Question

当点击插入按钮（btnSinifEkle）时，我的事件通过OnBeforeRecordInserted =“tetikle4”触发。甚至我点击取消按钮，它已经通过OnBeforeRecordInserted插入并显示在网格内。我怎么能避免这个。当我点击插入按钮，记录显示在网格内，甚至我不告诉更新或取消。

非常感谢你。

此处调用商店的OnBeforeRecordInserted：

grid.store.insert(0, r);

因为您设置了AutoSync =“true”。

为避免这种情况，您应该设置AutoSync =“false”并在需要时调用Store的同步方法（客户端）。
