문자열을 아이콘으로 변환하는 데 문제가 있습니다. Geometry 아이콘은 ResourceDictionary에 있습니다. ValueConverter 호출되지 않습니다 (나는 변환기의 변환 방법에서 디버깅을 시도 함).C# WPF 변환기로 바인드 경로 데이터
XAML :
<Window.Resources>
<local:StatusToPathDataConverter x:Key="PathConverter"/>
</Window.Resources>
<Grid>
<Path Width="20"
Height="20"
Stretch="Uniform"
Fill="Black"
Data="{Binding Path=Status,
UpdateSourceTrigger=PropertyChanged,
Converter={StaticResource PathConverter}}"/>
</Grid>
CS :
public partial class MainWindow :Window {
public MainWindow() {
InitializeComponent();
}
public string Status
{
get { return (string)GetValue(StatusProperty); }
set { SetValue(StatusProperty, value); }
}
public static readonly DependencyProperty StatusProperty =
DependencyProperty.Register("Status", typeof(string), typeof(MainWindow));
}
public class StatusToPathDataConverter :IValueConverter {
private static ResourceDictionary iconDictionary;
public ResourceDictionary IconDictionary
{
get
{
if(iconDictionary == null) {
iconDictionary = new ResourceDictionary();
iconDictionary.Source = new Uri("/WPFBindingTest;component/Resources/IconDictionary.xaml", UriKind.RelativeOrAbsolute);
}
return iconDictionary;
}
}
public object Convert(object value, Type targetType, object parameter, CultureInfo culture) {
var status = (string)value;
if(statinStatus == null)
return null;
switch(status.ToLower()) {
case "test":
return IconDictionary["TestIcon"];
// ...
}
return null;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) {
throw new NotImplementedException();
}
}
감사합니다. – MrWoffle
