如何在 {s：GridColumn s：itemEditor fx：Component s：ComboBoxGridItemEditor s：dataProvider＆gt;]}
更新单元格后，在文本框中获取Datagrid Cell的值这里我使用Webservice来获取 datagrid 中的数据，现在我想更新我的最后一个GridView列。在项目编辑器中，点击时，我会从下拉列表中获取下拉列表 ComboboxGridItemEditor和Array List作为此列的Dataprovider 。我想在更改时更新文本框中的值。
您会看到我在我的应用程序中使用的示例。

我建议根据AsyncListView创建自己的类，然后重写方法itemUpdated。从那里，您可以调度自定义Event以将更改传播到其他UI组件。
