Your current code is creating a new Window instance.您当前的代码正在创建一个新的 Window 实例。 If you want to get the Window containing the UC you can call Window.GetWindow and then cast to your specific Window type:
如果您想获得包含 UC 的 Window ,您可以调用 Window.GetWindow ,然后转换为您的特定 Window 类型:
private void btnNext_Click(object sender, RoutedEventArgs e)
{
var gt = Window.GetWindow(this) as GetStarted;
if (gt != null)
{
gt.image0.Visibility = Visibility.Visible;
gt.lblSteps.Content = "Step 2 of 5";
}
}
