It displays message as shown
The file you are trying to open is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
When yes is clicked it opens in excel but in some other format I think for I cannot AUTOSUM or sum the values result always as zero for numbers appears as text as " 222" . even if i try to format cells with numbers it does not works.

when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.

I'm working on a web app and need to stream various files. I can do pdfs, images, and older Office documents. However, when I try to do with 2007 documents, it breaks. Here is my code:
Response.Buffer = true;
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
switch (FileExtension.ToLower())
{
case "pdf":
Response.ContentType = "application/pdf";
break;
case "doc":
Response.ContentType = "application/msword";
break;
case "docx":
Response.ContentType = "application/vnd.ms-word.document.12";
break;
case "xls":
Response.ContentType = "application/vnd.ms-excel";
break;
case "xlsx":
Response.ContentType = "application/vnd.ms-excel.12";
break;
default:
Response.ContentType = "image/jpeg";
break;
}
Response.BinaryWrite(buffer);
The error that I get is:
An invalid character was found in text content. Error processing resource 'http://DomainName/GetFile.aspx.

On two of my web forms I have the ability to export a gridview to an excel file. On my local machine. it works. So when I click an image button it gives me the option of opening or saving a gridview as Excel.
However, when I run on the web server. It does not give me the option to open or save, it just opens the gridview as an excel document when the button is clicked.
Even stranger: I have this running on two separate forms. On one form when it opens the gridview as an Excel file it includes a tool bar, so that If a user wishes they could do a 'file', 'save'; However the other one does not have a tool bar?
Ideally I would like them to get the prompt like on the local machine, to open or save.

I have a gridvidew (GV2). I want the user to be able to export the contents of this gridview to an excel spreadsheet for offline processing.
Here is my subroutine:
[code]...
On clicking the ExcelButton I get the error message:
Control 'GV2' of type 'GridView' must be placed inside a form tag with runat=server.
The control GV2 is in fact inside:
<form id="form1" runat="server"></form>

This is an ASP.NET 3.5 project being created with VS2008. One page contains a gridview with six columns. One of the columns displays standard, 17 character , Vehicle Identification Numbers (VIN). The VIN numbers display normally when the page is rendered. However, when the gridview is exported to Excel, the VIN numbers change. For example, in the gridview, the VIN might be 12345678912345678But when the gridview exports into Excel, that same VIN becomes 1.23457E+16The value of that Excel cell changes to 12345678912345600, changing the last two digits from 78 to 00. It does this for every VIN in the gridview table.I did some Googling but couldn't find anything specifically on this issue. Has anyone seen it before? Is there a way to format the column in the gridview so that Excel will accept it as literal text? I tried programmatically adding a style called 'text' to that column but that had no effect on the outcome. All of the other columns are behaving normally.

However, I need to add one custom column, which will be URL of a file on sever, I am not allowed to add URLs directly in the table (as per company's development policies).

I finally managed to export a gridview to an excel sheet.
Next, how can I remove the column width and alternatingrowstyle color (or all formatting if it is easier) "programatically" before exporting it to excel?

I am trying to export a gridview that is returned from a search form. The gridview also has paging enabled. In order to export the records from all pages in the gridview I had to turn off paging and do a databind, but instead of only exporting the search results it exports all the records in the gridview.
How can I only export the records from the search results, but also the make sure the records on the different pages export also?

I realized this has been asked multiple times before, but I still haven't been able to get it to work. I'm trying to export a Gridview to Excel without losing leading zeros. Here is my code. Add added the STYLE lines to try to fix the problem.
Dim attachment
As
String =
"attachment; filename=Awards.xls"
System.Web.HttpContext.Current.Response.ClearContent()
System.Web.HttpContext.Current.Response.AddHeader("content-disposition", attachment)
System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel"
Dim sw
As
New StringWriter()
Dim htw
As
New HtmlTextWriter(sw)
gv.RenderControl(htw)
System.Web.HttpContext.Current.Response.Write(sw.ToString())
Dim STYLE
As
String =
"<style> .text { mso-number-format: ; } </style> "
System.Web.HttpContext.Current.Response.Write(STYLE)
System.Web.HttpContext.Current.Response.[End]()
