Silverlight控件未加载

Question

I'm working on a Silverlight 3.0 app, and about 1 out of every 10 or 20 times, a UserControl I've created won't load with the rest of the application. The rest of the application loads and functions correctly. So far, I've been exclusively launching this from visual studio, but I'd like to be sure that this isn't something that will happen when it's actually deployed.

Does anyone know what might be causing this? Has anyone else experienced this?

EDIT: the control's constructor (all animations are initialized)

        InitializeComponent();

        m_CenterXAnimation.Duration = new TimeSpan(0, 0, 0, 0, 800);
        m_CenterYAnimation.Duration = new TimeSpan(0, 0, 0, 0, 800);

        m_FadeOutAnimation.Duration = new TimeSpan(0, 0, 5);
        m_FadeInAnimation.Duration = new TimeSpan(0, 0, 5);
        m_FadeOutAnimation.To = 0;
        m_FadeInAnimation.To = 1;

        m_ScaleDownAnimation.Duration = new TimeSpan(0, 0, 0, 0, 800);
        m_ScaleUpAnimation.Duration = new TimeSpan(0, 0, 0, 0, 800);
        m_ScaleDownAnimation.To = 1;
        m_ScaleUpAnimation.To = 1.1;   

        App.Current.Host.Content.Resized += new EventHandler(Content_Resized);

Answer 1

It sounds to me like you getting an exception within your UserControl that is not causing a full crash but is preventing your control from completing initialization. You could try debugging the initialization of the UserControl and it's bindings - start by placing a breakpoint in the unhandled exception handler of your App class.

I doubt the problem is with the UserControl. Sounds a like a timing issue. I've had similar problems but it was caused by other parts of the application - usually in the order events fire. Nothing wrong with your example code - the issue lies elsewhere.
