我學習創建下面這個tutorial的MVVM應用程序,它有這個在它的入口視圖時WPF MVVM錯誤:有關查看和視圖模型
什麼的例子
<UserControl.Resources>
<DataTemplate DataType="{x:Type vm:ProductViewModel}">
<vw:ProductView />
</DataTemplate>
<DataTemplate DataType="{x:Type vm:SingleBrandViewModel}">
<vw:SingleBrandView />
</DataTemplate>
</UserControl.Resources>
工作所以我想在我的代碼如下
什麼也沒有在我的代碼工作
<Page x:Class="MvvmAttempt.FilesView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="clr-namespace:MvvmAttempt"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300"
Title="FilesView">
<Page.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="resources/Styles.xaml" />
</ResourceDictionary.MergedDictionaries>
<local:MySizeConverter x:Key="sizeConverter"/>
<DataTemplate DataType="{x:Type local:SingleFileView}"> <--- error here
<local:SingleFileViewModel/> <--- error here
</DataTemplate>
</ResourceDictionary>
</Page.Resources>
... other stuff ...
</Page>
x:Type
有下劃線的錯誤消息:The type 'x:Type' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.
<local:SingleFileViewModel/>
下,誤差爲:The specified value cannot be assigned. The following type was expected: "DependencyObject".
什麼引起的錯誤?爲什麼在示例代碼中沒有任何內容時期望DependencyObject
?謝謝!
謝謝!現在'x:Type'這行仍然存在抱怨,但它編譯得很好。所以猜我會忽略它... – totoro 2014-11-02 07:51:45
