我需要知道如何获得每种选定药物的类别。谢谢您可以将
单选按钮的IsChecked
属性绑定到数据类的源属性:
这是更好的解决方案
最快的方法可能是在可视树中找到所选的单选按钮

ListBoxItem lbi = listBoxItems.ItemContainerGenerator.ContainerFromItem(items) as ListBoxItem;
if (lbi != null)

{
MessageBox.Show("selected: " + rb.Content.ToString());

您已经在使用一些绑定。为什么不绑定单选按钮呢?然后在viewmodels中有了这些值。您已经使用了一些绑定。为什么不绑定单选按钮呢?然后在viewmodels中有这些值。
