How to submit some or All controls in an ASPX page using HTTP post

Question

I have an aspx page named ShowDesign.aspx and it is browsed using URL myurl.com/showdesign.aspx?id=420420

The aspx page has many controls such as image, text button, radio buttons etc. Some of the controls are created in code-behind and the values to most of the controls are assigned/updated in code-behind.

When the page is ready to be displayed, I would like to use HTTP Post on some the controls (otherwise use HTTP post for entire page). I have not done this and would like to know how to do it? What code should I add and where should I add in the code-behind?

Update Want to know the below Javascript will do what I am looking for? I am still checking it. If anyone has any feedback, please update.

function postToURL(url, values) {
    values = values || {};

    var form = createElement("form", {action: url,
                                      method: "POST",
                                      style: "display: none"});
    for (var property in values) {
        if (values.hasOwnProperty(property)) {
            var value = values[property];
            if (value instanceof Array) {
                for (var i = 0, l = value.length; i < l; i++) {
                    form.appendChild(createElement("input", {type: "hidden",
                                                             name: property,
                                                             value: value[i]}));
                }
            }
            else {
                form.appendChild(createElement("input", {type: "hidden",
                                                         name: property,
                                                         value: value}));
            }
        }
    }
    document.body.appendChild(form);
    form.submit();
    document.body.removeChild(form);
}
</script>
