WPF从DataTrigger设置Image.Source [英] WPF Setting Image.Source from DataTrigger

问题描述

我正在尝试为 Image 元素定义 DataTrigger ，以便显示已连接/已断开连接的图像。我一直收到无效的PropertyDescriptor 消息。有什么想法吗？

I'm trying to define a DataTrigger for an Image element so that it shows a connected/disconnected image. I keep getting an Invalid PropertyDescriptor message. Any ideas?

<Image>
    <Image.Style>
      <Style>
        <Style.Triggers>
          <DataTrigger Binding="{Binding Source={x:Static my:Server.Instance}, Path=Connected, Mode=OneWay}"
                       Value="True">
            <Setter Property="Source"
                    Value="serverconnected.png"/>
          </DataTrigger>

        </Style.Triggers>
      </Style>
    </Image.Style>
</Image>
