我正在使用 SmartGWT 2.5，特别是由 RESTDataSource 支持的 ListGrid。
服务器集成是通过servlet的方式实现的，我只需要实现fetchData()。数据是在服务器端填充的 List>，转换为 JSON 并在 DSResponse 中发送。数据源支持的实时网格通过 grid.fetchData() 以编程方式触发服务器获取。
要求：
我希望根据我从服务器发送的记录属性之一的值设置记录基本样式（或自定义样式）。
为了做到这一点，我尝试了 DataArrivedHandler，在其中迭代可用行，使用行号从网格获取 ListGridRecord，并使用 gridRecord.set_baseStyle(String stylename) 或 gridRecord.setCustomStyle(String stylename) 来尝试并为该记录应用灰色的 CSS。之后，我调用 grid.markForRedraw()，但没有效果。 CSS 不会被应用。
我必须提到，我已经使用相同的 css 非常成功地将普通 listGrid（无数据源）上的行变灰。
问题：
我的策略正确吗？
是否有另一种方法可以根据属性值将样式应用于记录。
I am using SmartGWT 2.5, specifically a ListGrid backed by a RESTDataSource.
The Server integration is achieved by way of a servlet, and I only need to implement fetchData(). The data is a List<Map<String, Object>> populated on the server side, converted into JSON and sent in the DSResponse. The Live grid backed by the datasource triggers a server fetch programmatically by way of grid.fetchData().
Requirement:
I wish to set a record base style (or custom style) based on the value of one of the record's attributes, which I send over from the server.
In order to do this, I have tried a DataArrivedHandler, where I iterate over the available rows, get the ListGridRecord from the grid using the row number, and use gridRecord.set_baseStyle(String stylename) or gridRecord.setCustomStyle(String stylename) to try and apply a greyed out css for that record. After this, I call grid.markForRedraw(), however to no effect. The CSS does not get applied.
I must mention that I have used the same css to grey out rows on a normal listGrid (no dataSource) very successfully.
Questions:
Is my strategy the right one?
Is there an alternative method to apply a style to a record based on an attribute value.

您的策略是正确的，我已经在我的代码中成功实现了您所需的功能。确保您正确获取记录并且其中存在测试属性。我建议使用 JSON.encode(record.getJsObj()) 来查看您的记录实际填充的内容。无需显式调用 markForRedraw()，因为在 DataArrivedEvent 触发后，ListGrid 将重绘其视图。如果您需要更多帮助，请发布一个小代码片段。另外，正如阿兰的评论所建议的，亮点可能是另一个不错的选择。
Your strategy is correct and I have successfully achieved your required functionality in code of mine. Make sure you are correctly getting the record and that the test attribute is present in it. I suggest a JSON.encode(record.getJsObj()) to see what your record actually is filled with. No need for markForRedraw() explicit call, as after the DataArrivedEvent has fired the ListGrid will redraw its view. Post a small code snippet if you need more help. Also as suggested from the comment from Alain, highlights might be another good option to look at.
