SAVE BUTTON

A little AJAX works magic in this situation. I'm not sure if there are any PHP modules that explicitly hook up AJAX and an FCKeditor, though.

Yes, how the heck is saving done?? I don't get it, I've gone through pages and pages in this forum without success.

Currently, I am saving the HTML of the fckEditor on every Page_Load, as the 'Save' button submits the form. However, this seems juvenile and unprofessional.
How can I utilize something like the __doPostBack function where I can pass in the Id and Argument so that I can retrieve these values in the code behind and test for them properly?
I want to click save on the save icon in the toolbar and have it postback to the server with a saveId and/or specific argument that I can look for to tell when the 'save' button has been clicked. I've read several posts similar to this, but it seems no-one is able to actually do it.

I get that the 'save' button is simply a submit button. I can see in the fckConfig.js file where the form is submitting:

FCKSaveCommand.prototype.Execute = function() {
    var A = FCK.GetParentForm();
    if (typeof (A.onsubmit) == 'function') {
        var B = A.onsubmit();
        if (B != null && B === false) return;
    };
    if (typeof (A.submit) == 'function') A.submit();
    else A.submit.click();
};

Yeah i get that can change the A.submit to call my own function to perform the postback.
However, when i substitue the A.submit to use __doPostBack('myIdOfTheCtrlHere', 'myArgumentHere'), the __doPostBack function is unrecognized.

Help please.
