How to export the gridview data in dbf file Format?

[ABC]

Export excel is OK,but how to export other format?

[Eric]

What type of DBF file are you after? There are a lot of variations. I would look into exporting to a CSV and then converting to the required file format.

What I want is  the file extensions called dbf,like *.dbf

All use the dbf file extension:
FoxBASE , FoxBASE+/Dbase III plus,
Visual FoxPro
dBASE IV
dBASE IV with memo
FoxPro 2.x (or earlier) with memo
HiPer-Six format with SMT memo file


Edit: Merged some database types.
