当单击插入按钮（btnSinifEkle）时，我的事件通过 OnBeforeRecordInserted="tetikle4" 触发。即使我单击取消按钮，它已经通过 OnBeforeRecordInserted 插入并显示在网格内。我怎样才能避免这种情况。另外，当我单击插入按钮时，记录显示在网格内，即使我不告诉更新或取消。

太感谢了。

商店的 OnBeforeRecordInserted 在这里被调用：

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）。
