I'm puzzled: there is not such property:
System.Windows.Forms.RichTextBox.HScrollBar!
!
You probably mixed up something. You could would not compile even if you don't assign it a value.
—SAUPDATE:
[SM]: Just adding a link to all available properties for RichTextBox class:
MSDN: RichTextBox Class[

Sandeep, do you confirm that there is no such property, in case I've gone crasy? :-)
There is not such property, correct?
