i have data in sql server i want to export to data with asp.net C#
View 3 RepliesIn 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 have a problem that I have been trying to solve the past two days, but I cannot figure it out...I have a folder which will have 60-70 Excel Files or CSV Files (they are right now). There are no headers in them, but they all have the same # of columns and the columns are in the same order in each fileI need to read each file in the folder, grab the data from the file and put it in a Database file. So all files will be read and then the data from them I guess put in a DataSet and then put into a Database (SQL).

Problem is that its not raising file download and hence no export is taking place.The same code works fine in a normal method.But with the webmethod its not working.
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.

View 1 RepliesI 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.
Does anyone have another option to do the above?

When my site runs the following code it works just fine 99% of the time.
[Code]....
The command is calling a SQL Server 2005 stored procedure that takes 20 parameters and returns 6 tables of about 5-50 rows each. The paramters are all NVARCHAR, INT, or BIT data types. Only one of the parameters is Input/Output. There is a total of about 100 rows returned. Normally this takes a fraction of a second, but for some queries, it times out after 30 seconds.
When I run the exact same query in the Management Studio query window it takes 1 second.
what I can do to get the same performance from .Net as I am getting from Management Studio?
