WPF usercontrols on separate tabs: why is radiobutton groupname shared between tabs?
问题 I am using a WPF tab control to present separate repeated instances of a user control. i.e. Tab1 for Item1 settings, Tab2 for Item2 settings, and so on. It appears that the radio button group names are being shared between tabs. What is going on? Simple example: A window contains tabs. Each tab contains a user control. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:lib=
