This exception is thrown if you try to access a DataRow after it has been marked deleted, but before changes have been accepted. Typically, it occurs when you try to retrieve the current value of a deleted row. To prevent this exception, check the DataRow.RowState property before attempting to read the value, and skip the task if the row is in the DataRowState.Deleted state. A related exception that has the same cause is DeletedRowInaccessibleException .
