List数据绑定

通常状况集合的数据绑定都是用ObservableCollection，但今天使用List作数据绑定，发现一个奇怪的问题。

描述：

List的数据当在插件加载的时候进行数据初始化（经过Add方法），发现界面展现不出来，数据没有绑定上，当把数据初始化放在构造函数中，就可以正常。

解决：

缘由是List在插件加载的时候已经将数据进行绑定了，此时在经过Add是通知不到的，只有借助中间变量，一次性赋值：

//old-这样处理不正确
GroupFieldSrc.Add(new NameValue { IsSelected = true, Value = "branch_no", Name = "业务部门" });
GroupFieldSrc.Add(new NameValue { IsSelected = true, Value = "trader_id", Name = "交易员" });
GroupFieldSrc.Add(new NameValue { IsSelected = true, Value = "operator_no", Name = "下单员" });
GroupFieldSrc.Add(new NameValue { IsSelected = true, Value = "prod_account", Name = "项目" });
GroupFieldSrc.Add(new NameValue { IsSelected = true, Value = "fund_account", Name = "资金帐号" });
GroupFieldSrc.Add(new NameValue { IsSelected = true, Value = "contract_code", Name = "合约代码" });
GroupFieldSrc.Add(new NameValue { IsSelected = true, Value = "entrust_bs", Name = "买卖方向" });
GroupFieldSrc.Add(new NameValue { IsSelected = true, Value = "offset_direction", Name = "开平仓方向" });
//处理方式
List<NameValue>GroupFieldSrc1 = new List<NameValue>();
GroupFieldSrc1.Add(new NameValue { IsSelected = true, Value = "branch_no", Name = "业务部门" });
GroupFieldSrc1.Add(new NameValue { IsSelected = true, Value = "trader_id", Name = "交易员" });
GroupFieldSrc1.Add(new NameValue { IsSelected = true, Value = "operator_no", Name = "下单员" });
GroupFieldSrc1.Add(new NameValue { IsSelected = true, Value = "prod_account", Name = "项目" });
GroupFieldSrc1.Add(new NameValue { IsSelected = true, Value = "fund_account", Name = "资金帐号" });
GroupFieldSrc1.Add(new NameValue { IsSelected = true, Value = "contract_code", Name = "合约代码" });
GroupFieldSrc1.Add(new NameValue { IsSelected = true, Value = "entrust_bs", Name = "买卖方向" });
GroupFieldSrc1.Add(new NameValue { IsSelected = true, Value = "offset_direction", Name = "开平仓方向" });
GroupFieldSrc = GroupFieldSrc1;

这里建议使用ObservableCollection
