I need to call some codeBehind function from JavaScript. For this, I have a hidden button (asp:Button).

When I click this button from javaScript like:

var btn = document.getElementById("btnHidden");
btn.click();

I got an error:

System.Web.HttpException: The state information is invalid for this page and might be corrupted.

Could you please help me?
