Exporting Multiple Tables In A DataSet To An Excel File With Multiple Sheets?
Jul 8, 2010
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.
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.
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........
I used this coding for export to excel, by using this coding i got only 65,536 rows only. How to bind more than 65,536 records or how to move the balace records to sheet 2 by using this method.
Protected Sub btnExportExcel_Click(ByVal sender As Object, ByVal e As EventArgs) Dim ars_stock As New DataTable ars_stock = cls.FillDataTable("select top 70000 * from spal..po_acc_details") Response.Clear() Response.Buffer = True
I have a lot of excel sheets which columns are slightly different, i want to import all of these sheets (one at a time) into ONE SQL TABLE. I'll give an example : Say ive written the required program and called it Excel2sql converter. So Excel2sql takes an excel sheet and create a database table with the data of that excel sheet, For example say i have the following excel sheet:
Excel_Sheet_1 ----------------------------- FirstName MiddleName LastName John A. Smith
when i run Excel2sql (Excel_Sheet_1), a database table should be CREATED for me with the following data in it:
FirstName MiddleName LastName John A. Smith
Now, when i run my program again with the following excel sheet:...................
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 an C# ASP application I am writing that needs to have the capability to import a generated excel or a comma delineated sheet each day. A clerk will have this job each morning so it doesn't need to be automated. My problem in trying to understand the solution to this is that the 1 sheet contains loan information, including customer information all in the same sheet. I would like to send certain columns to update information in the loan table and send other information to update the customer table. I need it to create relationships when new loans appear in the spreadsheet.
I have 5 tables of which one has a primary key called "pid" as follows in patientdetails table the pid of a patient is used to compare the pid in remaining tables so the data in matching pid records can be stored in dataset. I tried using stored procedure to get them together in one dataset but it just doesent happen. This is my stored procedure,
I think the execution doesent proceed after the first if exists statements, because only the data in patientdetails is stored in dataset. and one more thing. all test tables need not contain a data against every pid in patientdetails table.
Does anyone have some really great tutorials on how to use link with datasets that contain multiple tables that utilise primary key and foreign key relations? For eample
Table1 - id (PK) - language Table2 -id (PK) -programmingword Table3 -id (PK) -languages_ID (FK) -pgrammingword_ID (FK) -translatedword
Linq search for: Table3.translatedword where Table1.Language ='french' and Table2.programmingword = "yes" does this make sense? im looking for exampes/ tutorials for how to do this? or can anyone recommend any good books on linq?
