Forms Data Controls :: Error When Exporting To Excel - File Trying To Open, '[1].xls, Is In A Different Format
Oct 21, 2010
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 found a few examples online and followed them, but wasnt getting any results, just errors..Here is what i have in my button event that i want to use to create the files..
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 building a User Control that will allow a user to select input parameters, run a query and then view the results in a GridView control. That part is obviously very easy. However, I've been asked to also provide the option of viewing and/or printing the data in a PDF, Excel or CSV file format.
Are there any .Net 2.0, built-in classes that allow for exporting and printing data in these formats in Visual Studio 2005?
A couple of years ago, I worked on a website that offered this functionality in Crystal Reports, but on this particular assignment, we aren't currently using Crystal - I'm not at work right now, and I can't remember if we're running the "Standard" or "Enterprise" edition of Visual Studio.

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 following article in aspsnippets to upload excel file ,it is working fine for 2007 format of excel but displaying error "External table is not in the expected format." for 2003 format
I need a way to export data from MySql database (or simply from DataTable) to Excel and set colors of particular rows based on one of the fields' content.

[Code]....
But I don't know how to set colors to particular rows. Also, I don't know how to make Excel treat text fields that look like numbers as text to avoit scientific notation.
I currently have a data grid that exports to Excel on an ASP.NET page (which is used for reporting purposes) which works great until we put it under the stresses of a full scale production environment. With a multitude of users using it it seems to fill up the server memory quite quickly since the data thats being pulled is rather large. The requirements of the page are: The data needs to be queried and exported to excel, so theres no point to getting around that. I've noticed that xls files are rather large in comparison to their xlsx counter parts, using xlsx files would be fine for my application. I've noticed that xlsb (Excel binary) are even smaller(approx 25% the size of the their xls counterpart). Is there anyway to change my code to export to xlsb (first choice) or xlsx rather than xls? I think it has something to do with Mime Types but I'm not positive.
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 am creating some Graphs using Asp.net Charting control. I need to export the charts created to excel. These charts are going to be saved as images. I am able to export the Graph along with other details successfully using the foloowing code...
Response.Clear(); Response.Buffer = true; Response.AddHeader("content-disposition", "attachment; filename=Sample.xls"); Response.Charset = ""; Response.ContentType = "application/vnd.ms-excel"; StringWriter stringWriter = new StringWriter(); HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter); Table1.RenderControl(htmlTextWriter); htmlTextWriter.WriteBreak(); string test = Server.MapPath("~/");.......
If i try to open this excel file in any other system, then the image (i.e, charts) wont be available. But the excel shows the image only in my system(where the image is available in hard disk) .
