終於獨立實現分頁啦

 

//前台代碼： //沒什麼好說的；<table>
            <tr>
                <td align="right" style="width: 480px">當前第
                    <asp:Label ID="LblNum" runat="server"></asp:Label>頁/共有
                    <asp:Label ID="LblPage" runat="server"></asp:Label>頁&nbsp;&nbsp;|&nbsp;
                    <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl="images/back.gif" ="ImageButton2_Click" />
                    <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="images/next.gif" ="ImageButton1_Click" /></td>
            </tr>
        </table>

//後台代碼：public partial class Newcenter_Notice_ManagementNotice : System.Web.UI.Page
{
    public static int PageIndex = 1;//調用了CuctSoft.SqlDbHelper 類中的方法：
    private CuctSoft.SqlDbHelper gxc = new CuctSoft.SqlDbHelper();
  
    protected void Page_Load(object sender, EventArgs e)
    {
        datalistbing(PageIndex, 10);//刪除功能：
        if (Request.QueryString["action"] == "del")
        {
            gxc.dbExecuteSql("delete from Notice where NoticeID=" + Request.QueryString["id"] + "");
            datalistbing(PageIndex, 10);
        }    }//定義圖片按鈕適時顯現：    public void datalistbing(int PageIndex,int PageSize)
    {//調用了自己加的類——CuctSoft.Notice ：
        CuctSoft.Notice gxc = new CuctSoft.Notice();
        DataList1.DataSource = gxc.ShowPage(PageIndex, 10);
        DataList1.DataBind();
        int PageS = gxc.ShowPageCount();
        if (PageS > PageIndex) { ImageButton1.Visible = true; } else { ImageButton1.Visible = false; }
        if (PageIndex > 1) { ImageButton2.Visible = true; } else { ImageButton2.Visible = false; }
        LblNum.Text = Convert.ToString(PageIndex);
        LblPage.Text = Convert.ToString(PageS);
    }//分頁的圖片按鈕：
    protected void ImageButton2_Click(object sender, ImageClickEventArgs e)
    {
        PageIndex = PageIndex - 1;
        datalistbing(PageIndex, 10);
    }
    protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
    {
        PageIndex = PageIndex + 1;
        datalistbing(PageIndex, 10);
    }
}
