2011年3月15日更新（仍未运作）：对我来说不是很清楚。网格过滤器中的选择数据重新加载（onloadComplete）后不会更新工具栏。怎么了？ 在第一页显示中填充选择。但后来没有。 我在页面网格时是否应该更新？
我的db表中有10000行。 首先，我显示前100行（过滤器选择填充100个值）。 然后我按“页面结束”寻呼机的按钮。数据在网格中重新加载，但过滤器选择不会使用新数据更新。 我怎么能得到希望的结果？
我有一个包含2个jqGrid的页面：master和detail。 两个都有loadComplete事件，在filterToolbars中填充选择。
两个网格中的代码相同。 但问题是我在主网格中有很好的过滤器，在细节网格中没有过滤器。
请查看我的代码。非常感谢。
