RE: Explain about rowstate in a dataset table?
|
contd...
A newly created DataRow has its RowState set to Detached until it is added to the DataRowCollection via the DataRowcollection::Add method.
The RowState is initialized to Added until the DataRow::AcceptChanges method is called, at which point the RowState becomes Unchanged.
If you call DataRow::Delete, the row's RowState becomes Deleted, and subsequently calling DataRow Collection::Remove (or DataRowCollection::RemoveAt) will not affect its RowState. The opposite is also true: Removing a DataRow from a Data RowCollection sets the row's RowState to Detached, but subsequently deleting it will not alter its RowState value. |
