推荐答案

ItemRenderer用于配置列表控件中外观的外观(即，图片+文本可能是ItemRenderer的用例) ).因此是渲染"，它将如何显示(只读).

ItemRenderer is for configuring how something will look in a list control (i.e. a Picture + text might be a use case for an ItemRenderer). Thus "Render", how it will display (read-only).

ItemEditor用于当您要覆盖用户可能如何更改列表中的值时(假设您已将所讨论控件上的所有必需可编辑属性设置为允许编辑).一个很好的例子是日期列.也许您希望DataGrid在列表中将日期显示为12/28/2009，但是当用户单击它时，他们将获得一个DateChooser控件来设置新日期.

ItemEditor is used when you want to override how the user might change the value in the list (assuming that you've set all the requisite editable properties on the controls in question to allow edits). A good example could be a date column. Perhaps you want a DataGrid to show a date as 12/28/2009 in the list, but when the user clicks on it, they get a DateChooser control to set a new date.
