推荐答案
如果您使用 recreateForm:true 选项，则每次用户打开表单时都会重新创建编辑表单.因此，选择将填充"SalesDropDownGrid.php"(来自editoptions.dataUrl)返回的项目.
If you would use recreateForm: true option of the form editing then the edit form will be recreated every time when the user open the form. So the select will be filled with the items returned by "SalesDropDownGrid.php" (from editoptions.dataUrl).
如果您要在来自"SalesDropDownGrid.php"的响应中设置Cache-Control: max-age=0 HTTP标头，则结果将不会被缓存，并且选择内容将填充为推销员"的当前列表.如果您在PHP代码中设置HTTP标头时遇到问题，可以选择使用
If you would set Cache-Control: max-age=0 HTTP header in the response from "SalesDropDownGrid.php" the results will be not cached and the select will be filled with the current list of "Salesman". If you have some problems with the setting of HTTP headers in your PHP code you can use alternatively
ajaxSelectOptions: { cache: false }
请参见答案.
