如何在Repeater中显示x项，并使用asp.net滚动或淡出下一个项

我有一个在从数据库显示的主页上显示'新闻'的中继器。我想一次只显示2条记录，并在滚动或淡出效果的某些毫秒后自动滚动下两个项目。

<asp:Repeater ID="RepDetails" runat="server" OnItemDataBound="RepDetails_ItemDataBound">
        <HeaderTemplate>
        </HeaderTemplate>
        <ItemTemplate>
            <div id="MainContent" style="border: 1px;">
                <table>
                    <tr>
                        <td rowspan="2" class="auto-style2">
                            <img src="Images/lasts1.png" />
                        </td>
                        <td>
                            <asp:Label ID="lblNewsTitle" runat="server" Font-Bold="True" /></td>
                        <td>&nbsp;</td>
                    </tr>
                    <tr width="100px">
                        <td>
                            <asp:Label ID="lblNewsDescription" runat="server" /></td>
                        <td>&nbsp;</td>
                    </tr>
                </table>
            </div>
            <hr />
        </ItemTemplate>
        <FooterTemplate>
        </FooterTemplate>
    </asp:Repeater>

.cs Page:

protected void RepDetails_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                DataRowView dr = e.Item.DataItem as DataRowView;
                string Id = Convert.ToString(dr["NewsID"]);
                //HtmlGenericControl teammemberapp = e.Item.FindControl("teammemberapp") as HtmlGenericControl;
                //Link to TeamMemberDetails Page 
                //teammemberapp.Attributes.Add("onclick", "window.location.href='NewsDetails.aspx?Id=" + Id + "'");
                string newsTitle = Convert.ToString(dr["NewsTitle"]);
                Label lblNewsDescription = e.Item.FindControl("lblNewsDescription") as Label;
                Label lblNewsTitle = e.Item.FindControl("lblNewsTitle") as Label;
                //set First Name Label
                lblNewsTitle.Text = newsTitle;
                string newsDescription = Convert.ToString(dr["NewsDescription"]);
                if (newsDescription.Length > 50)
                {
                    lblNewsDescription.Text = newsDescription.Substring(0, 50) + "..";
                }
                else
                {
                    lblNewsDescription.Text = newsDescription;
                }

            }
        }

    public void GetRecord()
            {
                string connectionString = ConfigurationManager.ConnectionStrings["DatabaseConnectionString"].ConnectionString.ToString();
                DataTable datatable = new DataTable();
                using (SqlConnection connection = new SqlConnection(connectionString))
                {
                    SqlCommand cmd = new SqlCommand();
                    cmd.Connection = connection;
                    connection.Open();
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.CommandText = "usp_NewsSelectYES";
                    SqlDataAdapter da = new SqlDataAdapter(cmd);
                    da.Fill(datatable);
                    connection.Close();
                }
                //Bind Table to Repeater
                RepDetails.DataSource = datatable;
                RepDetails.DataBind();
            }

    protected void Page_Load(object sender, EventArgs e)
            {
                if (!IsPostBack)
                {
                    //Get all news with yes
                    GetRecord();
                }
            }
