后台代码：

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            databind();
        }
    }
    public void databind()
    {
        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Conn"].ToString());
        SqlCommand cmd = new SqlCommand();
        cmd.Connection = con;
        cmd.CommandText = "Select top 10 * From Customers";
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataSet ds = new DataSet();
        da.Fill(ds);
        this.GridView1.DataSource = ds.Tables[0];
        this.GridView1.DataKeyNames = new string[] { "CustomerID" };
        this.GridView1.DataBind();
    }
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#ff9900'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");

        }
        if (e.Row.RowType == DataControlRowType.Header)
        {
            e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#ff6600'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
        }
