View 2 RepliesExporting To Excel From VS 2008 Error
Jul 13, 2011I have a routine in VS 2008 that exports data to an excel spreadsheet. This has been running without any problems for months. Now I am getting the 'cannot expand named range' error. The strange thing is that it doesn't happen all the time. I can export the data 2-3 times and it works fine but the fourth time I get the error. There is no rhyme or reason. We have upgraded to Office 2010 recently but I updated the excel reference in my project to Microsoft Excel 14.0 Object library. Even if that was an issue why would it work sometimes and other times not? [code]

Exporting An Excel File By Getting The Layout Of A HTML Page?
Nov 13, 2009In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < b>Column Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?

.net - Exporting To Excel Removes Leading Zeros. Css Styles To The Table Does Not Carry Over To The Excel Export?
Aug 4, 2011I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.
View 2 RepliesExporting To Excel - Get Excel To Return Down A Row And Display The Next Product Within The List Box?
Apr 16, 2011I am building an ordering system for my job. The idea is that the customer will put in a stage name for an item. That stage name is then interpreted by the program.The product id and the amount the customer wants to order is placed in a list box on the form. There are a couple of buttons, ADD, REMOVE, CLEAR, and EXPORT. The user input is handled by input boxes. When the user pushes the EXPORT button, excel should open and list out the interpreted product codes with the corresponding amount to order. I can get excel to open, but I can not get excel to display more than one line. It will display the first product, but then it comes up with an unhandled exception.I can not figure out how to get excel to return down a row and display the next product within the list box.

Exporting A DataGridView To Excel?
Mar 13, 2006I have a datagridview(DGV) which contains data based on a user selections from a pre-defined dataset
In point form:
User starts program
program builds datatable
user opens file and program read all data from file into the dataset.datatable
user defines the data they want to see
program displays datagrid based on dataset.datatable and user choices. (basically it displays the whole dataset and removes unwanted columns
ecords)
I want to be able to export the datagrid to excel (not sure which method yet). I have tried the excelexporter component i found somewhere on the msdn forums (it exports the data to look exactly like the datagridview) but its painfully slow. It exports something in the region of 100 records per minute. Most of the time, the datagridview can contain anywhere from 3000-32,000 records. As such, at 100 records per minute, the excel generation can take updwards of 50minutes. Unacceptably slow for the purposes of the program.
What do people recommend as the best method to quickly dump the contents of a datagrid into excel. By quickly, im talking at the speed of about 10,000 records per minute. In all honesty, anything over 5000 records per minute will be fast enough, but the quicker the better!
Is there a way of creating a new dataset.datatable that is built of the contents of the datagridview and then building an excel sheet by connecting to the new dataset?
I would like to be able to export to Excel 2000-2003 at a minimum, but if i can do excel 97 as well it won't hurt.
