                        <Columns>
                            <asp:ImageField AlternateText="员工头像" HeaderText="员工头像" DataImageUrlField="photo">  // 绑定数据
                            </asp:ImageField>
                        </Columns>
                        <RowStyle BackColor="#EFF3FB" />

        SqlConnection con = new SqlConnection();
        string sql = "select * from tb_user";
        SqlDataAdapter sda = new SqlDataAdapter(sql, con);
        DataSet ds = new DataSet();
        sda.Fill(ds,"tb_user");
        DataRowView drv = ds.Tables["tb_user"].DefaultView[0];
        this.GridView1.DataSource = drv;
        this.GridView1.DataBind();
        this.GridView1.Columns[0].HeaderImageUrl =Convert.ToString(drv["photo"]);
//此处用到了HeaderImageUrl 来从数据库里得到图像的路径来显示图片

    }
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        this.GridView1.PageIndex = e.NewPageIndex;
        this.GridView1.DataBind();
