Using the DataRow Property to Access the Current Row

mmBusinessObject has a DataRow property that contains a reference to the "current" DataRow. Depending on the custom code you have created in your business object, you need to check your assumptions to make sure this property truly contains the DataRow you are interested in.

The following mmBusinessObject methods affect the DataRow property:

Method	Effect on DataRow
Cancel(DataSet ds, string tableName)	Sets to null if DataRow.RowState == DataRowState.Detached
Delete(DataRow dr)	Sets to first DataRow in the DataTable
FillDataSet(DataSet ds, string command, string tableName, string databaseKey, CommandType cmdType, params IDbDataParameter[] dataParams	Sets to the first DataRow only when retrieving data into the business object's default DataTable
GetEmptyDataSet(DataSet ds, string tableName, string databaseKey)	Sets to null
LoadRow(object pk)	Sets to the newly loaded DataRow
NavigatedData(DataRowView drView)	Sets to the DataRow just navigated to
NewRow(DataSet ds, string tableName, object defaultValues)	Sets to the new DataRow
ReadXMLFileToDataSet(string xmlFile, DataSet ds	Sets to the first DataRow only when retrieving data into the business object's default DataTable
SaveDataSet(string tableName, int currentRow)	Sets to the DataRow specified in the currentRow parameter
SaveDataView(DataView dv, int currentRow)	Sets to the DataRow specified in the currentRow parameter
SetCurrentDataSet()	Sets to the first DataRow for the default DataTable
