SelectionChangedEventArgs.InvokeEventHandler Method

Performs the proper type casting to call the type-safe SelectionChangedEventHandler delegate for the SelectionChanged event.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)
abstract InvokeEventHandler : 
        genericHandler:Delegate * 
        genericTarget:Object -> unit  
override InvokeEventHandler : 
        genericHandler:Delegate * 
        genericTarget:Object -> unit

Parameters

genericHandler
Type: System.Delegate

The handler to invoke.

genericTarget
Type: System.Object

The current object along the event's route.

The following example creates a ListBox and subscribes to the SelectionChanged event. It uses the SelectionChangedEventArgs to find the selected item in the ListBox.

      <WrapPanel Width="500" Orientation="Horizontal" Name="rectanglesPanel">
        <WrapPanel.Resources>
          <Style TargetType="Rectangle">
            <Setter Property="Height" Value="20"/>
            <Setter Property="Width" Value="20"/>
            <Setter Property="Margin" Value="5"/>
          </Style>
        </WrapPanel.Resources>
      </WrapPanel>

      <ListBox Name="myListBox" HorizontalAlignment="Left" SelectionMode="Extended" 
            Width="265" Height="55" Background="HoneyDew" SelectionChanged="myListBox_SelectionChanged"
            ItemsSource="{Binding Source={StaticResource Colors}}" IsSynchronizedWithCurrentItem="true">
      </ListBox>
