I am using SpreadsheetGear 2012 in my application to load, modify then save a new copy of a template workbook.
My code takes invoicing information from a database and formats it for the workbook. Then the user will print an invoice from the formatted information using a button on the workbook.
I use a template workbook with some formatting already provided to make my life easier. Included on the original template workbook is a button that runs a VBA macro in the spreadsheet. The VBA macro loads successfully but the button just disappears in the new workbook.
Some of the steps I have tried to rectify the issue: I've added a new button, changed the VBA macro code from a function to a sub, saved the template file as a macro-enabled spreadsheet (.xlsm) and saved the revised copy as a macro-enabled spreadsheet file.
Has anyone experienced this issue and do you have a solution?
If you are using the Open XML file formats (XLSX/XLSM), then this is a known limitation:
http://www.spreadsheetgear.com/support/help/spreadsheetgear.net.7.0/#SpreadsheetGear_2012_Limitations.html
In short, SpreadsheetGear 2012 does not support reading/writing Form Controls (like buttons), as well as Cell Comments, when working with the Open XML file formats. So your button is getting dropped when the file is initially read into SpreadsheetGear.
If you want to preserve these objects through SpreadsheetGear, you will need to use the XLS (FileFormat.Excel8) file format, which does support them.
I have been looking for a solution all over the last days and I found that this library EPPlus allows retrieving in the same time formatting besides the actual data, plus charts, if needed, from Excel files which is what I am aiming at the moment.
Could you please explain to me step by step how to read a Range of cells from an Excel (like A1:P34) file that resides at a certain path, via ASP.NET/C#?
PATH would be something like //ServerName/Folder1/Folder2/Folder3/ExcelFileName.xlsx
I looked over the web, but there is not explicit documentation for my level of C# expertise on this. I tried several examples but none displayed the Excel Range into the webpage. (e.g this one.)
Note: the three examples I have tried all included an File Upload Control, I do not need such. I want to read the Excel file from a specified location over the local network.
EPPlus library is available here.
If you can recommend me any simpler resources to understand EPPlus on:
-reading from Excel
-writing from Excel
-reading charts from Excel
This EPPlus does seem wonderful in its functionality.
To read a file off the server take a look at this:
Open ExcelPackage Object with Excel application without saving it on local file path
Just need to set the var path part for your file.
To actually put the excel data on a web page, that is not so easy. See this:

Response to Comment:
Hosting an actual excel sheet in web page is temperamental at best but there are ways to do it (I haven't tried it personally). SharePoint is probably your best option if you have it available. If not, you would have to use an iFrame or some kind of office web component. Check this out:
how to display excel sheet in html page
i have a problem, i need to show a group of excel files in some views of an mvc4 project. The real problem is that the files are Excel PowerPivot and they can not be shown as images or pdf, it has to be Excel files.
Any ideas?
Thanks for the help...
If you can open the workbook in the Browser-based version of excel and see what you need to display, you can then use the Share->Embed feature of the Excel online app to generate HTML or JavaScript embed code.
If you need to have the end user manipulate the workbook to retrieve the necessary data from the PowerPivot table, then they'd most likely be better off downloading the workbook and going from that.
If they don't need to manipulate anything, look into if you can export the workbook to HTML in some fashion and embed that.
Hopefully that might put you down the right track.
i have a requirement to open a blank excel file on a click of button in front of the user with predefined headers. and user will fill the data's and upload that excel file then i will read that and update my database. My 1st concern is how to open that blank sheet in front of the user..
anyone pls help i really need this
If your column headers are fixed then go with Excel Template. Create Excel template and open it with Process.Start("")
Create an excel file with the template of your choice
place the file inside a directory of your website.
Create link on a page to the file
