WPF 事件触发命令
方法一使用mvvmlight:
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" xmlns:cmd="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Extras.WPF4" <i:Interaction.Triggers> <i:EventTrigger EventName="Loaded"> <cmd:EventToCommand Command="{Binding HandleCommand}" CommandParameter="LoadItems"/> </i:EventTrigger>
</i:Interaction.Triggers>
方法二：
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" <i:Interaction.Triggers> <i:EventTrigger EventName="Loaded"> <i:InvokeCommandAction Command="{Binding HandleCommand}" CommandParameter="LoadItems" /> </i:EventTrigger> <i:EventTrigger EventName="Unloaded"> <i:InvokeCommandAction Command="{Binding HandleCommand}" CommandParameter="Unload" /> </i:EventTrigger> </i:Interaction.Triggers>
