How to save

http://docs.fckeditor.net/FCKeditor_2.x ... Script_API

function onSave() {
     alert('juhu!');
     return false;
}
/**
 * called when FCKeditor is done starting..
 * @param {Object} FCKeditor the instance that has
 */ 
function FCKeditor_OnComplete( editorInstance ){
    editorInstance.LinkedField.form.onsubmit = onSave;
}

How would this be implemented using CKEDITOR 3.0b2

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.

submit

 youform.onsubmit = function()
{
  return yourCustomProcessingResult; // A 'false' will prevent editor from submitting the form.
}

Yes, but...what if I have other things on that page that submit to the page that the fckEditor is on? This doesn't make sense to me. Because, I don't have a clear way to identify if the save button ON THE fckEditor was actually clicked. Right? What am I missing?
