Try this: protected override void OnPreRender(EventArgs e) { base.OnPreRender(e); string sb; sb =  
; sb += window.history.forward(1);
; sb += 
 ; Page.RegisterClientScriptBlock(clientScript sb); }

Milton Smith · Answer

I have no clue what you are talking about. Can you send me the sample code???

Niradhip Chakraborty · Answer

Well the only way you can do it by overriding the page's OnPreRender method.

Milton Smith · Answer

Well khan I told you I don’t have any problem to use client side scripting but I should use some method or event to perform it and everything should be written in pagebehind. Thanks for your explanation but it will not work in my case. Moreover I told you I want serverside coding. So no point on discussing about only client side execution.

Arshad · Answer

First of all C# is not a web technology for that u will have to go to the ServerSide(ASP.NET) Feature or else ClientSide(JavaScript). its not Possible with the Core C# funda Try to use Asp.Net Feature or else u can do this by the Javascript this it the Best way to do. It wont be Bother on the Server it will execute at the Client side only.

It's not like that. My requirement is simple. I want to use c# code to accomplish this tusk but I don’t want to use smart navigation property. I don’t have any problem to use JavaScript code but I should use c# coding.

Niradhip Chakraborty · Answer

Milton Smith · Answer

It's not a caching problemI guess and it's not working.

Milton Smith · Answer

No khan There is no login or logout concept in my form. It's simple as soon as I go to 2nd page from 1st page it should not allow user to go back to 1st page while clicking on browser back button.

Arshad · Answer

If its that problem then add these two line in your Page Load Response.Cache.SetExpires(Now) Response.Cache.SetCacheability(HttpCacheability.NoCache) That will work Thanks

Arshad · Answer

Hey Milton tell me one thing likeif some one Logged out from there Home page so its going to the Login page but while clicking on the Back button still its going to the Home Page Is your Problem Like that. tell me????????????????

Milton Smith · Answer

No Khan it's not like that. I don't want to use smart navigation property. Can it be done by some other way in pagebehind.

Arshad · Answer

Milton Smith · Answer
