How to avoid downloading files to the download folder and download to other specific folder only in c#

I am trying to convert the gridview to excel and downloading the excel sheet to my computer's specific folder in my c# application.
The problem is: The file is getting downloaded at both the places.The destination folder and also the download folder.
the code for this is:
private void ExportToExcel(GridView GrdView, string fname)
{
Response.Clear();
Response.AddHeader("content-disposition", "inline;filename=" + fname + ".xls");
Response.Charset = "";
Response.ContentType = "application/OCTET-STREAM";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite =
new HtmlTextWriter(stringWrite);
GridView1.RenderControl(htmlWrite);
string renderedGridView = stringWrite.ToString();
File.WriteAllText(#"C:\\Users\abc\\Desktop\" + fname + ".xls", renderedGridView);
Response.Write(stringWrite.ToString());
Response.End();
}
How to avoid the files getting downloaded to the download folder?
Please help!
Thank you

The answer would be to pick one: either render the control to a string and output to Response OR WriteAllText. If you want to use the WriteAllText to save the file to a determined location, then perform the action and pop up a notification to the user that the file was saved.

Illegal characters in path c# error

I am getting the error
Illegal characters in path
for the code below . Please help me out.
response.Clear();
response.Charset = "";
Response.ContentEncoding = System.Text.Encoding.Default;
// set the response mime type for excel
response.ContentType = "application/vnd.ms-excel";
string sFileName = "Testeeeeee.xls";
response.AddHeader("Content-Disposition", "attachment;filename=\"" + sFileName + "\"");
// create a string writer
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
// instantiate a datagrid
DataGrid dg = new DataGrid();
dg.DataSource = DS.Tables[0];
dg.DataBind();
dg.RenderControl(htw);
string sPath = #"E:\CR-12\Test.xls";
File.WriteAllText(sw.ToString(), sPath);// I get the error at this line
response.End();

The parameters are inverted. Do it as follows:
File.WriteAllText(sPath,sw.ToString());

You've got the parameters to File.WriteAllText mixed up. The first one is the path, the second is the contents. You need
File.WriteAllText(sPath, sw.ToString());

The call to
File.WriteAllText(sw.ToString(), sPath);
has the wrong parameter order. It should be
File.WriteAllText(sPath, sw.ToString());

For others receiving this error, make sure you are using backslashes correctly since they are also escape characters. A single backslash can result in this error. Use 2 backslashes to properly output a single escaped backslash.
Ex:
System.IO.File.WriteAllText("C:\\file.txt", output);

The issue is probably a security related one. Your webpage wouldn't be default have access to the E drive.

ASP.NET: Write a table (and checkboxes) to a word document

I am writing an ASP.NET Application in c# and I'm trying to write a table to a word document.
I use currently the following code to write to a word doc:
string strContent = "This content goes to the word document";
string attach = "attachment; filename=wordtest.doc";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/msword";
HttpContext.Current.Response.AddHeader("content-disposition", attach);
HttpContext.Current.Response.Write(strContent);
HttpContext.Current.Response.End();
HttpContext.Current.Response.Flush();
Now, my question is if anyone knows how I can write a table to a word document?
And second question is if anyone knows how to write checkboxes to a word doc (like you copy it from a website and paste it in word)
Thanks in advance!

Word can recognise HTML. So you can simply write any HTML to MS WORD with Response.Write(); Method. Here is code sample.
string strBody = "<html>" +
"<body>" +
"<div>Your name is: <b>" + txtName.Text + "</b></div>" +
"<table width="100%" style="background-color:#cfcfcf;"><tr><td>1st Cell body data</td><td>2nd cell body data</td></tr></table>" +
"Ms Word document generated successfully." +
"</body>" +
"</html>";
string fileName = "MsWordSample.doc";
// You can add whatever you want to add as the HTML and it will be generated as Ms Word docs
Response.AppendHeader("Content-Type", "application/msword");
Response.AppendHeader ("Content-disposition", "attachment; filename="+ fileName);
Response.Write(strBody);

Can't export just a part of my aspx page on C#

I am trying to export just a table that is contained on my page. I have some filters above it but when exporting, all the text and filters are copied into this file.
This is the code:
tableCreateOrders a = new tableCreateOrders(dtReportColumns, 2, 10);
divResult.Controls.Add(a.displayTable());
Response.ContentType = "application/ms-excel";
Response.AddHeader("content-disposition", "attachment; filename=orders.xls");
Response.Write(a.displayTable());
a.displayTable() is the object containing the table, but the filters are defined on the .aspx so there is no way the command take it. Is there anything I am doing wrong? I'll really appreciate any suggestion.

This is what you need. Remember to ClearContent before and End after.
Response.ClearContent();
Response.ContentType = "application/ms-excel";
Response.AddHeader("content-disposition", "attachment; filename=orders.xls");
Response.Write(a.DisplayTable());
Response.End();
