Hi,

I'm wondering how do you project a TypedList to a custom class/DTO.

The Code I am using are

LkpClassificationTypedList classification = new LkpClassificationTypedList(); adapter.FetchTypedList(classification);

Fields for the Entity are

(LkpClassificationFields.Code, 0, "Code", "", AggregateFunction.None); (LkpClassificationFields.Description, 1, "Description", "", AggregateFunction.None); (LkpClassificationFields.Rate, 2, "Rate", "", AggregateFunction.None); (LkpClassificationFields.Enabled, 3, "Enabled", "", AggregateFunction.None); (LkpClassificationFields.DisplayOrder, 4, "DisplayOrder", "", AggregateFunction.None);

Thanks, Joe

Please try the following:

MyTypedList myTypedList = new MyTypedList();

List<CustomCustomer> customClasses = new List<CustomCustomer>();

DataProjectorToCustomClass<CustomCustomer> projector = 
    new DataProjectorToCustomClass<CustomCustomer>( customClasses );

// Define the projections of the fields.    
List<IDataValueProjector> valueProjectors = new List<IDataValueProjector>();
valueProjectors.Add( new DataValueProjector( "City", 0, typeof( string ) ) );
valueProjectors.Add( new DataValueProjector( "CompanyName", 1, typeof( string ) ) );
valueProjectors.Add( new DataValueProjector( "CustomerID", 2, typeof( string ) ) );
valueProjectors.Add( new DataValueProjector( "Country", 3, typeof( string ) ) );

// perform the fetch combined with the projection.
using( DataAccessAdapter adapter = new DataAccessAdapter() )
{
    adapter.FetchProjection( valueProjectors, projector, myTypedList.GetFieldsInfo(), myTypedList.GetRelationInfo(), 0, true );
}

Where the custom class is:

public class CustomCustomer
{
    #region Class Member Declarations
    private string _customerID, _companyName, _city, _country;
    #endregion

    public CustomCustomer()
    {
        _city = string.Empty;
        _companyName = string.Empty;
        _customerID = string.Empty;
        _country = string.Empty;
    }

    #region Class Property Declarations
    public string CustomerID
    {
        get { return _customerID; }
        set { _customerID = value; }
    }

    public string City
    {
        get { return _city; }
        set { _city = value; }
    }

    public string CompanyName
    {
        get { return _companyName; }
        set { _companyName = value; }
    }

    public string Country
    {
        get { return _country; }
        set { _country = value; }
    }
    #endregion
}

Great, that works fine.

Ive noticed that the DTO task generator only creates DTO's based on entities. Does it also create DTO classes from typedLists?

Does it also create DTO classes from typedLists?

There is no need for that, as TypedLists are actually dataTables.
