Example: Executing Actions through Commands

You can execute the actions in the RichTextEditor through the provided commands. For example, you can apply bold text formatting from a custom UI other than the RichTextEditor toolbar.

The following example how to call the RadRichTextEditor commands on a button click action.

1. Let's add the RichTextEditor definition together with a few sample buttons wired to the editor's commands:

xaml

<Grid RowDefinitions="Auto, *">
    <telerik:RadUniformGrid>
        <Button Text="Bold"
                Command="{Binding ToggleBoldCommand, Source={x:Reference richTextEditor}}"
                Margin="0, 0, 10, 10" />
        <Button Text="Italic"
                Command="{Binding ToggleItalicCommand, Source={x:Reference richTextEditor}}"
                Margin="0, 0, 10, 10" />
        <Button Text="Underline"
                Command="{Binding ToggleUnderlineCommand, Source={x:Reference richTextEditor}}"
                Margin="0, 0, 10, 10" />
        <Button Text="Bulleted List"
                Command="{Binding ToggleBulletingCommand, Source={x:Reference richTextEditor}}"
                Margin="0, 0, 10, 10" />
        <Button Text="Numbered List"
                Command="{Binding ToggleNumberingCommand, Source={x:Reference richTextEditor}}"
                Margin="0, 0, 10, 10" />
    </telerik:RadUniformGrid>
    <telerik:RadRichTextEditor x:Name="richTextEditor" Grid.Row="1" />
</Grid>

2. Add the required namespaces:

XAML

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

For a runnable example with the RichTextEditor commands, see the SDKBrowser Demo Application and go to RichTextEditor > Features.
