You can easily update a database from a Data Grid View. Step 4See the properties of the Adapter on Data Set, whether it has a query for updating or not. Step 5A line is automatically generated, when you bind the Data Grid View to the dataset.

For example, you might inadvertently write data of the wrong type to a column, or data that's too long, or data that has some other integrity problem.

All your insertions, updates, and deletions will be effected by the single button.

When you data bind dataset tables to controls on a Windows Form or XAML page, the data binding architecture does all the work for you.

Information about the changes in a dataset is maintained in two ways: by flagging rows that indicate that they have changed (Row State), and by keeping multiple copies of a record (Data Row Version).

By using this information, processes can determine what has changed in the dataset and can send appropriate updates to the data source.

If you aren't using data binding, and are saving changes for related tables, you have to manually instantiate a variable of the auto-generated dataset).
