<body>
    <form id="form1" runat="server">
    <div style="width:600px;height:400px;" id="div1">
        <asp:GridView ID="GridView1" runat="server" Height="300px" Width="200px">
        </asp:GridView>
        </div>
    <script language="javascript" type="text/javascript">
       document.getElementById("div1").contentEditable = true;
       document.execCommand('2D-Position', true, true);
    </script>
    </form>
</body>
</html>后台代码：

using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            GridView1.Style.Add("position", "absolute");
            GridView1.DataSource = GetDataSet();
            GridView1.DataMember = "testtable";
            GridView1.DataBind();
        }
    }

    private DataSet GetDataSet()
    {
        DataTable dt = new DataTable("testtable");
        dt.Columns.Add("Col1", typeof(int));
        dt.Columns.Add("Col2", typeof(string));
        dt.Columns.Add("Col3", typeof(string));
        dt.Columns.Add("Col4", typeof(string));

DataRow dr;

        for (int i = 0; i < 10; i++)
        {
            dr = dt.NewRow();
            dr[0] = i;
            dr[1] = "Val" + i.ToString();
            dr[2] = "Val" + i.ToString();
            dr[3] = "Val" + i.ToString();
            dt.Rows.Add(dr);
        }

        DataSet ds = new DataSet();
        ds.Tables.Add(dt);
        return ds;
    }
