I am developing a web application using Isomorphic SmartClient. 我正在使用同构SmartClient开发Web应用程序。 I am searching for a callback fired when the user selects a pick list record from a DynamicForm TextItem pick list, but I am unable to find one. 我正在搜索当用户从DynamicForm TextItem选择列表中选择一个选择列表记录时触发的回调，但是找不到。 Does a callback for this event exist in SmartClient? SmartClient中是否存在此事件的回调？ If not, is there a good way to tell when the user has selected a pick list record? 如果不是，是否有一个很好的方法来告诉用户何时选择了选择列表记录？

Since you are talking about ComboBoxItem probably(and even if it is SelectItem it is the same) and they extends TextItem, which extends FormItem. 由于您可能正在谈论ComboBoxItem（即使它是SelectItem，它也是相同的），并且它们扩展了TextItem，后者扩展了FormItem。 FormItem and it's subclasses do have changed method - http://www.smartclient.com/docs/10.0/a/b/c/go.html#method..FormItem.changed But this one will fire, after change is done, in case you need to handle control on the time of change - use change method (and you can even stop the change by returning false) - http://www.smartclient.com/docs/10.0/a/b/c/go.html#method..FormItem.change FormItem中，它的子类都已经改变了方法- http://www.smartclient.com/docs/10.0/a/b/c/go.html#method..FormItem.changed但是这样一来会火，变更完成后，如果您需要控制更改时间-使用更改方法（甚至可以通过返回false来停止更改） -http://www.smartclient.com/docs/10.0/a/b/c/go .html＃method..FormItem.change
