cannot do postback with HtmlEditorExtender and ie11


Found a postback problem because of the JavaScript runtime error: Invalid argument in the _editableDiv_submit of the htmleditor when using internet explorer 11.

The page didn't postback with ie11 and the htmleditor together because it found a problem in sel.collapse(this._editableDiv.firstChild, char) of the _editableDiv_submit

because didn't have much time I decided to temporary fix the function with the below:
if (!!navigator.userAgent.match(/Trident\/7\./) && Sys.Extended && Sys.Extended.UI && Sys.Extended.UI.HtmlEditorExtenderBehavior &&
    Sys.Extended.UI.HtmlEditorExtenderBehavior.prototype && Sys.Extended.UI.HtmlEditorExtenderBehavior.prototype._editableDiv_submit) {
    Sys.Extended.UI.HtmlEditorExtenderBehavior.prototype._editableDiv_submit = function () {
        var char = 3;
        var sel = null;
        setTimeout(function () {
            if (this._editableDiv != null)
        }, 0);                     
        this._textbox._element.value = this._encodeHtml();

Yes, I am also facing the problem with Win 8 Pro (64bit) IE 11. Firefox is working fine.

Please help us to fix.

I have this problem too.

I would like to try this temporary fix. Where am I supposed to add this piece of code?

As with the others, I too am having this problem. How do I go about patching the code with the sample above?

Ahh, okay. I added the JS to the bottom of my page and all is now well.

Just upgraded to v15 and experienced the same issue with IE 11. Implemented all the static scripts so that I could get at the JavaScript and commented out the line below for a workaround.
    if(Sys.Browser.agent != Sys.Browser.Firefox) {
        if (document.selection) {
            sel = document.selection.createRange();
            sel.moveStart('character', char);
        } else {
            sel = window.getSelection();
           // sel.collapse(this._editableDiv.firstChild, char);

This issue will be fixed in the future release. Related changeset 3f2a2942a0ca.
Until the next release is provided, you can use a workaround suggested in ticket 27547.
