如何在asp.net中的page_load之外访问__doPostBack Eventtarget值？

Question

I am using __doPostBack to send data from JavaScript to code behind page in ASP.NET application.

The JavaScript is as follows,

$('.window_month td').on('click', function () {
    var idName = this.id;
    var selectedid = idName.substring(1);
    $('#hidden').val(selectedid);
    __doPostBack(idName, '');
});

I am using the variable like this in .cs page,

string s = Request["__EVENTTARGET"];

I want to use this __EVENTTARGET value outside of page_load and assign it to a global variable in ASP.NET.

How can I do this?

Used Session and it worked. Thanks all.

then you will need to have a static property or store it in a Session variable because if your are doing postbacks on the page load the public string variable would be overwritten and set to string.Empty on every page load.. I would personally initialize a HttpContext.Current.Session["Target"] = string.Empty in the Global.asax page in the OnSessionStart() method and then assign it and from there you can access it application wide.. does that make sense..? :)
