WPF中添加Event
1. ListBox中添加Event
<ListBox x:Name="itemsControl" BorderThickness="0" ContextMenuService.IsEnabled="{Binding IsContextMenuOpen,UpdateSourceTrigger=PropertyChanged,Mode=TwoWay}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" Focusable="True" ItemsSource="{Binding MyCollection}" Style="{StaticResource EquipmentListStyle}" HorizontalAlignment="Stretch" Background="WhiteSmoke" SelectionMode="Single" PreviewMouseLeftButtonDown="itemsControl_PreviewMouseLeftButtonDown" ContextMenuOpening="itemsControl_ContextMenuOpening"> <ListBox.Resources> <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> <Setter Property="VerticalContentAlignment" Value="Top"/> <Setter Property="Focusable" Value="True"></Setter> <Setter Property="ContextMenu" Value="{StaticResource PanelContextMenu}"/> <EventSetter Event="LostFocus" Handler="ListBoxItem_LostFocus"/> <EventSetter Event="LostKeyboardFocus" Handler="ListBoxItem_LostKeyboardFocus"/> </Style> </ListBox.Resources> </ListBox>
code behind 代码
private void ListBoxItem_LostFocus(object sender, RoutedEventArgs e) { //((SolidColorBrush)(sender as ListBoxItem).Resources["SelectionColorKey"]).Color = Colors.Transparent; } private void ListBoxItem_LostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e) { //ListBoxItem lbi = sender as ListBoxItem; //if (lbi != null) //{ // ((SolidColorBrush)lbi.Resources["SelectionColorKey"]).Color = Colors.Transparent; //} //((SolidColorBrush)(sender as ListBoxItem).Resources["SelectionColorKey"]).Color = Colors.Transparent; }
显示Menu
<ContextMenu x:Key="MyContextMenu" StaysOpen="False" Opened="MyContextMenu_Opened"> <MenuItem x:Name="menuItemEdit" Header="Edit" Click="ContextMenu_Edit_Click"> </MenuItem> <MenuItem x:Name="menuItemTest" Header="Test" Click="ContextMenu_Test_Click"> </MenuItem> </ContextMenu>
Menu event code behind
private void ContextMenu_Edit_Click(object sender, RoutedEventArgs e) { }
