DataList的使用+分页 (转)

datalist和repeater一样，都是根据自己的需要添加自己的模板，简单例子如下：

前台代码如下：

<body>
    <form id="form1" runat="server">
    <div>
        <asp:DataList ID="DataList1" runat="server" DataKeyField="ID"  RepeatDirection="Horizontal">
            <ItemTemplate>
                <div style="text-align: left; background-color: #99ffcc;">
                    ID:<asp:Label ID="IDLabel" runat="server" Text='<%# Eval("ID") %>'></asp:Label><br />
                    Name:<asp:Label ID="Pro_NameLabel" runat="server" Text='<%# Eval("Name") %>'></asp:Label><br />
                    Price:<asp:Label ID="Pro_PriceLabel" runat="server" Text='<%# Eval("Price") %>'></asp:Label><br />
                    Introduce:<asp:Label ID="Pro_IntroduceLabel" runat="server" Text='<%# Eval("Introduce") %>'></asp:Label><br />
                </div>                           
            </ItemTemplate>
        </asp:DataList>
        当前页：<asp:Label ID="lblCurrent" runat="server" Text="1"></asp:Label>
        总页数：<asp:Label ID="lblTotal" runat="server" Text="Label"></asp:Label>
        <asp:LinkButton ID="lbtnFirst" runat="server" OnClick="lbtnFirst_Click">第一页</asp:LinkButton>
        <asp:LinkButton ID="lbntUp" runat="server" OnClick="lbntUp_Click">上一页</asp:LinkButton>
        <asp:LinkButton ID="lbtnDown" runat="server" OnClick="lbtnDown_Click">下一页</asp:LinkButton>
        <asp:LinkButton ID="lbtnLast" runat="server" OnClick="lbtnLast_Click">最后一页</asp:LinkButton>
    </div>
    </form>
</body>

后台代码如下：

protected void Page_Load(object sender, EventArgs e)
{
    DataListBind();
}
 
private void DataListBind()
{
    int current_page = Convert.ToInt32(lblCurrent.Text);
    SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
    SqlDataAdapter oda = new SqlDataAdapter("select * from June_Pro", con);
    DataSet ds = new DataSet();
    oda.Fill(ds);
 
    PagedDataSource ps = new PagedDataSource();
    ps.DataSource = ds.Tables[0].DefaultView;
    ps.AllowPaging = true;
    ps.PageSize = 4;
    lblTotal.Text = ps.PageCount.ToString();
    ps.CurrentPageIndex = current_page - 1;
    lbtnFirst.Enabled = true;
    lbntUp.Enabled = true;
    lbtnDown.Enabled = true;
    lbtnLast.Enabled = true;
    if (current_page == 1)
    {
        lbtnFirst.Enabled = false;
        lbntUp.Enabled = false;
    }
    if (current_page == Convert.ToInt32(lblTotal.Text))
    {
        lbtnLast.Enabled = false;
        lbtnDown.Enabled = false;
    }
    DataList1.DataSource = ps;
    DataList1.DataBind();
}
protected void lbtnFirst_Click(object sender, EventArgs e)
{
    lblCurrent.Text = "1";
    DataListBind();
}
protected void lbtnDown_Click(object sender, EventArgs e)
{
    lblCurrent.Text = (Convert.ToInt32(lblCurrent.Text) + 1).ToString();
    DataListBind();
}
protected void lbntUp_Click(object sender, EventArgs e)
{
    lblCurrent.Text = (Convert.ToInt32(lblCurrent.Text) - 1).ToString();
    DataListBind();
}
protected void lbtnLast_Click(object sender, EventArgs e)
{
    lblCurrent.Text = lblTotal.Text;
    DataListBind();
}

运行结果如下图：
