3.somthing else that close to this things...(query dataset with no

you cant query a dataset. All u can do is manipulate the records in the datatables.

Hi,

Yes you can do all the things you have asked.

The DataTable has a method called select which takes the query and returns a DataRow() array of the rows that pass the query from the given datatable. So you can create a table with these rows and add this table to the dataset if you need.


Cheers.
