而且GridView会同时动态生成多个。如果是静态的话，用SqlDataSource很容易搞定，相信大家都会
就是让动态生成的GridView能够通过点击页码或上一页等按钮，能浏览动态生成的DataTable的数据
to cpp2017(慕白兄):thanks,用什么方法？能否写个实例代码？
是通过分页事件吗？GridView是动态生成的，如何写动态生成的GridView的分页事件？
GridView gv = new GridView();
        gv.PageIndexChanged += new EventHandler(gv_PageIndexChanged);
关注，现在我的gridview就是表头通过html生成的，数据源也不是预先绑定的，而是后台用select的  请问如何分页和排序，IndexChanged事件如何写呢？
to cpp2017(慕白兄):这样写不行，还要写gv_PageIndexChanged里面的实现代码，GridView是动态生成的，gv_PageIndexChanged里面的实现代码不好写，而且GridView会同时动态生成多个
protected void Page_Load(object sender, EventArgs e)
    {         DataTable dt = DataClass.ExecuteDataTable("select top 100 id,name from student");
        GridView gv = new GridView();
        gv.DataSource = dt.DefaultView;
        gv.AllowPaging = true;
        this.Panel1.Controls.Add(gv);

        gv.PageIndexChanging += new GridViewPageEventHandler(gv_PageIndexChanging);
        gv.DataBind();    }
  void gv_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView g = (GridView)sender;
        g.PageIndex = e.NewPageIndex;
        g.DataBind();
    }
编译出错，错误 57 “System.EventArgs”并不包含“NewPageIndex”的定义 C:\OfficeData\web\dt.aspx.cs 86 25 http://localhost/OfficeData/
应该是GridViewPageEventArgs e,请按上楼的写.
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)    {        if (GridView1.EditIndex != -1)        {            // Use the Cancel property to cancel the paging operation.            e.Cancel = true;            int newPageNumber = e.NewPageIndex + 1;        }        else        {            GridView1.PageIndex = e.NewPageIndex;            GridView1.DataBind();         }}然后把事件绑定到该控件上就行了。 <asp:GridView ID="GridView1",……onPageIndexChanging="GridView1_PageIndexChanging"……>
提示：错误 56 “dg_PageIndexChanging”的重载均与委托“System.EventHandler”不匹配 C:\OfficeData\web\dt.aspx.cs 67 40 http://localhost/OfficeData/
gv.PageIndexChanging += new GridViewPageEventHandler(gv_PageIndexChanging)
提示：未将对象引用设置到对象的实例。代码如下：
protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            for (int i = 0; i < 3; i++)
            {
                TabItem item1 = new Tab();
                item1.Text = "Tab " + i.ToString();
                TabStrip1.Items.Add(item1);
                PageView pv = new PageView();
                pv.ID = i.ToString();
                GridView dg = new GridView();
                DataTable table = new DataTable();                // Declare DataColumn and DataRow variables.
                DataColumn column;
                DataRow row;                // Create new DataColumn, set DataType, ColumnName
                // and add to DataTable.
                column = new DataColumn();
                column.DataType = System.Type.GetType("System.Int32");
                column.ColumnName = "id";
                table.Columns.Add(column);                // Create second column.
                column = new DataColumn();
                column.DataType = Type.GetType("System.String");
                column.ColumnName = "item";
                table.Columns.Add(column);                // Create new DataRow objects and add to DataTable.
                for (int j = 0; j < 10; j++)
                {
                    row = table.NewRow();
                    row["id"] = j;
                    row["item"] = "item " + j + i;
                    table.Rows.Add(row);
                }
               // SqlDataSource sd = new SqlDataSource();
                dg.DataSource = table.DefaultView;

                dg.PageSize = 3;
                dg.AllowPaging = true;                //dg.AllowSorting = true;

                dg.PageIndexChanging += new GridViewPageEventHandler(dg_PageIndexChanging);
                dg.DataBind();
                //dg.PageIndexChanged=

                pv.Controls.Add(dg);   //可以换成你自己的DataList
                MultiPage1.Controls.Add(pv);            }
        }

    }

    void dg_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView g = (GridView)sender;

        g.PageIndex = e.NewPageIndex;
        g.DataBind();        //dg_PageIndexChanged.
    }
动态添加的控件放在if!(this.ispostback)外
去掉  if (!IsPostBack)
        {
to cpp2017(慕白兄):谢谢，这段代码麻烦您帮我调一下，分都送给您了
那就把添加tab的代码放在里面.添加gridview放在外面.

如果把添加tab和gridview的代码放在某个按钮的点击事件中怎么办
