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:
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 need the code for exporting aspx report page(static content without any html component but contains css style) to excel page without using any asp.net component like datagrid or any other.Please send me the complete code.
On Previous version of my application, if I want to export my data from SQL Server to Excel 2003 file, I just retrieve data from the SQL server and then straight away show "Open, Save, Cancel" dialog box to get the data on Excel 2003 Format. Here is the existing code in C#.
public void ExportToExcel(string StrFileName, DataTable dt) { if (dt!= null && dt.Rows.Count > 0)[code]....
but when I want to Export to Excel 2007 format with the same. I don't have any Idea to export 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.
I am loading documents into our Oracle database and then retrieving them for the users to view. So far PDF, DOC, XLS, CSV, etc. all perform as expected, however; DOCX, XLSX, etc. files have one annoyingly persistent issue. When the document is downloaded by the user and they open it you get the first in a series of messages: The file 'thefile.docx' cannot be opened because there are problems with the contents. Details: The file is corrupt and cannot be opened. and then: Word found unreadable content in 'thefile.docx'. Do you want to recover the contents of this document? If you trust the source, click Yes. After clicking yes the file opens and all of the content appears correct. Including images, formatting, tracked changeds and comments, equations, etc. I have tried multiple methods along these lines to no avail. I simply want the files to open without the false-positive error messages. I am using VS2010, with the website targeted at .Net Framework 2.0.
objConn = New OracleConnection(gstrConnectionString) objConn.Open() cmd = New OracleCommand cmd.Connection = objConn cmd.CommandText = "select DOCUMENT_NAME,DOCUMENT_TYPE,DOCUMENT from DOCUMENT_TABLE where DOCUMENT_ID='" & strDocumentID & "'" dr = cmd.ExecuteReader dr.Read()
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.
When i export the data table to excel 2003 i get the output in a very fast manner and when i want to use the same in excel 2007 debugging gets stopped and nothing happens.... It does not show any errror on it to. When i slowly debugged i find that in saveas() it takes longer time and it seems like execution gets stopped in this process.
Its like in new window it shows loading for more than 10 min and after some time the particular window gets closed and nothing happens can anyone tell me what can be wrong.When the same code works great when i export to 2003.
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
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?

I am attempting to read data from an uploaded spreadsheet using ACE.OLEDB. The code, which is running fine on dev and test machines for XL2003/2007 reports "Exernal table is not in the expected format" error on connecting on the production server for XL2007 only.The code is

I'm really stuck tryign to figure this out. Converting XLS to CSV is no big deal or at least it seems that way. However, trying to go xlsx to csv seems to be more difficult. For grins, I grabbed some code that is supposed to read a sample xlsx file and convert that into a gridview called GridView1. I figure it can't be much different to turn that into CSV.
