从 JQuery 选中/取消选中后，RadioListButton 选择无法正常工作

如何解决从 JQuery 选中/取消选中后，RadioListButton 选择无法正常工作

我有一个 radiobuttonList，它有三个选项，值为 1、2、3，用户不能取消选择。我添加了一些 jquery 来检查/取消选中选择，但它无法正常工作。 根据代码，新的 radiolist 控件被创建，无论它在 DB 中有什么值，它都会选择它并使该选择 = true。现在，当我切换选中/取消选中并保存页面重新加载并再次调用 createchildcontrol 并设置来自 db 的先前值并且 selectedvalue 显示为 prev 值时，它没有将 selectedvalue 显示为 null。

控件代码如下
