PowerBuilder PowerScript从下拉列表中选择多个选项

标签： powerbuilder

我在解决这个概念时遇到了很大的困难：我们目前在订单屏幕上显示我们的销售代表下拉菜单，根据添加到订单中的产品，它们将显示多个附加选项在之前的行。问题在于他们只能选择其中一个选项，并且订单项会写入订单，然后代表无法选择第二个加载项添加到订单中（如果客户想要同时添加 - 而不是一个）。下面发布的代码是我之前的程序员的工作，所以我不确定它是否写得好，因为Powerscript对我来说是新的。

警告 - 这必须保持下拉列表，我不能简单地在后台添加第二个附加组件。为了使订单系统正常工作，选定的插件必须紧接主产品之后，一个接一个。我也无法添加“捆绑”产品，因为这会混淆销售报告。

经过多次头痛和重写代码后，我能够创建一个SQL产品，我认为它是两个附加产品的捆绑包，并使用PowerBuilder中的代码检查这些捆绑产品，然后插入单独的行项目每。我做了一些硬编码，因为它需要尽快完成，所以如果有人对更漂亮，更有效的非硬编码脚本有任何想法，请告诉我。

所有更改都发生在itemchanged()事件中：
