How to disable browser back button of a particular child page (Master Page)

[vingo_mail]

I have a problem to disable a browser back button of a particular child page(Not all child pages of a master page).
No problem when i use in a separate page. I may use history.forward script to onload property of a body tag in a page.
but now i m using master page. that's why i dont know to implement the rule. Could you help me regarding this.

Advance thanks

Welcome to DevX

Is it just one particular child page or could there be more than one child page for which the back button should be disabled?

Just only one particular child page. Sorry for the delay

Then couldn't you simply and an If the page equals the name of this child page, disable the Back button.

Incidentially, why do you want to disable the back button? I always find that annoying when that button is not available.
