Hi Radhika,
is this control a Telerik radcontrol like the one seen in this demo:
http://demos.telerik.com/silverlight/#RichTextBox/MSWord
?
Each word in the RadRichTextEditor should be a separate textbox. I've confirmed this behavior not only with our own Telerik RadRichTextbox control but also controls manufactured from other companies.
If your control is not a Telerik control - can you find a demo pages that has this type of control somewhere online. We will use the demo to examine the control and determine how to test it.
Hope to hear from you soon.
Regards,
Stoich
