Question

How do I pass this.href from asp.net code behind? Here is what I have, and in javascript I added a alert to see the value and it says ‘undefined’

Page.ClientScript.RegisterStartupScript(this.GetType(), "Sample", "Callscript(this.href);", true);

function Callscript(href) 
{
    alert(href);
}

href is not a property of the global object. i believe you are looking for window.location.href:

Page.ClientScript.RegisterStartupScript(this.GetType(), "Sample", "Callscript(window.location.href);", true);
