다음 예제에서는 ListBox에 Title이라는 제목의 속성이 성공적으로 표시되지만 메서드를 표시 할 방법이 있습니까 GetTitle() 속성에 모든 메서드를 적용 할 필요가 없습니까?메서드를 ListBox의 DataTemplate에 바인딩하는 방법이 있습니까?
이들 중 어느 것도 제대로 작동 :
<TextBlock Text="{Binding GetTitle}"/>
<TextBlock Text="{Binding GetTitle()}"/>
XAML :
<Window x:Class="TestBindMethod8938.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Grid>
<ListBox DockPanel.Dock="Top" ItemsSource="{Binding BackupTasks}" Margin="0 10 0 0">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Title}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Window>
