Using XAML resourceDictionary in code
提问by Enzojz
that's resourcedictionay file: TopologyTree.xaml
那是资源字典文件：TopologyTree.xaml
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:autoDraw.ViewModel.Topology"
>
<HierarchicalDataTemplate x:Key="TopologyTreeBase" DataType="{x:Type local:Base}" ItemsSource="{Binding children}">
<StackPanel Orientation="Horizontal">
<CheckBox IsChecked="{Binding IsChecked}"></CheckBox>
<TextBlock Text="{Binding name}"></TextBlock>
</StackPanel>
</HierarchicalDataTemplate>
</ResourceDictionary>
Side C#
侧面 C#
objectTree.Resources = new ResourceDictionary();
objectTree.Resources.Source = new Uri("GUI/TopologyTree.xaml", UriKind.Relative);
while objectTree is a TreeView
而 objectTree 是一个 TreeView
how ever that doesn't work.
这怎么行不通。
I have tried as followed which worked, but I need to redefine DataType here, so I think it's not so good.
我试过如下，效果很好，但我需要在这里重新定义DataType，所以我认为它不是那么好。
var resourceDictionary = new ResourceDictionary();
resourceDictionary.Source = new Uri("GUI/TopologyTree.xaml", UriKind.Relative);
objectTree.Resources.Add(
new DataTemplateKey(typeof(ViewModel.Topology.Base)),
resourceDictionary["TopologyTreeBase"] as HierarchicalDataTemplate
);
What's more, I have tried put the content of xaml into the xmal window directly as followed, That works, but I need it be loaded dyanmically, so it just proven that my xmal is good.
更重要的是，我已经尝试将xaml的内容直接放入xmal窗口，如下所示，这有效，但我需要动态加载它，所以它证明了我的xmal是好的。
<TreeView Name="objectTree" Grid.Column="4" Margin="3" Grid.Row="1" Grid.RowSpan="3">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type local:Topology.Base}" ItemsSource="{Binding children}">
<StackPanel Orientation="Horizontal">
<CheckBox IsChecked="{Binding IsChecked}"></CheckBox>
<TextBlock Text="{Binding name}"></TextBlock>
</StackPanel>
</HierarchicalDataTemplate>
</TreeView.Resources>
</TreeView>
Could anyone help me have a way to use it in C# side simply?
谁能帮我简单地在 C# 端使用它？

Hi let me show you example how to do it
嗨，让我向您展示如何操作的示例
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style TargetType="{x:Type TextBox}">
<Setter Property="Foreground" Value="Red"/>
</Style>
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:uc="clr-namespace:WpfApplication1"
xmlns:local="clr-namespace:WpfApplication1"
Width="1000" Height="1000"
Title="MainWindow" x:Name="abc">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="50"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBox x:Name="tbx"/>
</Grid>
tbx.Resources.MergedDictionaries.Add(
new ResourceDictionary { Source = new Uri(@"\Resources\MyResources.xaml", UriKind.Relative) });
Don't assign ResourceDictionary to Source , just add it to the Collection of MergedDictionary.
不要将 ResourceDictionary 分配给 Source ，只需将其添加到 MergedDictionary 的集合中。

Finally I've found the answer in this topic :
最后我在这个话题中找到了答案：
Adding to a TreeView a ResourceDictionary from another Assembly
将另一个程序集中的 ResourceDictionary 添加到 TreeView
That works.
那个有效。
