You're living in a fantasy. You can't stop the user going back. Instead, you should fix your overall design.

For what reason do you want to disable the back button? Many, including myself, use the back button often and I would consider it to be a usability issue if I couldn't go back a page easily.

thanks for ur answers. Ex:If menu contains, page1 page2 page3 and logout page. after login,he can go to page2 and page1 with back button,but from page1 he should not go to login page with browsers.With logout only he can go back to login page. once user login,and reached main menu page,until unless he clicked on the logout,he should not go back to the login page by clicking on the browers back button. This is my requirement.Please let me know if any one of u understand and had solution.

Just as long as the page isn't cached then you can handle what to do in the one of the page events (not sure of the best one, maybe page_load?). That is, if the user is logged in and he/she tries to go back to the login page then hide the login form and maybe show a message saying 'Already Logged In' or something. If the user has logged out and he/she tries to go back to a secured page then re-direct to the login page. I think you can set whether to cache the page or not using the Response object.

Like I said, if you fix your site, then you will solve your problem. Write good code, don't try to hack your way through bad code.

Try this out; protected void Page_load { StringBuilder javaScript = new StringBuilder(); javaScript.Append("\n<script language=JavaScript>\n"); javaScript.Append("window.history.forward(1);\n"); javaScript.Append("</script>\n"); Page.RegisterClientScriptBlock("HistoryScript", javaScript.ToString()); } Its a bit of a trick, but works for me. The real problem is that newer browsers purposefully remove the ability for code to effect the menus of the browser now as some nasty hackers keep finding ways to hijack the browser using these methods. Probably the code above will become useless after a time too when someone starts to use it in-appropriately and we will have to creatively come up with a new method. Just be cautious in how you apply it. :cool:

For GOD'S sake abandon the way you're doing it. Many MANY people post similar questions, and the answer's always the same. If you NEED to disable standard controls in the browser for your site to work, you've designed it WRONGLY. Not sure I understand what you're asking, but I suspect that it's that you don't want users to redirect to a login page they've already completed - if that's the case, look at Forms authentication in MSDN...but please PLEASE don't start hacking the browser just to make things work - it's not only really silly, but it also gives others the idea that it's OK!
C# has already designed away most of the tedium of C++.
