WP7图像绑定
我有一个包含列表框的 Windows Phone 7 应用程序。我希望列表框中的每个项目都有一个特定的图像。
<ListBox Height="606" HorizontalAlignment="Left" ScrollViewer.VerticalScrollBarVisibility="Visible"
Margin="20,20,0,0"
Name="listBox1" VerticalAlignment="Top" Width="414" ItemsSource="{Binding SubList, Mode=OneWay}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Height="50" Width="50"
VerticalAlignment="Top" Margin="0,10,8,0" Source="{Binding Image, Mode = OneWay}"/>
<StackPanel Orientation="Vertical">
<HyperlinkButton Content="{Binding Cathegory, Mode=OneWay}" NavigateUri="" HorizontalAlignment="Right">
</HyperlinkButton>
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
与 Image 控件的 Source 属性绑定的属性是一个 Uri。 我的问题是图像没有显示在列表框中。 我尝试使用字符串而不是 Uri,但遇到了同样的问题。
我非常感谢任何帮助:)。
I have a Windows phone 7 application which contains a listbox. I want, for each item in the listbox to have a particular image.
<ListBox Height="606" HorizontalAlignment="Left" ScrollViewer.VerticalScrollBarVisibility="Visible"
Margin="20,20,0,0"
Name="listBox1" VerticalAlignment="Top" Width="414" ItemsSource="{Binding SubList, Mode=OneWay}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Height="50" Width="50"
VerticalAlignment="Top" Margin="0,10,8,0" Source="{Binding Image, Mode = OneWay}"/>
<StackPanel Orientation="Vertical">
<HyperlinkButton Content="{Binding Cathegory, Mode=OneWay}" NavigateUri="" HorizontalAlignment="Right">
</HyperlinkButton>
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
And the property binded to the Source property of the Image control is an Uri.
My problem is that the image is not shown in the listbox.
I have tried using a string instead of the Uri but I get the same issue.
I kindly appreciate any help :).

这应该有效:
This should work:
查看其他 SO 答案,我相信它包含您问题的答案:
图像 UriSource 和数据绑定
但它的基础知识是你需要转换BitmapImage 的 URI/字符串(通过 viewmodel 属性或转换器)
Check out this other SO answer, I believe it contains the answer to your question:
Image UriSource and Data Binding
But the basics of it is that you need to convert your URI/string to a BitmapImage (either via viewmodel property, or converter)
