Your datagrid control's name is dgReports

You can assign it's datasource as below

        DataViewManager dsView;
        dgReports.DataSource = dsView;
        dgReports.DataMember = tablename;

you have to bind the Accordion control in the page_load event..
then only its temdatabound event will fire...

eg.
string Name = "Experts-exchange";
Accordion1.DataSource = Name;
Accordion1.DataBind();

You have to register the ItemDataBound event like this..
<ajaxToolkit:Accordion ID="acc1" runat="server" SelectedIndex="1" FadeTransitions="true" 
                                                FramesPerSecond="40" TransitionDuration="250" AutoSize="None" RequireOpenedPane="false" 
                                                HeaderCssClass="HeaderTab"   OnItemDataBound="acc1_ItemDataBound">

hi sijishJohn,

     I accomplished the task, by doing the code in snippet.
public void accordion()
    {
        DataSet dsDistibutors = Fund.GetAllDistibutor();
        AccordionPane ap1 = new AccordionPane();
        ap1.HeaderContainer.Controls.Add(new LiteralControl("Select Distributor"));
        ap1.ContentContainer.Controls.Add(GetRadioButtonList());
        Accordion1.Panes.Add(ap1);
    }
    private RadioButtonList GetRadioButtonList()
    {
        DataSet dsDistibutors = Fund.GetAllDistibutor();
        RadioButtonList RBList = new RadioButtonList();
        RBList.DataSource = dsDistibutors;
        RBList.DataTextField = "USER_NM";
        RBList.DataValueField = "USER_NM";
        RBList.DataBind();
        RBList.AutoPostBack = true;
        return RBList;
    }
