我有一个按钮清除过滤器。我希望在屏幕加载时动态发生按钮单击事件。

    <Button Margin="10,0" commandparameter="Clear_Filter" Command="{Binding ButtonClicks}" >
                <StackPanel Orientation="Vertical">
                    <Image Source="/NextGen.Optik.UI.Presentation;component/Resources/clear_filters.png" Width="32" Height="32" Margin="0,2" />
                    <TextBlock Text="Clear Filters" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </StackPanel>
            </Button>

ViewModel：

      private UICommand _buttonClicks;
    public UICommand ButtonClicks
    {
        get
        {
            return _buttonClicks ?? (_buttonClicks = new UICommand(
                param => ButtonClickCommand(param),param => true
                ));
        }
    }
    public void ButtonClickCommand(object parameter)
    {

        switch (parameter.ToString().ToLower())
        {
            case "clear_filter":
                ClearFilter(); 
        }
    }
