I used your code over here [URL]
for creating a csv but the csv that gets created is blank. My gridview gets populated so I don't think any problem with that not getting data from Access database. I also tried the code sample you have on this website and checked my code against yours.
My Header Text is always blank. Below is my code
Response.ContentType ="application/pdf"
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf")
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Dim sw AsNew StringWriter()Dim hw AsNew HtmlTextWriter(sw)
gridview1.AllowPaging =False
[Code] ....

how do you handle null data on gridview? and also the white spaces, it seems that the white spaces are converting to " "
Note: i can't replace the because i have 1 column thats in html form.
I have a requirement that i need to remove the columns from gridview which are blank but at remove funtion it gives me error so i make that columns visible false now its working fine but at the time of exporting data from gridview to excel it also export that visible= false columns in spredsheet and i don't want that blank or hidden column in my excel sheet

I found a site which indicates they can export a GridView as Word, Excel, PDF, and CSV. The PDF uses an external library (iTEXT), and I have not tested that. [URL] ....
The CSV worked for me as specified. But I am having trouble with the Word and Excel portions. The code for the Word sub is
Code:
Protected Sub btnExportToWord_Click(sender As Object, e As EventArgs) Handles btnExportToWord.Click
Dim s As String
Response.Clear()
Response.Buffer = True
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.doc")
[Code] ....
The marked line above triggers an error which states
Code:
Control 'MainContent_GridView1' of type 'GridView' must be placed inside a form tag with runat=server.
Note, that the code never gets the Response.Output.Write line, but the file is downloaded, and looks correct.
My real need is to download the excel file, but it has the some behaviour. It fails at a similar RenderControl statement, but does download the file, although Excel indicates it is in a non-standard format (but looks fine when opened. I can upload that code too, but the Word one above is simpler.
Exporting the GridView to various file types. I have got the PDF working great and also want to add Excel. When I use the code I get a message that the file I am trying to open is a different file format from the extension I am trying to open. If i click OK it opens and alls is fine. Trying to get rid of this errors so customers and sales staff doesn't see it. Excel is version 2010.
View 1 Replieswhen 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 my exporting data through dataset to excel. But one column say awb no having datatype nvarchar contains long int no say : 123456789012345.
Then instead of displaying this no in numeric format(123456789012345) it is displaying in exponent form(1.23457E+19).
Is there any way to stop this i want data in numeric format (like this 123456789012345).
I have created an Excel 2007 spreadsheet using DocumentFormat.OpenXml.Spreadsheet. This file is supposed to be used as an attachment to an email message. However, I get errors when opening it stating that this file cannot be opened by using Microsoft Excel. "Do you want to search... online..?" I want to save this file in Excel 2003 format so I won't get that message. What do I do? I don't want users having trouble reading the attached Excel doc.

I have a web page with a gridview control and a button for Exporting to Excel
I get following error when exporting to Excel.
"The file you are trying to open, 'someFileName[1].xls, is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"
Clicking Yes opens the file. I would like to avoid showing the above error to the users.
Following code is used from the click event. I've left the commented code here to show what I've tried based on results from internet search. I have Microsoft Office Excel 2007 on local PC.

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.

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.

Very new to C# although I have alot of older coding experience. Not much object orientated programming though. Anyways, I have a .net program I'm working on, basically to work on my skills although it will prove to be useful. I am keeping track of my work schedule. Currently, I am populating a datagridview from a sql 2008 express db. My columns are: date worked, hours, paid, and paidon. What I want to do is add an empty row whenever the date corresponds to a date that is "Monday". My goal is to line break every week. So that each work week (Mon-Sun) is seperated by a blank row. I would rather not actually have this blank row in the database. I would like the gridview to do this on the fly. Here is my gridview code in my default.aspx file:
