How to retain formatting of existing text and append new text in Body field?

Hello,

I want to retrieve text which is present on the Calendar Entry form under the Body section (i.e. added in section )

and reinsert it after some modification.

For this I am using following code in lss:-

sBodyText = uidoc.FieldGetText(“Body”)

Message = sBodyText & CustomMessage

Entire “CustomMessage” needs to be reinserted on every change in it, therefore I cannot use

FieldAppendText.

and If I use FieldSetText and insert constructed “Message”, then all the previous formatting of sBodyText is lost.

Is there any way to retain formatting of existing text and append new text to it through lss?
