Wpf数据模板
我已经为ListView定义了一个DataTemplate来显示fileInfo详细信息。 这是数据模板Wpf数据模板,wpf,datatemplate,Wpf,Datatemplate,我已经为ListView定义了一个DataTemplate来显示fileInfo详细信息。 这是数据模板 <DataTemplate x:Key="srchFileListTemplate"> <StackPanel> <WrapPanel> <TextBlock FontWeight="Bold" FontFamily="Century Gothic" Text="File

List视图的ImagesSource
是List
我必须根据列表中文件的扩展名添加自定义图标。是否可以将扩展传递给方法以获取现有DataTemplate中的图标路径?您需要一个转换器:
[ValueConversion(typeof(string), typeof(ImageSource))]
public class FileIconConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
string fileName = value as string;
if (fileName == null)
return null;
return IconFromFile(fileName);
}
private ImageSource IconFromFile(string fileName)
{
// logic to get the icon based on the filename
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
// The opposite conversion doesn't make sense...
throw new NotImplementedException();
}
}
然后需要在参考资料中声明转换器的实例:
<Window.Resources>
<local:FileIconConverter x:Key="iconConverter" />
</Window.Resources>
您可以在绑定中使用它,如下所示:
<Image Source="{Binding FullName, Converter={StaticResource iconConverter}}" />
我遇到的问题是图像源不是静态的,我必须根据扩展名获取图像源,并且必须将图像包含在ListView的数据模板中我不理解您的评论。。。“在数据模板中包含图像”是什么意思?
