At the moment the ListView gets my data - however, I want to show the data in both columns. Right now it simply displays both column values vertically.

public void PopulateListView(DataCollection<Entity> items)
        {

            CompanyList1.Width = 450;
            CompanyList1.Height = 100;
            CompanyList1.Location = new System.Drawing.Point(10, 10);
  
            ColumnHeader header1, header2;
            header1 = new ColumnHeader();
            header2 = new ColumnHeader();

            header1.Text = "Company Name";
            header1.TextAlign = HorizontalAlignment.Left;
            header1.Width = 70;

            header2.TextAlign = HorizontalAlignment.Left;
            header2.Text = "Primary Role";
            header2.Width = 200;


            CompanyList1.Columns.Add(header1);
            CompanyList1.Columns.Add(header2);

      
            CompanyList1.View = View.Details;
         

            foreach (Entity i in items)
            {
                if (i.Attributes.Contains("new_primaryroleid"))
                {
                    EntityReference role = (EntityReference)i.Attributes["new_primaryroleid"];
                    CompanyList1.Items.Add(i.Attributes["name"].ToString());
                    CompanyList1.Items.Add(role.Name);
                }
                else
                {
                    CompanyList.Items.Add(i.Attributes["name"]);
                }
            }

        }
