 private void NameAutoComplete()
    {
        aManager = new InventoryManager();
       // aMember = new Member();

        string[] memberNameFromJoinedDatabase = aManager.GetMemberNameWithDesignamtion(cmbOrgMetroComboBox.ValueMember,Convert.ToInt32(cmbDepartmentMetroComboBox.ValueMember)).Select(x => string.Format("{0} {1}", x.Name, x.MemberDesignation.Name)).ToArray();


        txtNameMetroTextBox.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
        txtNameMetroTextBox.AutoCompleteSource = AutoCompleteSource.CustomSource;

        var autoComplete = new AutoCompleteStringCollection();
        autoComplete.AddRange(memberNameFromJoinedDatabase);
        txtNameMetroTextBox.AutoCompleteCustomSource = autoComplete;
    }
