问题 I’m learning C# and building a UI that reads and writes integers to an XML config file. The UI uses a variety of custom user controls. I have a 3 radiobutton user control that binds to a single int variable (control returns 0,1,2). The control uses an event to trigger the update. It looks at the 3 isChecked properties to determine the new int value. But I don’t know how to update the original binding value from the code behind. It's once removed so to speak because there are two binds..one in
