I wrote this codes for export GridView to Excel :
System.Web.HttpContext.Current.Response.Clear();
Response.Buffer = true;
Response.ClearContent();
Response.ClearHeaders();
Response.Charset = System.Text.Encoding.UTF8.EncodingName;
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.BinaryWrite(System.Text.Encoding.UTF8.GetPreamble());
string FileName = Title + ".xls";
StringWriter strwritter = new StringWriter();
HtmlTextWriter htmltextwrtter = new HtmlTextWriter(strwritter);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment;filename=" + FileName);
but file name does not show correctly for non english names(Such as Arabic). How I can save file with non english names?
thanks
Wrap file name With
Server.UrlEncode
for example:
string FileName = Server.UrlEncode(Title + ".xls");
and it works!!!!

Proper Selection of File was not given later i corrected proper file location than i got proper output
I am using ASP.Net and Open office XML and I have been able to set the headers of the excel file.
However, I want to set the value to cells from say D2 to D1000 in a drop down fashion i.e. that the user can only select from a predefined list of values as in a drop down list.
How do I accomplish this?
The code for creating the excel is
List<ExcelExport> mpList = new List<ExcelExport>();
DataTable dt = ListToDataTable(mpList);
string attachment = string.Format("attachment;filename={0}-{1}.xlsx", ddlHealthFacility.SelectedItem.Text + " Excel export ", " ");
using (ExcelPackage pck = new ExcelPackage())
{
//Create the worksheet
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Monthly Plan");
ws.Cells["A1"].LoadFromDataTable(dt, true);
Byte[] fileBytes = pck.GetAsByteArray();
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", attachment);
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
Response.BinaryWrite(fileBytes);
Response.End();
}
I am working on a project, where I want to download gridview row data, but it is not working for me. Here is the code i used for download:
string fileName = "chhattisgarhishafte" + DateTime.Now.ToString() + ".doc";
GridView1.DataSource = dtD;
GridView1.DataBind();
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=" + fileName);
Response.Charset = "";
Response.ContentType = "application/vnd.ms-word ";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.AllowPaging = false;
GridView1.DataBind();
GridView1.RenderBeginTag(hw);
GridView1.RenderControl(hw);
Response.Output.Write(sw.ToString());
GridView1.RenderEndTag(hw);
Response.Flush();
Response.End();
stD is datatble which stores the gridview selected rows.
The errror is:
Control 'ctl00_ContentPlaceHolder1_GridView1' of type 'GridView' must be placed inside a form tag with runat=server.
Please use in form tag in the master page use runat="server"
use this code,its working in my application
if (gv.Rows.Count > 0)
{
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
//Get the HTML for the control.
gv.RenderControl(hw);
//Write the HTML back to the browser.
//Response.ContentType = application/vnd.ms-excel;
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + strFileName);
EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
}
I am working on asp.net 4.0 web application development using c#. I am trying to export the Gridview data to ms word document. I have used the following code.
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=MyWord.doc");
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.ContentType = "application/vnd.word";
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.GridView1.RenderControl(oHtmlTextWriter);
Response.Output.Write(oStringWriter.ToString());
Response.Flush();
Response.End();
The application is running without problems but it returns the data in word like
+ADw-div+AD4- +ADw-table cellspacing+AD0AIg-0+ACI- cellpadding+AD0AIg-4+ACI- id+AD0AIg-GridView1+ACI- style+AD0AIg-color:+ACM-333333+ADs-border-collapse:collapse+ADsAIgA+- +ADw-tr style+AD0AIg-color:White+ADs-background-color:+ACM-507CD1+ADs-font-weight:bold+ADsAIgA+- +ADw-th scope+AD0AIg-col+ACIAPg-FileId+ADw-/th+AD4APA-th scope+AD0AIg-col+ACIAPg-PortalId+ADw-/th+AD4APA-th scope+AD0AIg-col+ACIAPg-FileName+ADw-/th+AD4APA-th scope+AD0AIg-col+ACIAPg-Extension+ADw-/th+AD4APA-th scope+AD0AIg-col+ACIAPg-Size+ADw-/th+AD4APA-th scope+AD0AIg-col+ACIAPg-Width+ADw-
I know it is much similar to html but how could i convert this into actual one. guide me.
this is works for me it requires itextsharp.dll
string FName = "filename.doc";
mygrid.AllowPaging = false;
mygrid.DataSource = datasource();
mygrid.DataBind();
Response.ClearContent();
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", FName));
Response.Charset = "";
Response.ContentType = "application/ms-word";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
mygrid.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
I have created a chart with Mschart.I want to export the created chart to excel.
I'm using following code but when I open it in excel I just see some unknown code instead of chart.
using (var chartimage = new MemoryStream())
{
ChartAmalkerd.SaveImage(chartimage, ChartImageFormat.Png);
ExportToExcel(chartimage.GetBuffer());
}
private void ExportToExcel(byte[] input)
{
string attachment = "attachment; filename=Employee.xls";
Response.ClearContent();
Response.ContentEncoding = Encoding.GetEncoding(1256);
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/vnd.ms-excel";
Response.Buffer = true;
this.EnableViewState = false;
Response.BinaryWrite(input);
Response.Flush();
Response.Close();
Response.End();
}
I have found the same issue and after making several attempts, I was able to find out the correct way. This worked for me and the code is as follows.
string tmpChartName = "test2.jpg";
string imgPath = HttpContext.Current.Request.PhysicalApplicationPath + tmpChartName;
Chart1.SaveImage(imgPath);
string imgPath2 = Request.Url.GetLeftPart(UriPartial.Authority) + VirtualPathUtility.ToAbsolute("~/" + tmpChartName);
Response.Clear();
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment; filename=test.xls;");
StringWriter stringWrite = new StringWriter();
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
string headerTable = #"<Table><tr><td><img src='" + imgPath2 + #"' \></td></tr></Table>";
Response.Write(headerTable);
Response.Write(stringWrite.ToString());
Response.End();
Hope this helps.
I also came across such scenario in one of my project.
Here is the solution.

Add this code for your globalization, this works for me.
Dim info As System.Globalization.CultureInfo = New System.Globalization.CultureInfo("en-US")
Thread.CurrentThread.CurrentCulture = info
Thread.CurrentThread.CurrentUICulture = info
context.Response.ContentEncoding = System.Text.Encoding.UTF8
context.Response.HeaderEncoding = System.Text.Encoding.UTF8
