AspNetPager实现 DataList分页

前台页面：

<form id="form1" runat="server">

    <div>   
    <center>
    <asp:DataList ID="DataListProductBind" runat="server" RepeatColumns="10"
        RepeatDirection="Horizontal" Width="1024px">
            <ItemTemplate>
                <asp:Image ID="Image1" runat="server" ImageUrl='<%#Eval("Pic_Url") %>' />
                <asp:Label ID="Label1" runat="server"  Font-Bold="true" Text='<%#Eval("Dev_ATMCode") %>' Width="120px"></asp:Label>
            </ItemTemplate>
    </asp:DataList>
        <webdiyer:AspNetPager ID="AspNetPager1" runat="server" PageSize="40"
            HorizontalAlign="Center" OnPageChanged="AspNetPager1_PageChanged"
            NumericButtonCount="4">
    </webdiyer:AspNetPager>
    </center>
    </div>

    </form>

后台：

        private void DataBinding(DataTable dtValue)
        {            
            PagedDataSource pds = new PagedDataSource();
            pds.DataSource = dtValue.DefaultView;
            AspNetPager1.RecordCount = dtValue.DefaultView.Count;
            pds.AllowPaging = true;
            pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1;
            pds.PageSize = AspNetPager1.PageSize;
            this.DataListProductBind.DataSource = pds;                        
            this.DataListProductBind.DataBind();
        }
