绑定元素WPF应用程序

Question

I have this code.

<MediaElement x:Name="VideoControl" Width="Auto" Height ="{Binding altezza}"
   Source="intro.avi" LoadedBehavior="Manual" UnloadedBehavior="Stop">
</MediaElement>

In the .cs file I have this method

public int altezza{
   get { return 150; }
}

But it's not called from WPF element.

How I can fix it?

Thanks you for your reply

您必须将Datacontext设置为Codebehind文件：

DataContext="{Binding RelativeSource={RelativeSource Self}}"
