Export DataSet to a .csv file

[snufse]

Is there an easy way to export a data set to a csv file or do I have to map each element? I read something like this:

<pnwc:ExportButton 
id="btnExcel" 
runat="server" 
Separator="TAB" 
Text="Export to Excel" 
FileNameToExport="Books.xls" BackColor="#E0E0E0">
</pnwc:ExportButton>

but it tells me that the tag is invalid.

The pnwc prefix indicates that it's a custom third party control which you most likely don't have. You'll need to export your data using your own code.
