[CLOSED] Error: 'theForm' is undefined

[marco.morreale]

I activated Ext.NET 2.0 Beta in an asp.net project with AjaxToolkit Extension.
As I add the resource manager to the master page I cannot change page in my gridviews. I got the following error:

Microsoft JScript runtime error: 'theForm' is undefined

In Visual Studio debugger I can see that the error occurrs in WebResourceXXX.axd file, here: (see // <------------- )

var __nonMSDOMBrowser = (window.navigator.appName.toLowerCase().indexOf('explorer') == -1);
var __theFormPostData = "";
var __theFormPostCollection = new Array();
var __callbackTextTypes = /^(text|password|hidden|search|tel|url|email|number|range|color|datetime|date|month|week|time|datetime-local)$/i;
function WebForm_InitCallback() {
    var count = theForm.elements.length;               // <------------- 
    var element;
    for (var i = 0; i < count; i++) {
        element = theForm.elements[i];
        var tagName = element.tagName.toLowerCase();
        if (tagName == "input") {
            var type = element.type;
            if ((__callbackTextTypes.test(type) || ((type == "checkbox" || type == "radio") && element.checked))
                && (element.id != "__EVENTVALIDATION")) {
                WebForm_InitCallbackAddField(element.name, element.value);
            }
        }
        else if (tagName == "select") {
            var selectCount = element.options.length;
            for (var j = 0; j < selectCount; j++) {
                var selectChild = element.options[j];
                if (selectChild.selected == true) {
                    WebForm_InitCallbackAddField(element.name, element.value);
                }
            }
        }
        else if (tagName == "textarea") {
            WebForm_InitCallbackAddField(element.name, element.value);
        }
    }
}

Hi,

Apologize for the delay, somehow we missed the thread.

We are investigating a possible fix. Thanks for the report.

I'm running into this also. Any update?

We have not came up with a fix yet.

Any idea what's causing it? This is a show stopper for me. I'm trying to use DevExpress controls within the Desktop and I'm getting this javascript error when I try to perform a callback.

I found a workaround. At the bottom of your aspx page (after the closing </form>), put the following:

    <script type="text/javascript">
<!--
        var theForm = document.forms['form1'];
        if (!theForm) {
            theForm = document.form1;
        }
        function __doPostBack(eventTarget, eventArgument) {
            if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
                theForm.__EVENTTARGET.value = eventTarget;
                theForm.__EVENTARGUMENT.value = eventArgument;
                theForm.submit();
            }
        }
// -->
    </script>

Be sure to replace "form1" with the ID of your main form.

Fixed in SVN

Please note that, by default, ViewState is disabled in v2 (it is removed from rendering)
If you need viewstate then please set DisableViewState="false" for ResourceManager (or in extnet section of web.config)
