No Initial Animation

Some developers want to play different animation or no animation the first time Content is set. This may due to loading remote data or just a matter of graphic, animation or interaction design. You could easily achieve that by setting different transition on interrupted or completed. For example you could set the initial duration of a transition to be 0:0:0 like this in XAML:

<telerik:RadTransitionControl x:Name="TransitionControl" 
Duration="0:0:0"         
TransitionStatusChanged="RadTransitionControl_TransitionStatusChanged"> 
    ... 
</telerik:RadTransitionControl> 
And then in code behind set the duration to a reasonable time span after the first content appears:

private void RadTransitionControl_TransitionStatusChanged(object sender, TransitionStatusChangedEventArgs e) 
{ 
    if (e.Status == TransitionStatus.Completed) 
    { 
        this.TransitionControl.Duration = new TimeSpan(0, 0, 1); 
    } 
}
