Try to google translate if telugu language is available. Another way you can maintain by database for example
suppose datatable has 3 field
1. ID
2. Name
3. Address
you just add more field for telugu language for example
1.ID
2.Name
3.Name_telugu
4.Address
5.Address_telugu
When you bind gridview with telugu language write a qry like
SELECT ID,Name_telugu,Address_telugu from table1
This result just add datasource of gridview then show the gridview content in telugu language.
If you want to back to english same way just change the qry like
SELECT ID, Name, Address from table1
Hope you will get more better solution from codeproject. best of luck
Thanks
