How to create a DataView
The DataView provides different views of the data stored in a DataTable. DataView can be used to sort, filter, and search in a DataTable , additionally we can add new rows and modify the content in a DataTable . DataViews can be created and configured both design time and run time . 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 the DataTable. Using a DataView, you can expose the data in a table with different sort orders, and you can filter the data by row state or based on a filter expression.
We can create DataView in two different ways. We can use the DataView Constructor , or you can create a reference to the DefaultView Property of the DataTable. The DataView constructor can be empty, or it can take either a DataTable as a single argument, or a DataTable along with filter criteria, sort criteria, and a row state filter.
dv = ds.Tables.DefaultView;
