Introduction:
In this article i am going to explain about how to disable avoid browser back button functionality using javascript asp.net.

Main:

We can easily avoid the navigation of previous page(using browser back button) using the below simple script,

<script type = "text/javascript" > function InvalidBackButton() { window.history.forward(); } setTimeout("InvalidBackButton()", 0); </script>

If you wants in Code Behind,

string local_exestring = "&lt;SCRIPT language=javascript&gt;n"; local_exestring += "window.history.forward(1);n"; local_exestring += "n"; <strong>ClientScript.RegisterClientScriptBlock(this.Page.GetType(), "Script",local_exestring );</strong>

Conclusion:
Hope this helps,
Happy Coding.
