NOTE

Starting with v16.2.0.41 (2018 Vol 2), if you reference Syncfusion® assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion® license key in your WPF application to use our components.

Adding SfRichTextBoxAdv to an application

After adding the aforementioned assembly references to your application, you can add SfRichTextBoxAdv as any normal control.
You can either drag the SfRichTextBoxAdv control from the toolbox window to the Design view or directly define the control in XAML view.

XAML

<RichTextBoxAdv:SfRichTextBoxAdv x:Name="richTextBoxAdv" xmlns:RichTextBoxAdv="clr-namespace:Syncfusion.Windows.Controls.RichTextBoxAdv;assembly=Syncfusion.SfRichTextBoxAdv.Wpf" />

C#

// Initializes a new instance of RichTextBoxAdv.
SfRichTextBoxAdv richTextBoxAdv = new SfRichTextBoxAdv();

Creating Document editor with Ribbon

This section discusses about how to create document editor with ribbon similar to Microsoft Word. The SfRichTextRibbon is a Ribbon control customized to work with SfRichTextBoxAdv control, which gives you the look and feel of Microsoft Word.
You can find the SfRichTextRibbon control from the following assembly under the namespace Syncfusion.Windows.Controls.RichTextBoxAdv

• Syncfusion.SfRichTextRibbon.WPF

The following assembly reference are additionally required to deploy SfRichTextRibbon control along with aforementioned assemblies.

• Syncfusion.Tools.WPF

Adding the Control via Designer

1. Create new WPF application in Visual Studio

2. Use the Syncfusion® RibbonWindow instead of Window

1. Drag the SfRichTextRibbon control from the Toolbox window to the Design View. An instance of the SfRichTextRibbon control is created in the Design view

1. Drag the SfRichTextBoxAdv control from the Toolbox window to the Design View. An instance of the SfRichTextBoxAdv control is created in the Design view

1. To make an interaction between SfRichTextRibbon and SfRichTextBoxAdv, bind the SfRichTextBoxAdv as DataContext to the SfRichTextRibbon

   XAML

   <Syncfusion:SfRichTextRibbon x:Name="richTextRibbon SnapsToDevicePixels="True" DataContext="{Binding ElementName=richTextBoxAdv}" />

Adding Control via code.

You can also add the SfRichTextRibbon and SfRichTextBoxAdv programmatically by using XAML

XAML

<Syncfusion:RibbonWindow x:Class="DocumentEditor.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:DocumentEditor"
        mc:Ignorable="d"
        xmlns:Syncfusion="http://schemas.syncfusion.com/wpf"
        Title="MainWindow" Height="350" Width="525" Syncfusion:SfSkinManager.Theme="{Syncfusion:SkinManagerExtension ThemeName=FluentLight}">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <Syncfusion:SfRichTextRibbon x:Name="richTextRibbon" SnapsToDevicePixels="True"/>
        <Syncfusion:SfRichTextBoxAdv x:Name="richTextBoxAdv" Background="#F1F1F1" Grid.Row="1"></Syncfusion:SfRichTextBoxAdv>
    </Grid>
</Syncfusion:RibbonWindow>

NOTE

Prefer using SfRichTextRibbon within RibbonWindow in your application, since the backstage of Ribbon will be opened only when the ribbon is loaded under the RibbonWindow

Finally, you can get the following output similar to Microsoft Word on executing the application

Theme

SfRichTextBoxAdv supports various built-in themes. Refer to the below links to apply themes for the SfRichTextBoxAdv,

• Apply theme using SfSkinManager

• Create a custom theme using ThemeStudio
