using linq select with on a partial class

Hello;

I am using a linq statement to populate a datagrid as follows:

 Dim packages = From p In db.Packages _
                       Join d In db.details On p.PackageID Equals (d.MainID) _
                       Where p.statuscode = 1 And (d.InboundDate = datePicker.Value) And d.RecordType = 11 _
                       Select New OMGridData With {.name = d.ConsigneeName}

        PackagesDataView.DataSource = packages

Select allOpen in new window

I have named the columes using the dataPropertyName.

This works perfectly, I have created a test class OMGridData that has only one member.

However, instead of creating an entirely new class for this I would like to use a existing class: detailReportClass

detailReportClass has all the members I need and then some - that is the problem, it is creating a colume for every one of them.

How do I limit it?

In other words :

   Dim packages = From p In db.Packages _
                       Join d In db.details On p.PackageID Equals (d.MainID) _
                       Where p.statuscode = 1 And (d.InboundDate = datePicker.Value) And d.RecordType = 11 _
                       Select New detailReportClass With {.Consignee = d.ConsigneeName, .city = d.City}

Select allOpen in new window

Creates about 15 columes in my datagrid instead of just the two I want.

Any help would be great - I do this a lot and would rather now create redundant classes.

Thank you!
