前期我们分别介绍了gridview怎么进行固定表多行数据显示，以及怎么设计花样表头。下面我们介绍怎么利用gridview进行分页显示的同时还可以进行排序显示。

绑定数据及分页DEMO

<span style="font-family:Microsoft YaHei;font-size:18px;">public partial class GridviewPage : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        if (!IsPostBack)        {            ViewState["SortOrder"] = "EmpID";            ViewState["OrderDire"] = "ASC";            bind();        }    }    /// <summary>    /// 绑定数据    /// </summary>    public void bind()    {        string sqlStr = "select * from Employee";        DataView myds = Common.dataView(sqlStr);        string sort = (string)ViewState["SortOrder"] + " " + (string)ViewState["OrderDire"];        myds.Sort = sort;        GridView1.DataSource = myds;        GridView1.DataKeyNames = new string[] { "ID" };        GridView1.DataBind();        this.ddlCurrentPage.Items.Clear();        for (int i = 1; i <= this.GridView1.PageCount; i++)        {            this.ddlCurrentPage.Items.Add(i.ToString());        }        this.ddlCurrentPage.SelectedIndex = this.GridView1.PageIndex;    }    /// <summary>    /// 在 GridView 控件中的某个行被绑定到一个数据记录时发生。此事件通常用于在某个行被绑定到数据时修改该行的内容。    /// </summary>    /// <param name="sender"></param>    /// <param name="e"></param>    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)    {        this.lblCurrentPage.Text = string.Format("当前第{0}页/总共{1}页", this.GridView1.PageIndex + 1, this.GridView1.PageCount);         //遍历所有行设置边框样式        foreach (TableCell tc in e.Row.Cells)        {            tc.Attributes["style"] = "border-color:Black";        }        //用索引来取得编号        if (e.Row.RowIndex != -1)        {            int id = GridView1.PageIndex * GridView1.PageSize + e.Row.RowIndex + 1;            e.Row.Cells[0].Text = id.ToString();        }            }    /// <summary>    /// 重新绑定    /// </summary>    /// <param name="sender"></param>    /// <param name="e"></param>    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)    {        //下拉选框值与当前页值一致        this.GridView1.PageIndex = this.ddlCurrentPage.SelectedIndex;        bind();    }    protected void lnkbtnFrist_Click(object sender, EventArgs e)    {        //第一页，当前索引为0        this.GridView1.PageIndex = 0;        bind();    }    protected void lnkbtnPre_Click(object sender, EventArgs e)    {        if (this.GridView1.PageIndex > 0)        {            //前一页，当前索引减一            this.GridView1.PageIndex = this.GridView1.PageIndex - 1;            bind();        }    }    protected void lnkbtnNext_Click(object sender, EventArgs e)    {        if (this.GridView1.PageIndex < this.GridView1.PageCount)        {            //下一页，当前页索引值加一            this.GridView1.PageIndex = this.GridView1.PageIndex + 1;            bind();        }    }    protected void lnkbtnLast_Click(object sender, EventArgs e)    {        //最后一页，将总页数赋给当前索引        this.GridView1.PageIndex = this.GridView1.PageCount;        bind();    }</span>

排序显示DEMO

<span style="font-family:Microsoft YaHei;font-size:18px;">    /// <summary>    /// 在单击某个用于对列进行排序的超链接时发生，但在 GridView 控件执行排序操作之前。此事件通常用于取消排序操作或执行自定义的排序例程。    /// </summary>    /// <param name="sender"></param>    /// <param name="e"></param>    protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)    {        //sortexpression为排序表达式（账号、姓名、地址等等）        string sPage = e.SortExpression;        if (ViewState["SortOrder"].ToString() == sPage)        {            //判断当前状态为升序还是降序；            if (ViewState["OrderDire"].ToString() == "DESC")                ViewState["OrderDire"] = "ASC";            else                ViewState["OrderDire"] = "DESC";        }        else        {            ViewState["SortOrder"] = e.SortExpression;        }        bind();    }</span>
