wpf Load

第一种写法，写在Interaction.Triggers

<UserControl>

 <b:Interaction.Triggers>
        <b:EventTrigger EventName="Loaded">
            <b:CallMethodAction TargetObject="{Binding}"
                                MethodName="Load" />
        </b:EventTrigger>
    </b:Interaction.Triggers>

</UserControl>

第二种写法，直接写在UserControl的Loaded事件中

<UserControl x:Class="ChuckReviewView"
             xmlns:viewmodels="Chuck.ViewModels"
             d:DataContext="{d:DesignInstance Type=viewmodels:ChuckReviewViewModel}"
             mc:Ignorable="d"
             Loaded="{DXEvent Handler='Load()', CatchExceptions=False}">
</UserControl>

IsBusy的加载圈

<dx:LoadingDecorator IsSplashScreenShown="{Binding IsBusy}">
