This is an ASP.NET web app built using VS2008. I created a standalone class with a method that exports the entire page, text fields, gridviews, images, everything to an Excel worksheet. It works fine. When I dropped the same class in another web app and tried to call it from a page, I get this error message:

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;

I am trying to write a bit of code that will export the current contents of a gridview to an excel file on the local system. I've looked at several examples on how to do it and implemented it. However, i am unable to get the gridview to export the data.
Here's the basics of what i am doing:
I'm using httpcontext.current.response to specify the file contents and filename. creating Stringwriter and htmltextwriter objects.
then rendering the table into the htmlwriter then rendering the htmlwriter to the response.
however, regardless of how large or small the table i am working with is, i keep getting the following error:
[Code]....
Visual Studio opens a file called ScriptResource.axd and the error is noted in the following section of code at the throw error line.
[Code]....
I have included the Public Overrides Sub VerifyRenderingInServerForm(ByVal ctl As Control) method as suggested by others but this has not resolved my issue. I am not sure how to proceed.
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.

I need to export asp.net page toexcel 2007. when i wrote the code as below:
protected void Button2_Click(object sender, EventArgs e) {Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.Charset = ""; Response.ContentType = "application/vnd.xls"; System.IO.StringWriter string
Write = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter html
Write = new HtmlTextWriter(stringWrite); div1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString()); Response.End(); }
publicoverride void VerifyRenderingInServerForm(Control control) {
} and
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="poprint.aspx.cs" Inherits="print_poprint" EnableEventValidation="false" %>
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.

I have a gridview that I am exporting to an excel file. When I open the excel file, the alternating row color extends to the end of the excel table, but I only want my 6 data columns to be formatted. How can I limit the formatting?
My gridview:
<asp:GridView ID="grdExportable" runat="server" BackColor="White" ForeColor="Black"
Width="1100px" AutoGenerateColumns="False" Visible="False">
<PagerSettings Mode="NumericFirstLast" />
<Columns>
<asp:BoundField DataField="ActivityDateTime" HeaderText="Date/Time" />
<asp:BoundField DataField="TestName" HeaderText="TestName" />
<asp:BoundField DataField="RoundSerialNumber" HeaderText="RoundSerialNumber"/>
<asp:BoundField DataField="RoundType" HeaderText="RoundType"/>
<asp:BoundField DataField="LotNumber" HeaderText="Lot/StockNumber" />
<asp:BoundField DataField="Notes" HeaderText="Notes" />
</Columns>
<SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#6C0000" Font-Bold="True" ForeColor="White" />
<AlternatingRowStyle BackColor="#CCCCCC"/>
</asp:GridView>
My export method:
private void ExportGridView()
{
string attachment = "attachment; filename=Activity Report.xls";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grdExportable.Visible = true;
grdExportable.RenderControl(htw);
grdExportable.Visible = false;
Response.Write(sw.ToString());
Response.End();
}
I am exporting an aspx page as an xls (excel) file.
I have everything working fine, but am wondering if there is a way to section some data from the aspx page into different excel worksheets?
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 have the following code on the client side for retrieving data from the HTML Table and then send it to the server through the page method:
[code]....
But I get this expcetion: Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.
how to handle this issue?

View 5 RepliesI've got an .rdlc report which I print from my .net app (C# Visual Studio 2005), where I use a RemoteReportPrinter object. I give it as parameters the server name, report name, report parameters, etc. Works fine. My question is, I would live to do an analagous export of that report to Excel. Set it up exactly the same, but have it export to Excel rather than print, probably using some other type of object than RemoteReportPrinter.

But I really want to export formatted html tables each into seperate sheet
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.
