自己做一个可以翻页的列表，里面包含了图片和文字，就是类似如此效果：

代码如下：
<x

ageManager ID="

ageManager1" runat="server" EnableAjax="true" AutoSizePanelID="sf_Main"/>
<x:SimpleForm ID="sf_Main" runat="server" ShowBorder="false" BodyPadding="20px"
            LabelWidth="10px" EnableBackgroundColor="true" ShowHeader="false" AutoScroll="true">
            <Toolbars>
            <x:Toolbar ID="Toolbar1" runat="server">
            <Items>

               <x:TextBox ID="txt_NameOrIdNumber" runat="server" EmptyText="请输入学生姓名或身份证号" />
               <x:SimpleForm ID="SimpleForm1" runat="server" ShowBorder="false" BodyPadding="0px,10px"
            EnableBackgroundColor="true" ShowHeader="false" LabelWidth="30px">
            <Items>
               <x

ropDownList ID="ddl_FullClassName" runat="server" Label="班级" OnSelectedIndexChanged="ddl_FullClassName_SelectedIndexChanged" AutoPostBack="true"/>
            </Items>
               </x:SimpleForm>
               <x:Button ID="btn_Import" Icon="DiskUpload" runat="server" Text="导入" />
               <x:ToolbarFill ID="tbf_t" runat="server"></x:ToolbarFill>
               <x:Button ID="btn_First" Icon="ResultsetFirst" runat="server" ToolTip="第一页"/>
               <x:Button ID="btn_Previous" Icon="ResultsetPrevious" runat="server" ToolTip="上一页"/>
               <x:ToolbarSeparator ID="tbs_t_1" runat="server" />
               <x

abel ID="lblTips" runat="server" Text="转到" />
<x:TextBox ID="txt_CurrentPage" runat="server" Width="60px" Text="1" AutoPostBack="true"/>
<x

abel ID="lbl_TotalPage" runat="server" Text="共1页"/>
               <x:ToolbarSeparator ID="tbs_t_2" runat="server" />
               <x:Button ID="btn_Next" runat="server" Icon="ResultsetNext" ToolTip="下一页"/>
               <x:Button ID="btn_Last" runat="server" Icon="ResultsetLast"  ToolTip="最后一页"/>
            </Items>
            </x:Toolbar>
            </Toolbars>
            <Items>
      <x:ContentPanel ID="frm_Main" EnableBackgroundColor="true" ShowBorder="true" ShowHeader="false" runat="server" BodyPadding="0px" AutoScroll="true">

      <table id="tb_Main" runat="server" cellspacing="0" cellpadding="0" style="text-align:center;"></table>
      </x:ContentPanel>

      </Items>
      </x:SimpleForm>

  private void Init_PhotoList(int currentPage)
      {

         this.Operation.PageSize = 45;
         this.Operation.PageIndex = currentPage;
         IList<StudentD> studentList = this.Operation.GetIList;
         double pageCount = Math.Ceiling((double)studentList.Count /45);
         this.lbl_TotalPage.SetValue(string.Format("共{0}页", pageCount));
         double rowCount = Math.Ceiling((double)studentList.Count / 9);
         for (int rowIndex = 0; rowIndex < rowCount; rowIndex++)
         {
            HtmlTableRow row = new HtmlTableRow();
            for (int columnIndex = 0; columnIndex < 9; columnIndex++)
            {
                  int index = rowIndex*9+columnIndex;
                  if (index >= studentList.Count)
                  {
                     break;
                  }
                  HtmlTable table = new HtmlTable();
                  table.Align = "Center";
                  HtmlTableRow row_Photo = new HtmlTableRow();
                  HtmlTableRow row_Name = new HtmlTableRow();
                  string fullClassName = studentList[index].FullClassName.Trim();
                  string className = studentList[index].ClassName.Trim();
                  FineUI.Label lblIDNumber = new FineUI.Label();
                  lblIDNumber.Text = studentList[index].IDNumber.Trim();
                  FineUI.LinkButton lbName = new FineUI.LinkButton();
                  lbName.Text = studentList[index].StudentName.Trim();
                  FineUI.Image imgIDphoto = new FineUI.Image();
                  string fileName = "~/Photo/HeadPhoto/Thumbnail/" + className + "_" + lbName.Text + lblIDNumber.GetValue() + ".jpg";
                  if (File.Exists(Server.MapPath(fileName)))
                  {
                     imgIDphoto.ImageUrl = fileName;
                  }
                  else
                  {
                     imgIDphoto.ImageUrl = "~/Images/HeadPhoto.png";
                  }


                  HtmlTableCell cell_Photo = new HtmlTableCell();
                  cell_Photo.Width = "150";
                  cell_Photo.Controls.Add(imgIDphoto);
                  row_Photo.Cells.Add(cell_Photo);
                  HtmlTableCell cell_Name = new HtmlTableCell();
                  cell_Name.Controls.Add(lbName);
                  cell_Name.Width = "150";
                  row_Name.Cells.Add(cell_Name);
                  table.Rows.Add(row_Photo);
                  table.Rows.Add(row_Name);
                  HtmlTableCell cell = new HtmlTableCell();
                  cell.Controls.Add(table);
                  row.Cells.Add(cell);
            }
            tb_Main.Rows.Add(row);

         }
      }
//根据班级名称筛选
protected void ddl_FullClassName_SelectedIndexChanged(object sender, EventArgs e)
      {
         if (!this.ddl_FullClassName.GetValue().Equals(DString.RECORD_ALL))
         {
            this.Operation.AddEq(DColumn.FullClassNameD, this.ddl_FullClassName.GetValue());
         }
         this.pageCount = this.Operation.GetIList.Count;
         this.lbl_TotalPage.SetValue(string.Format("共{0}页", this.pageCount));
         this.txt_CurrentPage.SetValue("1");
         this.tb_Main.Rows.Clear();
         Init_PhotoList(0);

      }
可是发现无法更新 tb_Main里的内容，要显示的内容数据时正确的，就是不能显示在界面上，界面上的内容仍然是旧的，刚才看了几个相关的帖子，也没有找到解决办法，sanshi大哥说看官方例子，可是那个例子是讲Label内容的更新，而我这个是整个Table内容的更新，不知道哪位大师有没有解决的办法？谢谢！
