Databases :: Error While Exporting Data From DataSet To Microsoft Excel?
Apr 14, 2010
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 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'm looking for a way to parse excel into Asp.Net, the problem I'm experiencing same as in[ URL]
I've searched all web, but no1 seems to have an answer
here's the error
The Microsoft Jet database engine could not find the object 'Cities'. Make sure the object exists and that you spell its name and the path name correctly.
i did the mysql data export into excel in row wise when button click... here i want the same data export into columns wise..i used datatable and dataset for this function.. here i need all data should export in column..here i used some code..
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.
I catch the error of "Property Evaluation Failed" for the sentence "Response.End" in the following code.
Sub exportToExcel(ByVal _DT As DataTable) Dim dt As DataTable = _DT Dim attachment As String = "attachment; filename=userlist.xls" Response.ClearContent() [code]....
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'm exporting data to Excel. I've to put some headings, some data from datatable and again some footer text. For that I'm using following Code. It works fine locally but when I publish it it gives error while saving excel file as I'm hosting it on shared server.
I have a Telerik Radgrid i export the data in RadGrid with gridexporting property of radgrid in Excel 2003 i.e .xls but the problem is that my some client's computers have excel 2003 and some have 2007 when this exported radgrid excel data going to be opened in 2007 this shows some message that due to .xls file going to opened in 2007 but after clicking ok button on message its allowed me to open the file, i just wanted to stop this 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
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 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 get this error when exporting report to excel format., The data returned is vast. The date is for 6 months.Server Error in '/QSecureV2' Application For security reasons DTD is prohibited in this XML document. To enable DTD processing set the ProhibitDtd property on XmlReaderSettings to false and pass the settings into XmlReader.Create method.Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code
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'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.
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 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 am developing a simple web app on Visual Studio 2010 on Vista, using Local IIS. When I ran I got this error message:
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
For this app, I did the following.
-- Add Reference of Microsoft Excel 12.0 Object Library from WebSite option on Visual Studio 2010.
-- Here is the code: (Error occured @ Dim xii2 As New Excel.application). The identical code and idential Add Reference were fine when developed under window .net asp

i am trying to upload excel data into datbase i am getting jscript error but data is uploading sucessfully.I am using ajax extension. Same code i am using for uploading text file data but i am not getting any error.
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.
