System.Data Namespace
Represents a customized view of a DataRow exposed as a fully featured Windows Forms control.
Whenever data is displayed ( for example in a DataGrid control ), only one version of each row can be displayed. The displayed row is a DataRowView.
A DataRowView can have one of four different version states: Default, Original, Current, and Proposed.
After invoking BeginEdit on a DataRow, any edited value becomes the Proposed value. Until either CancelEdit or EndEdit is invoked, the row has an Original and a Proposed version. If CancelEdit is invoked, the proposed version is discarded, and the value reverts to the original. If EndEdit is invoked, the DataRowView no longer has a Proposed version; instead, the proposed value becomes the current value. Default values are available only on rows that have columns with default values defined.
