                this.GridView1.AllowSorting = false;
                this.GridView1.EditIndex = -1;

                // Let's bind data to GridView
                this.BindData();

                // Let's output HTML of GridView
                Response.Clear();
                Response.ContentType = "application/vnd.xls";
                Response.AddHeader("content-disposition",
                        "attachment;filename=MyList.xls");
                Response.Charset = "";
                StringWriter swriter = new StringWriter();
                HtmlTextWriter hwriter = new HtmlTextWriter(swriter);
                GridView1.RenderControl(hwriter);
                Response.Write(swriter.ToString());
                Response.End();
            }
            catch (Exception exe)
            {
                throw exe;
            }
         
        }

But when i execute this method at that time i got this error

C#

Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server.

i got this code from web.
Where i am wrong....
