Web Forms :: Exporting Excel File Using DocumentFormat.OpenXml?
Mar 18, 2010
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.
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 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.
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.
how to download excel file containing formula like sum and cell protection from a reportviewer?
I had tried to render the end result from the reportviewer to edit it result before exporting it out but reportviewer is only able to render out as byte format.
I got struck while trying to convert the bytes to a table format where i could add the formula in but to not vaild.
I'm having two grid view and one button on aspx page , on click of export to excel button i want to transfer these grid view data to excel sheet.. My requirement is to trasnfer to same excel file with two sheets(One sheet for one grid view).
I have a problem with exporting three gridviews (main and nested gridview and sub nested gridview) to Excel fromat using ClosedXML (XLWorkbook). I read tutorial on aspsnippets and it works fine for main gridview. i refered in link [URL] ....
But its only for two gridview but i need three nested gridviews export to excel ....
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { gvCustomers.DataSource = GetData("select top 10 * from Customers"); gvCustomers.DataBind();
I was using this UR [URL] for exporting the data to excel. Can I do the following two things while exporting:
1) I want to remove the autofilter options, which are displaying now when you open the excel workbook soon after exporting finishes.
2) Some of the columns which are numerics, are formatted to text by default, and it is displaying a small green rectangular icon at the left top corner of each cell which is very disturbing while viewing the sheet.
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.
I have a project in vb with a gridview in a multiview and i want to save in a workbook excel the gridview displayed data. I have read many articles but in the end i have downloaded the code from URL...and i adapted for my code. The problem is that when i press the ExporttoExcel button it's exporting only this...I cannot figure out that is the problem.
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.
I need to work on opening a DOT (word document template) file, replace the fillers and save it as Document file.
On opening DOT file I am getting "Document File is Corrupted".
Is it possible to work with DOT file using OpenXML.
UPDATE: I am saving DOT file as XML (manually using "Save as.."). Renaming file back to dot, so it is XML file built on WordML. Still trying to open it through OpenXML giving me the same error.
is there any way that i could export multiple tables already formatted into multiple excel sheets. I know how to export data to multiple sheets through dataset while looping through tables, rows and columns and then add styles.
But I really want to export formatted html tables each into seperate sheet
i have a page having 12 gridviews which cell background color depend on another cell value.now the requirement of my project is download to these 12 gridviews in single excel file in multiple sheets like gridview 1 in sheet1 gridview2 in sheet2 likewise,,,,,,,,,,,i have seen your article on downloading multiple gridviews on same page but i want in above mention format........
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.
URL...I now want to turn off all hyperlinks that are in the gridview. How do I do that with this code?
Button on page<asp:Button ID="Button2" runat="server" Text="Export to Excel" OnClick="BtnExportExcel_Click" Font-Names="Arial" style="text-align: center" /> Code behind: Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control) ' Verifies that the control is rendered End Sub otected Sub BtnExportExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
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 report which is created using a .rdlc. And populated using a List object. The report when exported to excel has a problem. The numeric colums show up as text and the tooltip in excel says "The number in this cell is formatted as text or preceded by an apostrophe". How can I get the number to show up as numeric?
