第二个asp.net分页代码(用gridview控件分页，数据不用sqldatasource)

我的第二个asp.net分页，用gridview控件分页，实现简单，并且gridview的数据源是用sqldatasource链接的

前台代码：

<asp:GridView  ID="grd" runat="server" AllowPaging="true" PageSize="6"   AutoGenerateColumns="False" DataKeyNames="id"  Width="928px" 
                onpageindexchanging="grd_PageIndexChanging">
                <Columns>
                    <asp:BoundField DataField="用户名" HeaderText="用户名" ReadOnly="True" 
                        SortExpression="用户名" />
                    <asp:HyperLinkField DataNavigateUrlFields="id" DataNavigateUrlFormatString="details.aspx?id={0}" DataTextField="标题" HeaderText="标题" />
                    <asp:BoundField DataField="内容" HeaderText="内容" SortExpression="内容" />
                    <asp:BoundField DataField="发帖时间" HeaderText="发帖时间" SortExpression="发帖时间" />
                    <asp:BoundField DataField="回复量" HeaderText="回复量" SortExpression="回复量" />
                    <asp:BoundField DataField="浏览量" HeaderText="浏览量" SortExpression="浏览量" />
                    <asp:BoundField DataField="最后一次访问时间" HeaderText="最后一次访问时间" 
                        SortExpression="最后一次访问时间" />
                </Columns>
            </asp:GridView>

 

注意AllowPaging为true表示允许分页,pagesize设置一页显示的行数。要实现分页功能还得实现onpageindexchanging事件。因此后台代码为：

protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            bind();
        }
    }
    public void bind()//将数据库中的内容填充到gridview中
    {
        SqlConnection conn = new SqlConnection(CommonMethods.connstring);
        conn.Open();
        string cmd = "select * from title";
        SqlDataAdapter da = new SqlDataAdapter(cmd, conn);
        DataSet ds = new DataSet();
        da.Fill(ds);
        grd.DataSource = ds;
        grd.DataBind();
        conn.Close();
    }
protected void grd_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        grd.PageIndex = e.NewPageIndex;
        bind();
    }
