Following link http://www.c-sharpcorner.com/UploadFile/0c1bb2/export-gridview-to-word/[^] , this is my code is export gridview to word.

gridLedgerReport.AllowPaging = false;
            gridLedgerReport.DataSourceID = string.Empty;            
            gridLedgerReport.DataSource = ViewState["grid"];            
            gridLedgerReport.DataBind();
                       
            Response.Clear();
            Response.Buffer = true;
            Response.ClearContent();
            Response.ClearHeaders();
            Response.Charset = "";
            string fileName = "LedgerReportOn" + System.DateTime.Now.ToString("MM/dd/yyyy") + ".doc";
            StringWriter sw = new StringWriter();
            HtmlTextWriter hw = new HtmlTextWriter(sw);
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.ContentType = "application/msword";  
            Response.AddHeader("Content-Disposition", "attachment;filename="+fileName );
            gridLedgerReport.GridLines = GridLines.Both;
            gridLedgerReport.RenderControl(hw);  
            Response.Write(sw.ToString());            
            Response.End();

However, this code is not working for me. As per my understanding, a download Save or Open option was to be shown. However, this code shows no effect on my application. On debugging, the all codes executes but no response.

Any help on how can I export my gridview to word.
Thanks in advance...
