使用bindingsource填充组合框

Question

Windows上的

形成所有文本框，组合框从acctPackageBindingSource绑定。我在组合框中进行双击而只显示int值的问题意味着它来自acctPackage。我想显示名称意味着该值的“显示成员”。那个来自不同表名的是sysCode。那么如何才能完美展示显示器成员呢？以下是我的代码

 // Here the all value is coming form Syscode table .

  public void FillDropDown()
    {
        if (_commonComponent == null)
            _commonComponent = new CommonComponent();

        List<SysCode> _syscode = _commonComponent.GetByTableCodeForIncomeDedMapping("19");
        bindingSourceSysCode.DataSource = _syscode;

        packageCodeComboBox.DataSource = bindingSourceSysCode;
        packageCodeComboBox.DisplayMember = "Desclong2";
        packageCodeComboBox.ValueMember = "PackageCode";

    }



//This part is bind my all value on the form 

  private void FillAcctPackage()
    {
        if (_commonComponent == null)
            _commonComponent = new CommonComponent();

        acctPackageBindingSource.DataSource = _commonComponent.GetAcctPackge();



    }
