hi

i need to develop an accordian control with dynamic paging in asp.net.
I saw sample code in this site and implemented it:
http://yasserzaid.wordpress.com/2009/02/23/paging-dynamic-ajax-acordion-control/[^]

I am getting the data and binding the data to the header.

But when i click on the header, the control is not expanding.

PagedDataSource pds = new PagedDataSource();
  public int CurrentPage
  {
      get
      {
          if (this.ViewState["CurrentPage"] == null)
          {
              return 0;
          }
          else
          {
              return Convert.ToInt16(this.ViewState["CurrentPage"].ToString());
          }
      }
      set
      {
          this.ViewState["CurrentPage"] = value;
      }
  }
  private void doPaging()
  {
      DataTable dt = new DataTable();
      dt.Columns.Add("PageIndex");
      dt.Columns.Add("PageText");
      for (int i = 0; i < pds.PageCount; i++)
      {
          DataRow dr = dt.NewRow();
          dr[0] = i;
          dr[1] = i + 1;
          dt.Rows.Add(dr);
      }
      dlPaging.DataSource = dt;
      dlPaging.DataBind();
  }
  public void getCategories()
  {
      MySqlConnection sqlConn = new MySqlConnection("server=183.82.96.20;database=grid;uid=root;Pwd=pwd;");
      sqlConn.Open();
      MySqlCommand sqlSelect = new MySqlCommand("SELECT * FROM registrations", sqlConn);
      sqlSelect.CommandType = System.Data.CommandType.Text;
      MySqlDataAdapter sqlAdapter = new MySqlDataAdapter(sqlSelect);
      DataTable dt = new DataTable();
      sqlAdapter.Fill(dt);
      pds.DataSource = dt.DefaultView;
      pds.AllowPaging = true;
      pds.PageSize = Convert.ToInt16(ddlPageSize.SelectedValue);
      pds.CurrentPageIndex = CurrentPage;
      lnkbtnNext.Enabled = !pds.IsLastPage;
      lnkbtnPrevious.Enabled = !pds.IsFirstPage;
      Accordion1.DataSource = pds;
      Accordion1.DataBind();
      doPaging();
  }
  protected void Page_Load(object sender, EventArgs e)
  {
      if (!IsPostBack)
      {
          getCategories();
      }
  }
  protected void Accordion1_ItemDataBound(object sender, AjaxControlToolkit.AccordionItemEventArgs e)
  {
      if (e.ItemType == AjaxControlToolkit.AccordionItemType.Content)
      {
          MySqlConnection sqlConn = new MySqlConnection("server=183.82.96.20;database=grid;uid=root;Pwd=daf");
          MySqlCommand sqlSelect = new MySqlCommand("SELECT * FROM registrations where id = '" + ((HiddenField)e.AccordionItem.FindControl("txt_categoryID")).Value + "'", sqlConn);
          sqlSelect.CommandType = System.Data.CommandType.Text;
          MySqlDataAdapter sqlAdapter = new MySqlDataAdapter(sqlSelect);
          DataSet myDataset = new DataSet();
          sqlAdapter.Fill(myDataset);

          GridView grd = new GridView();
          grd = (GridView)e.AccordionItem.FindControl("GridView1");
          grd.DataSource = myDataset;
          //GridView grd = new GridView();
          //grd = (GridView)e.AccordionItem.FindControl("GridView1");
          //grd.DataSource = myDataset;
          grd.DataBind();
      }
  }
  protected void dlPaging_ItemCommand(object source, DataListCommandEventArgs e)
  {
      if (e.CommandName.Equals("lnkbtnPaging"))
      {
          CurrentPage = Convert.ToInt16(e.CommandArgument.ToString());
          getCategories();
      }
  }
  protected void dlPaging_ItemDataBound(object sender, DataListItemEventArgs e)
  {
      LinkButton lnkbtnPage = (LinkButton)e.Item.FindControl("lnkbtnPaging");
      if (lnkbtnPage.CommandArgument.ToString() == CurrentPage.ToString())
      {
          lnkbtnPage.Enabled = false;
          lnkbtnPage.Font.Bold = true;
      }
  }
  protected void lnkbtnPrevious_Click(object sender, EventArgs e)
  {
      CurrentPage -= 1;
      getCategories();
  }
  protected void lnkbtnNext_Click(object sender, EventArgs e)
  {
      CurrentPage += 1;
      getCategories();
  }
  protected void ddlPageSize_SelectedIndexChanged(object sender, EventArgs e)
  {
      CurrentPage = 0;
      getCategories();
  }

please can any body tell me what's wrong here?
