kendo-grid - Kendo UI JQuery - 网格一键触发多个“读取”、“创建”、“更新”和“销毁”操作

Question

1. 当我使用“kendo.data.GanttDataSource”时，网格会从控制器触发所有“读取”、“创建”、“更新”和“销毁”操作方法：但当我使用“kendo.data.DataSource”时，只有网格触发“读取”。
2. 当我点击“添加新记录”按钮时，会触发一个相应的创建操作方法（成功）但也会触发多个失败的更新操作方法（这些触发的数量等于网格中的行数。内部服务器错误（ 500）为每个调用返回）
3. 当我点击删除时，会为所有记录触发删除操作方法，从而使我的网格为空。
