You told me mmBusinessObject.DataRow contains the current datarow being edited on the form. When I try to set a value into one of the field, I got "Object reference not defined" error. I created my own method in my BusinessObject override to handle that now:

public DataRow GetCurrentDataRow()
{
	return this.GetCurrentDataSet().Tables[0].Rows[0];
}

This function works but I prefer to use your property.
