The richtextbox not receiving the keys such Ctrl+A, Ctrl+O when typedon it when hosted on web page

[Gouri.Mahajan7]

Hello,

I have hosted the windows user control (which has one richtextbox) on
web page. When I type the keys such as Ctrl+O on it the open window
pops up and the control (i.e. richtextbox) is not receiving that
character. Same with some other shortcut keys such as Ctrl+P, Ctrl+A
and so on. Can anybody please give me the solution for it.?? The
control should receive such characters when typed on it on web page.

Thanks in advance.

Regards,
Gouri.
