In these cases the application stays connected to the database system even when it is not using any Database Operations. Net solves this problem by introduces a new component called Dataset. Data Sets only hold data and do not interact with a Data Source.One of the key characteristics of the Data Set is that it has no knowledge of the underlying Data Source that might have been used to populate it.It retrieves data from a database into a dataset and updates the database.When changes are made to the dataset, the changes in the database are actually done by the data adapter. It is a disconnected, cached set of records that are retrieved from a database.

The dataset works as a virtual database containing tables, rows, and columns. Connection String = "Data Source=KABIR-DESKTOP; _ Initial Catalog=test DB; Integrated Security=True" connection. Tables(0) End Sub End Class When the above code is executed and run using Start button available at the Microsoft Visual Studio tool bar, it will show the following window: Clicking the Fill button displays the table on the data grid view control: We have discussed that the Data Set components like Data Table, Data Column and Data Row allow us to create tables, columns and rows, respectively.Introduction This article looks at a neat and not often discussed feature of ADO - disconnected Recordsets.
