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 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 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 report displaying the data for an employee. If I wish to generate report for 2 employee, how I can do to make a single report contains both the data? (e.g.: 1st page display data for 1st employee; 2nd page display data for 2nd employee and so on) I need them to be in the same report/pdf file.
Im writing a bit of code that will extract the contents of a gridview to excel. I have all the parts working except for one. In my page_load i fetch the data from the database and then have the user select some options which filters the data and then the gridview gets populated. The problem im having is that the Response call doesnt seem to get the data from the gridview if i enclose the database fetch command within if not page.ispostback in the page_load
I have some test pages where i just fetched the data from the database bound it in a gridview in the Page_load. then on a button click export the data in the gridview to excel. Works fine if i DONT enclose the fetch command within not page.ispostback but outputs an empty excel file if i do.
Now i have to use not page.ispostback in the actual webpages because the users have to make selections which will filter the original dataset. How do i get this to work?
The page is also implementing AJAX if that helps. Here's an example of what i have:
I want to export dataset to Excel. I did the following ways:
1) bind a dataset to a crystal report, 2) export crystal report to Excel Can it be done without displaying crystal report and only Excel file? Or, I have to find out a way export to Excel directly from dataset?
I'm reading an excel file using oledb in my asp.net code (vb).I have no problem going over the data but in one of the cells there is a string that "hides" a hyperlink. I want that hyperlink and not the string...
Is it possible to extract all the report name, thier users, last time they ran, schedules (on demand) and status of those reports from crystal mangement console or crystal enterprise. Right now, I did this, I copied all the report names by doing <ctrl> a and pasting them in excel spreadsheet, but to find out which user is using that particular report is very tedious. I have to go thorugh each report and click on it and then I see tabs, of of them says properties, history, process... and users. I get users this way. I have around 500+ reports. This can become very tedious task. I was wondering if their is any other way to find this out.
