的来源，这可能是一个非常基本的问题，我是新来Silverlight和MVVM，如何查找绑定属性

我有一个按钮

<Button IsEnabled="{Binding IsUpdatingStatus}"> </Button>

只是想知道如果我有找到IsUpdatingStatus（其中视图模型存在） 的源在哪里可以看到的方向开始在XAML

编辑：

我的XAML有类似这样的标记：

<UserControl x:Class="LMS.Client.View.LeadStatusControl" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk" 
     xmlns:vc="clr-namespace:LMS.Client.Controls" 
     xmlns:control="clr-namespace:LMS.Client.Controls;assembly=LMS.Client.Common" 
     xmlns:commanding="clr-namespace:LMS.Client.Commanding;assembly=LMS.Client.Common" 
     mc:Ignorable="d"> 

     <ContentControl Style="{StaticResource Content.ContentControlStyle}"> 

    .....

如果我失去了一些东西，请让我知道，告诉我，如果我什么不对

this is actually complete Xaml

在运行时，你可以用Snoop检查这个，但在设计时我不知道是否有工具或扩展可以帮助你 – blindmeis

Button的DataContext属性将为您提供绑定属性的来源。

要使数据绑定生效，需要将DataContext设置为ViewModel。你可以用不同的方式做到这一点。例如，在页面的构造函数：

Page.xaml.cs

public Page() 
{ 
    DataContext = new PageViewModel(); 
}

当你在你的PageViewModel名为IsUpdatingStatus一个布尔属性，该按钮会再根据什么IsUpdatingStatus设置更新其状态至。

有些人不喜欢使用构造函数来设置DataContext。您也可以静态设置它在XAML文件本身，也看到了答案this question，或者使用的OnNavigatedTo事件处理程序：

protected override void OnNavigatedTo(NavigationEventArgs e) { }

我希望这（部分）回答你的问题。
