Character count

The RichTextEditor automatically counts the number of characters in the content are while typing using the showCharCount property. The characters count displayed at the bottom of the editor. You can limit the number of characters in your content using the maxLength property. By default, the editor sets the characters limit value is infinity.

The character count color will be modified based on the characters in the RichTextEditor.

Status Description
normal Till 70% of given maxLength count reach, character count color is black.
warning Once the number of character count in the RichTextEditor reached 70% of given maxLength count, the character count color will be orange, indicating that, the RichTextEditor value going to reach the maximum count.
error Once the number of character count in the RichTextEditor reached 90% of given maxLength count, the character count color will be red, indicating that, the RichTextEditor value reached the maximum count.

To create RichTextEditor with Character Count feature, inject the Count module to the RTE using the RichTextEditor.Inject(Count) method.

Code view

RichTextEditor includes the ability for users to directly edit HTML code via Source View in the text area. If you made any modification in Source view directly, the changes will be reflected in the RichTextEditor’s content. So, the users will have more flexibility over the content they have created.

Undo/Redo Manager

Undo and redo tools allow you to edit the text by disregard/cancel the recently made changes and restore it to previous state. It is a useful tool to restore the performed action which got changed by mistake. By default, upto 30 actions can be undo/redo in the editor.

To undo and redo operations, do one of the following:

  • Press the undo/redo button on the toolbar
  • Press the Ctrl + Z/Ctrl + Y combination on the keyboard

Customize the undo/redo step count using undoRedoSteps property. By default, undo/redo actions take 300ms time interval for store the action to the undoRedoManager. The time interval can be customized by using the undoRedoTimer.
