如何用按钮标记复选框

Question

我有以下场景。我在网格详细信息中创建了一个按钮。在选择记录并单击按钮时，复选框被标记，但我无法将其注册到数据库中。

我已附上 DAC 和图表

你可以帮我解决这个问题，欢迎评论。

提前致谢。

您似乎正在使用按钮的“计算”操作。我看到您在对象 newRowE 上设置值的位置，但您实际上尚未使用该值更新数据库。

最好更新视图，但在这种情况下，直接访问缓存来保存它可能是最简单的，因为它是 DAC 扩展。您需要完成 2 个步骤来更新缓存并保存它。如果您在其他地方执行此操作并且已经通过其他方式（例如用户交互）进行了保存，那么手动保存步骤将是多余的。您可以通过以下 3 种方法执行数据库更新（如果其中一种方案在其他情况下更适合您）。

Base.Caches[typeof(PMBudget)].Update(newRowE);
Base.Save.Press();

-或者-

Base.Caches[typeof(PMBudget)].SetValueExt<PMBudgetExt.UsrMarkforPO>(row, true)
Base.Caches[typeof(PMBudget)].Persist(PXDBOperation.Update);

-或者-

Base.CostBudget.Update(row);
Base.Save.Press();
