Getting Started with WPF SyntaxEditor
This tutorial will walk you through the creation of a sample application that contains a RadSyntaxEditor control.
Assembly References
In order to use RadSyntaxEditor, you will need to add references to the following assemblies:
- Telerik.Windows.Controls
- Telerik.Windows.Controls.Input
- Telerik.Windows.Controls.SyntaxEditor
- Telerik.Windows.SyntaxEditor.Core
You can find the required assemblies for each control from the suite in the Controls Dependencies help article.
Defining RadSyntaxEditor
Example 1 demonstrates how you can define a RadSyntaxEditor in XAML.
Example 1: Defining RadSyntaxEditor
<telerik:RadSyntaxEditor x:Name="syntaxEditor" />

Opening a File
To load a file in the RadSyntaxEditor you need to use its Document property.
Example 2: Opening a File
public MainWindow()
{
InitializeComponent();
using (StreamReader reader = new StreamReader("../../CS_File.txt"))
{
this.syntaxEditor.Document = new TextDocument(reader);
}
}

Enable Syntax Highlighting
Once you have loaded the code, you need to register an appropriate tagger to enable syntax highlighting for the particular language.
Example 3: Enable C# code highlighting
var cSharptagger = new CSharpTagger(this.syntaxEditor);
this.syntaxEditor.TaggersRegistry.RegisterTagger(cSharptagger);

Setting a Theme
The controls from our suite support different themes. You can see how to apply a theme different than the default one in the Setting a Theme help article.
Changing the theme using implicit styles will affect all controls that have styles defined in the merged resource dictionaries. This is applicable only for the controls in the scope in which the resources are merged.
To change the theme, you can follow the steps below:
Choose between the themes and add reference to the corresponding theme assembly (ex: Telerik.Windows.Themes.Windows8.dll). You can see the different themes applied in the Theming examples from our WPF Controls Examples application.
-
Merge the ResourceDictionaries with the namespace required for the controls that you are using from the theme assembly. For the RadSyntaxEditor, you will need to merge the following resources:
- Telerik.Windows.Controls
- Telerik.Windows.Controls.Input
- Telerik.Windows.Controls.SyntaxEditor
- Telerik.Windows.SyntaxEditor.Core
Example 3 demonstrates how to merge the ResourceDictionaries so that they are applied globally for the entire application.
Example 3: Merge the ResourceDictionaries
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/System.Windows.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.SyntaxEditor.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Alternatively, you can use the theme of the control via the StyleManager.
