I would suppose this should be pretty easy, but the cast is not working. The collection members are have null values. How should I get the selected items as anEntityspaces collection  

Code:

if (kgridParts.DataSource != null)
            {
                m_selectedParts = new BusinessObjects.PartCollection();

                foreach (DataGridViewRow row in kgridParts.SelectedRows)
                {
                    BusinessObjects.Part newPart = m_selectedParts.AddNew();
                    newPart = (BusinessObjects.Part)row.DataBoundItem;
                    
                    
                }

                
                this.lbPartVendors.DataSource = m_selectedParts;
                this.lbPartVendors.DisplayMember = "PartName";
                               
            }

Code:

foreach (DataGridViewRow row in kgridParts.SelectedRows)
{
    BusinessObjects.Part newPart = new BusinessObjects.Part();
    newPart = (BusinessObjects.Part)row.DataBoundItem;
    m_selectedParts.AttachEntity(newPart);
}
