or,you can write the javascript function in aspx page and call it in pagebehind code for aspx page: function AlertMessage() { alert("hi"); } //disabling browser back button for mozila function noBack(){window.history.forward()} noBack(); window.onload=noBack; window.onpageshow=function(evt){if(evt.persisted)noBack()} window.onunload=function(){void(0)} //disabling browser back button for mozila function noBack(){window.history.forward()} noBack(); window.onload=noBack; window.onpageshow=function(evt){if(evt.persisted)noBack()} window.onunload=function(){void(0)} code for pagebehond: private void OkayAction_Click1( object sender, System. EventArgs e) { Page.ClientScript.RegisterStartupScript(this.GetType(), "", "AlertMessage();", true); }

Hi Mayank, It is expected that the second code will not work as in second code you have removed the single quotes and when it is written on the page it becomes local variable for JavaScript which does not exist. So if you want to run the second code then Message varaibel should exist in JavaScript.
