmlGenericControl div_day = getDiv(null, "days", (divWidth * dcount).ToString(), null);
  HtmlGenericControl div_weekday;
  if (doctor_count == 1)
  {
  div_weekday = getDiv(totallist.Keys[i].ToString("M月d日 (ddd)"), "weekDay", (divWidth - 1).ToString(), (headerHeight * 2).ToString());
   
  }
  else
  {
  if (dcount == 1)
  {
  div_weekday = getDiv(totallist.Keys[i].ToString("M\\/d(ddd)"), "weekDay", (divWidth * dcount - 1).ToString(), null);
  }
  else
  {
  div_weekday = getDiv(totallist.Keys[i].ToString("M月d日(ddd)"), "weekDay", (divWidth * dcount - 1).ToString(), null);
  }
  }
  div_weekday.ID = "day_" + listCapacity +"_" + totallist.Keys[i].ToString("yyyy-M-d");
  div_day.Controls.Add(div_weekday);
  if (doctor_count > 1)
  {
  //int qcount = queryEmp.Count();
  int cc = 1;
  foreach (var d in totallist.Values[i])
  {
  string name = string.Empty;
  if (d.Value == 1)
  {
  name =js1+d.Id+js2+ d.Text+js3;
  }
  else
  {
  name =js1+d.Id+ js2+ d.Name+js3;
  }
  HtmlGenericControl div_doctor = getDiv(name, "doctor", (divWidth - 1).ToString(), null);
  if (cc == dcount)
  {
  div_doctor.Style.Add("border-right", "1px solid #00008B");
  }
  div_day.Controls.Add(div_doctor);
  cc++;
  }
  }
  weekScheduler_dayRow.Controls.Add(div_day);
  }

问题是，我第一次载入页面时候，一切正常，然后我在页面上有一个链接，点击这个链接会发一个ajax请求再到这个页面，然后重新装载数据，这时候，我发现ajax请求重新刷页面的时候，第一个div仍然显示第一次刷新的数据，而第二个div显示再次装载的数据，这让我非常费解！甚至是百思不得其解！为什么呢？这是为什么呢？请哪位高手给答疑解惑~~ 鞠躬感谢！
