I have downloaded the component(TextArea control) from your site.
Undo and Redo functionality is not working properly. Please let me know whether you have any fix for this issue.

We don't have any component like that.
Can you post the url to the textarea control?
I don't think it's ours. Try tinymce. That's what we use.
