Hi Sascha,
You could the EditControl in SingleLine mode for this purpose. Please refer to the test sample attached here.
You have to manually code to behave as per your requirement, since EditControl doesn't provide inbuilt functionality.
Run the sample and type ";" at the end of the text in the EditControl. Note that the text gets automatically underlined like in Outlook. Also, when Delete or BackSpace key is pressed, it deletes the entire word.
Regards,
Mano
