情况一：普通按钮单击事件
< Button Content ="Button1" Command =" {Binding CommandSave} " IsEnabled =" {Binding IsEnableSave,Mode=TwoWay} " Margin ="10,0,0,0" Width ="60" Height ="23" VerticalContentAlignment ="Center" HorizontalContentAlignment ="Center" />情况二：特殊事件处理(使用System.Windows.Interactivity处理)
引入命名空间：
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"< TextBox x:Name ="TextBox1" Grid.Column ="0" Grid.Row ="0" HorizontalAlignment ="Left" VerticalAlignment ="Center" Margin ="0,0,0,0" Width ="160" Height ="23" > < i:Interaction.Triggers > < i:EventTrigger EventName ="TextChanged" > < i:InvokeCommandAction Command =" {Binding CommandPageIndexChanged} " CommandParameter =" {Binding ElementName=ss,Path=Text} " /> </ i:EventTrigger > </ i:Interaction.Triggers > </ TextBox >
情况三：绑定键盘事件（求最优解决方案）
方案一：只能借用CodeBehind来调用ViewModel的Command
< TextBox x:Name ="TextBox1" Grid.Column ="0" Grid.Row ="0" KeyDown ="txtFFaraCode_KeyDown_1" />void txtFFaraCode_KeyDown( object sender, KeyEventArgs e) { if (e.Key ==Key.Enter) { ViewModels.QuoteWinNewVM vm = (ViewModels.QuoteWinNewVM) this.DataContext; vm.CommandFaraCodeKeyDown.Execute(); } }
方案二：用KeyTrigger最好了，然后在ViewModel实现Command 此方法测试失败，求解决方案
< TextBox x:Name ="TextBox1" > < i:Interaction.Triggers > < input:KeyTrigger Key ="Enter" FiredOn ="KeyUp" > < i:InvokeCommandAction Command =" {Binding CommandFaraCodeKeyDown} " CommandParameter =" {Binding ElementName=ss,Path=Text} " /> </ input:KeyTrigger > </ i:Interaction.Triggers > </ TextBox >
