RichTextEditor Toolbar

The RichTextEditor control comes with various editing capabilities. With the help of the RadRichTextEditorToolbar, you can enable the users to effortlessly edit HTML content. The default toolbar includes items for all the available text formatting options. Alternatively, you can customize the shown editing options according to your needs.

By default, the RadRichTextEditorToolbar Items are auto-populated. You can change this by setting the RadRichTextEditorToolbar boolean AutoGenerateItems property to False. In this case, you will need to manually define the available editing options. For more details, check Custom Toolbar article.

To attach the RichTextEditor control to the RadRichTextEditorToolbar control, you need to set the RichTextEditor (from type RadRichTextEditor) property. All toolbar items execute their actions against the specified rich text editor.

The Toolbar is part of Telerik UI for .NET MAUI, the most comprehensive UI suite for .NET MAUI! To try it out, sign up for a free 30-day trial and kickstart your cross-platform app development today.

RichTextEditor Toolbar Placement

Some specifics you'd need to take into account when placing RichTextEditorToolbar on the page:

• On Android—When you place the RichTextEditor Toolbar below the RichTextEditor, you set the Application's WindowSoftInputModeAdjust to Resize. This setting causes the page to resize when the keyboard is shown, and in this way, if the RichTextEditorToolbar is on the bottom of the page, it will be displayed over the keyboard when it appears.

You can apply it on application level like this:

App.Current.On<Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Resize);

For more details, check the Soft Keyboard Input Mode on Android from .NET MAUI documentation.

• On iOS—If the RadRichTextEditorToolbar is positioned under the keyboard, when the keyboard shows, the control is translated over the keyboard so users can access it without a problem. Due to the .NET MAUI implementation, it is important that the RadRichTextEditorToolbar is placed in a container which bounds will contain it after the control is translated over the keyboard. Otherwise, the tap and pan gestures on the RadRichTextEditorToolbar will not work until the keyboard is hidden and the control is translated back to its original place.
• RichTextEditorToolbar must have a greater ZIndex than the other elements in its parent layout to be visible (and not behind other views, like RichTextEditor) when translated over the keyboard. Also, it must be contained in the bounds of its parent layout after translation. In this case, set the ZIndex property to the RichTextEditorToolbar.

For the RichTextEditor Toolbar examples, see the SDKBrowser Demo Application and go to RichTextEditor > Toolbar.

Custom Toolbar

You can customize the toolbar by setting the AutoGenerateItems to False. Then decide which toolbar items to include. For more details on this—Review the Custom Toolbar article.
