I've found this post helpful

i'm essentially trying to access the entered html from a TextEditor dnn control (like freetextbox or FCKEditor). I cant locate its content thru request.form (probably due to the fact that the editor's content is generated in an iFrame).

Due to the complexity of this type of control, is grabbing its value in a callback impossible?

The only work around i found was to implement each independent text editors JavaScript API

So i got references from the major text editors:

• http://wiki.fckeditor.net/Developer's_Guide/Javascript_API
• http://cutesoft.net/developer+guide/javascript-api.htm
• http://freetextbox.com/demos/javascript.aspx
• http://www.telerik.com/help/radeditor/5.6/?r.a.d.editor%20Client-Side%20Events.html

And the JS looks something like this:

function storeDescFCK(ctx)
{
    var oEditor = FCKeditorAPI.GetInstance(ctx + '_txtDescription_txtDescription');
    dnn.setVar('Desc', oEditor.GetHTML());
}
function storeDescFTB(ctx)
{
    dnn.setVar('Desc', FTB_API[ctx + '_txtDescription'].GetHtml());
}
function storeDescCute(ctx)
{
    var oEditor = document.getElementById(ctx + '_txtDescription');
    dnn.setVar('Desc', oEditor.getHTML());
}
function storeDescRad(ctx)
{
    var oEditor = GetRadEditor(ctx + '_txtDescription');
    dnn.setVar('Desc', oEditor.GetHtml());
}

And i do a dual js call on the onclick event (one is to implement on of these functions, the other is the callback. These two are separated by a ;  ... ie:    d be better if i didnt have to dig this deep. Any suggestions?

Sorry I haven't looked that closely at the text editor situation.

Sounds like you are having to implement something similar to what I did in the ClientAPI with the XMLHTTP object, where in IE I use an ActiveX control, in FireFox/Mozilla I use another object, and in Opera/Safari, I coded it completely in javascript.   Basically I created a standard interface that wrapped each implementation so that the calling code doesn't care.  I'm guessing you may want to do something similar so you can protect yourself from future changes or new implementations.
