I have an aspx page that retrieves data from several different sources and uses them to define a new GridView, which is the exported as an Excel file.
I originally had all of the code required in a single Page_Load sub. Once I worked out all of the standard problems that seem to trouble those of us trying to export to Excel, it was working fine. But now I need to make it so that it exports exports the GridView as an Excel file upon clicking a button. "Easy enough," I thought, "I'll just cut and paste that part of the code into a Button_Click sub." It's not working out at all though.
The Excel file it produces when I click the button is only 17 bytes long. It consists of <div> in cell A1 and </div> in cell A3 and nothing else. I've tried a hundred things but I can't seem to get this to work. I'm still somewhat new to ASP, so it may well be something simple and obvious I just don't know about. Any suggestions?
Thanks much.

Hi, I have a webpage that is taking input from a form and using it as
criteria to select data out of an sql database. The page displays an
html table with the results. The user can then click a button "excel"
to open or save the file as an excel document. This works, and
everything in the excel document is formatted fine except for the
first column which in this case is "Part Number". The problem is that

I am exporting data from an EDITABLE DATA GRID EXCEL. But the 1st column
in data grid is Edit Column. I want to display all columns in Excel except

Hi, I have kind of a strange problem. I have a report that I need to export to excel.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
