Using XAML resourceDictionary in Code
resourcedictionay file: 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>
C # side
objectTree.Resources = new ResourceDictionary();
objectTree.Resources.Source = new Uri("GUI/TopologyTree.xaml", UriKind.Relative);
and objectTree is a TreeView
how it doesn't work.
I tried how it works, but I need to override DataType here, so I think it is not that good.
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 tried to put the xaml content in the xmal window directly like below. This works, but I need it to load diacritically, so it just proved my xmal is good.
<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>
Can anyone help me have a way to use it in C # side simply?

Hi let me show you an example how to do this
<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 a ResourceDictionary to the Source, just add it to the Collection of MergedDictionary.

Finally, I found the answer in this section:
Adding a ResourceDictionary to a TreeView from another assembly
It works.
