Forms Data Controls :: Getting Error When Exporting GridView To Excel?
Jul 15, 2010
I am exporting GridView to Excel but keep on getting a pop up "The file you are trying to open, 'somefile.xls' is in a different format than specidied 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 I click "yes" the file opens fine. But why I am getting the pop up at the first place.Also as I have Office 2007 on my machine
GridView1.DataSource = dv;
GridView1.DataBind();
Response.Clear();
Response.Buffer = true;

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 exporting a Gridview to excel. I get all the gridview header and content in excel in addition to that i need to add a header text like report name in header of the excel sheet with line break in header.
I tried the solution in this link [URL] by adding
Table.Caption = "Header Text"
Table.CaptionAlign = TableCaptionAlign.Top
but i get error Reference to a non shared member requires an object reference.

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.

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.

I am trying to work through a sample of exporting a gridview to an excel spreadsheet.I found the code below on the internet. I pasted it into a test.aspx page. I need to establish a connection to the NorthWind Database. Or if you have a better example of exporting a gridview to excel, share. Here is the location of the northwind.mdb on my pc: (and is this sample looking for an access database or a sql database...what is the filetype of a sqlserver database?) See code below

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]()

I want to export my GridView, but also, replace any CheckBox controls that are rendered automatically with T/F fields in the process, with LiteralControls, so that everything is text in Excel.
See my below code. I'm not getting any errors, but the code is just not working. The resulting spreadsheet contains the CheckBox fields anyway.

I am able to save excel sheet from GridView perfectly. 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 tried pulling URL from web.config however I am not sure where to add that in the following code
<asp:GridView ID="bestpractgrv" runat="server" AutoGenerateColumns="False" CellPadding="3" GridLines="Vertical" Width="100%" BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" PageSize="10" AllowPaging="True" OnPageIndexChanging="OnPaging" DataKeyNames="iID">
<AlternatingRowStyle BackColor="Gainsboro" />

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?
