Exporting DataSet To Excel Directly
Dec 14, 2010
trying to export a dataset to excel directly. I'm repeating, it's a dataset to excel (NOT DATA GRID OR GRID VIEW TO EXCEL). The problem I face is formatting. I'm exporting the excel which has aroung 13 columns.
A column should be in dd/MM/yyyy 00:00:00 format. Time will always be 00:00:00. It is exporting in correct format only, but for example when the date is Jan 05, 2010, when it comes from database it shows correct format as05/01/2010 00:00:00. When it binds, it binds as 5/1/2010 00:00 which is not suppose to happen.

In C# ASP.NET 3.5 web application, I need to export multiple datatables (or a dataset) to an Excel 2007 file with multiple sheets, and then provide the user with 'Open/Save' dialog box, WITHOUT saving the Excel file on the web server.
I have used Excel Interop before. I have been reading that it's not efficient and is not the best approach to achieve this and there are more ways to do it, 2 of them being: 1) Converting data in datatables to an XML string that Excel understands 2) Using OPEN XML SDK 2.0.
It looks like OPEN XML SDK 2.0 is better, please let me know. Are there any other ways to do it? I don't want to use any third-party tools.
If I use OPEN XML SDK, it creates an excel file, right? I don't want to save it on the (Windows 2003) server hard drive (I don't want to use Server.MapPath, these Excel files are dynamically created, and they are not required on the server, once client gets them). I directly want to prompt the user to open/save it. I know how to do it when the 'XML string' approach is used.

I am usig ADO.NET to fetch a Dataset and then exporting the data to excel using Response.Write with response type set as excel. However when I run the application I am getting the following error in the browser."Cannot view XML input using XSL style sheet. Please correct the error and then click theRefresh button, or try again later."Anybody has any idea on why do we get this error and any pointers to resolve this error? By the way the same code does works on another machine, it's just not working on few machines.

I was in need of exporting multiple tables in a DataSet to an Excel file with multiple sheets. I found a very good article in [URL].[URL] was able to successfully export each of my datatables in the dataset to excel worksheets. This solution worked for small number of rows. But when the data got larger I am consistently getting the system.outofmemoryexception. THis is because the code is using up the memory when creating excel.
Does anyone have another option to do the above?

I have created several applications now allowing the user to export to excel, word, pdf, etc. But this one is a little different, the client wants to have functionality that would directly export to excel as an attachment in an email. Basically my question is, can I create the excel file without storing it to server prior to attaching and sending out the email? Or do I have to save a copy on the server before I can attach it?

I'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.

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.

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.

What I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.

Here is my code:

I have multiple gridviews to be exported to excel. 1 gridview per worksheet.
How to do that ? ( or in general how to write an html string to a worksheet )
This is to be done in asp.net , server side.
I can create multiple worksheets via epplus.codeplex.com nicely, but it works on cell level. I could export DataTable, but how to export Gridview's HTML ?

I've been working on this for a while and everything that I have read seems to tell me to use the same setup. I have been able to export the data to an xls file on my local C drive but that won't work when hosted on the server as I'll want users to export their data to their local machines as well... I guess the issue I'm having (or at least what I think am having) has to do with my response.end() function. I'll give you my code that works and the one that doesn't... In the end they will both do the same thing...Here is the code I've been playing with for my button:
[Code]....
Now here is where it will at least save on my local drive via a button in my drop down menu:
[Code]....
I need to prompt the user to save the file to a location and perhaps be able to name the file etc

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 asp.net page that generates a report. For better or for worse, the entire thing is generated using nested tables. I am able to export the page to excel, however I lose all my formatting (can't set column widths, etc). Is there a way to handle this? I'm open to adding any goofy MS Office -specific tags that are required to the html side of it.
If this isn't feasible and if anyone has any other ideas, the requirement is that users need a report that:
a) They can manually touch up with some personalization / area-specific data
b) Needs to be hide/show columns based on user's location
c) Needs to run from the web site.
