Updating database with datagrid

Rated 3.81/5 based on 563 customer reviews

I have a Data Grid View that is attached to a Binding Source that gets data from a SQL Server database.I can populate the Data Grid View without a problem.When Update is called, the Data Adapter will attempt to execute each query (UPDATE, INSERT, DELETE) on every row of the Data Set that has been updated, inserted, and deleted.For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.
