System.Windows.Data错误：40：BindingExpression路径错误：属性对象上未找到 [英] System.Windows.Data Error: 40 : BindingExpression path error: property not found on object

问题描述

许多歉意添加到类似的绑定错误问题，大量的名单在那里，但搜索我不能找到一个解决方案，为我工作了几个小时之后！

Many apologies to add to the massive list of similar binding error questions out there, but after hours of searching I can't find a solution that will work for me!

我想在WPF来测试视图模型，但ICommand的按钮代码导致该标准绑定错误：

I am trying to test a ViewModel in WPF, but the ICommand Button code is causing the standard binding error:

System.Windows。数据错误：40：BindingExpression路径错误：'CheckforNewHubs'属性不是'对象'''HubManagerViewModel'（的hashCode = 13328197）找到。 BindingExpression：路径= CheckforNewHubs;的DataItem ='HubManagerViewModel'（的hashCode = 13328197）;目标元素是'按钮'（名称='CheckForNewHubsButton'）;目标属性命令（类型'的ICommand'）

System.Windows.Data Error: 40 : BindingExpression path error: 'CheckforNewHubs' property not found on 'object' ''HubManagerViewModel' (HashCode=13328197)'. BindingExpression:Path=CheckforNewHubs; DataItem='HubManagerViewModel' (HashCode=13328197); target element is 'Button' (Name='CheckForNewHubsButton'); target property is 'Command' (type 'ICommand')

我的命令（在HubManagerViewModel）是：

my command (in HubManagerViewModel) is:

public ICommand CheckForNewHubs
    {
        get{
            return new RelayCommand(this.CheckForNewHubsExecute, this.CanSendHubManagerCommands);
        }
        set { }
    }

和我的DataContext是在XAML网发起的为：

and my DataContext is initiated in an XAML grid as:

<Grid.DataContext>
    <ViewModels:HubManagerViewModel/>
</Grid.DataContext>

我曾尝试明确设置按钮的DataContext的是这样的：

I have tried explicitly setting the dataContext of the button like this:

<Button.DataContext>
    <ViewModels:HubManagerViewModel/>
</Button.DataContext>

但无济于事：（

but to no avail :(

谁能告诉我什么，我做错了吗？在这一点上，我只是绝望了一些新的见解。

Can anyone tell me what I'm doing wrong? At this point I'm just desperate for some new insight.

感谢您的时间提前！

推荐答案

您已经使用绑定路径 CheckforNewHubs ，但它应该是 CheckForNewHubs 。

You have used Binding Path CheckforNewHubs but it should be CheckForNewHubs.
