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>
