How to DataAdapter DataGridView - OLEDB
The OleDbDataAdapter plays a vital role in facilitating effective communication between the Dataset and the OLEDB Data Source by utilizing the OleDbConnection Object. The OleDbConnection Object, while responsible for establishing a connection and retrieving data, lacks specific information about the retrieved data. Similarly, the Dataset remains unaware of the Data Source from which the data originates. Consequently, it is the responsibility of the OleDbDataAdapter to seamlessly manage the communication between these two entities. This crucial task is facilitated by the TableMapping Collection.
To ensure a synchronized and coherent workflow, the InsertCommand, UpdateCommand, and DeleteCommand properties of the OleDbDataAdapter object are essential components that enable the database to be updated with the data modifications performed on the DataSet object.
