我似乎无法成功调用从按钮事件单击启动用户控件的方法。 当我从其他地方调用相同的方法时它工作正常。 这是方法:
private void StartWaitCircle()
{
WaitCircle waitCircle = new WaitCircle();
circle.Children.Add(waitCircle);
waitCircle.IsEnabled = true;
waitCircle.HorizontalAlignment = System.Windows.HorizontalAlignment.Center;
waitCircle.VerticalAlignment = System.Windows.VerticalAlignment.Center;
waitCircle.Visibility = System.Windows.Visibility.Visible;
waitCircle.Focus();
}
当我这样做时:
private void button_Click(object sender, RoutedEventArgs e)
{
StartWaitCircle()
}
上面的代码调用了该方法,但没有任何反应。
