The DataView provides different views of the data stored in a DataTable. That is we can customize the views of data from a DataTable. Changes made to a DataView affect the underlying DataTable automatically, and changes made to the underlying DataTable automatically affect any DataView objects that are viewing that DataTable. We can create a new DataTable from the DataView . We can use the ToTable method to copy all the rows and columns, or a subset of the data into a new DataTable.
