onParentNodeChanged() causes an Cannot read property 'defaultView' of undefined error in Chrome 73

This can be reproduced with the following sample:

<telerik:RadWindow runat="server" ID="RadWindowWithEditor" Height="1000px" OnClientShow="fixEditor"
 
    OpenerElementID="Button5">
    <ContentTemplate>
        <telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1" Width="700px" Height="700px">
            <Content>
Lorem ipsum dolor sit amet
            </Content>
        </telerik:RadEditor>
    </ContentTemplate>
</telerik:RadWindow>
<asp:Button ID="Button5" Text="open the RadWindow" runat="server" />
<script type="text/javascript">
    function fixEditor() {
        setTimeout(function () {
            $find("<%=RadEditor1.ClientID %>").onParentNodeChanged();
        }, 100);
    }
</script>

Hi Rajiv,

I am unable to repro this issue, but anyway it is not related to the feedback bug report item.

Please let's continue the communication is an appropriate support channel for technical assistance: in the Telerik AJAX forums or a support ticket.

Please isolate the problem in a simplified runnable page or project and send it for examination.

On a side note, if the toolbar reappears properly when the set_useClassicDialogs is called and you are OK with its appearance, you can use this as a workaround. The purpose of is to replace RadWindow with the browser window dialog as explained at Using browser modal dialog instead of RadWindow.

The only reason to fire this method is to prevent the popup blocking of your browser, but I haven't faced such an issue from years.

Thanks for your reply.

But Rumen its not working for me.

Actually the issue is at this line of code editor.set_useClassicDialogs(true);

While i set it to false its working fine but when it is true toolbar not coming.

 

Thanks.

Hi Rajiv,

I noticed that you are using a customized the solution from https://www.telerik.com/support/kb/aspnet-ajax/details/setting-hidden-radeditor-in-edit-mode-on-click-and-putting-it-in-non-editable-mode-onblur and now the code throws the 

Cannot read property 'getElementsByTagName' of null error, due to this line: 

var editorIframe = $get(editor.get_id() + "Wrapper").getElementsByTagName("iframe")[0];

You can obtain the editor's Iframe content area element with this API code:

var editorIframe = editor.get_contentAreaElement();

You can also use the attach the key event to the content area using the attachEventHandler method of the editor:

editor.attachEventHandler("onkeydown", function (e) { alert("Content area key down " + e.keyCode); });

Also set the RadEditor's ToolbarMode="ShowOnFocus" and try again.

On a side note, please use the support ticketing system or the forums for any technical communications. Right now the reported issue is neither related to the original bug report, nor a bug in the control and the feedback portal is not suitable source for researching it.

Thank you for your understanding!

Rumen

Hi Rajiv,

Thank you very much for the sample file!

I managed to reproduce the "Cannot read property 'selection' of undefined" error even with a version from 2015. The bug is not related to the one reported in this bug report item and can be fixed by calling the set_html() method with a small timeout:

setTimeout(function () {
    editor.set_html(target.innerHTML);
}, 100);

Can you please modify the test page Default2.aspx so that it exhibits the problem and send it back for examination?

Thank you very much!

Hi,

I downloaded hot fix build Telerik_UI_for_ASP.NET_AJAX_2019_1_318_Trial_hotfix.zip and add dll in my project.

But still i am getting same error message in consol. It does not affect my application but why i am getting this error.

 

As i told you earlier that some design affected. for example radeditor height became small which is in iframe.

 

Earlier iframe style was height:100% and width:100%

Now iframe style was height:35px and width:100%

 

 

If you have any idea then please let me know.

 

I am trying to give you a demo solution project.

Hi Rajiv,

Can you please go to https://www.telerik.com/account/product-download?product=RCAJAX -> click on the Internal Builds tab and download -> Telerik_UI_for_ASP.NET_AJAX_2019_1_318_Trial_hotfix.zip?

After that update your application with it and see whether the newly "Cannot read property 'selection' of undefined" reported error still persists.

If it is there, please provide a simple runnable project which reproduces the error so that I can debug it. Thank you!

Rumen

Hi Nick,

Thank you for reporting this Chrome 73 regression.

We will fix the problem in the upcoming R2 2019 version of the controls. Right now you can solve it with the following function override:

<script type="text/javascript">
 
    Telerik.Web.UI.Editor.Utils.isWindowDestroyed = function (window) {
        var doc;
        try{
            doc = window.document;
        } catch (e) {
            return true;
        }
        if (!doc) {
            return true;
        }
        return !doc.defaultView && !doc.parentWindow;
    }

Here is a complete sample which works properly on my side in Chrome 73:

  <telerik:RadWindow  runat="server" ID="RadWindowWithEditor" Height="1000px" OnClientShow="fixEditor"
    OpenerElementID="Button5">
    <ContentTemplate>
        <telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1" Width="700px" Height="700px">
            <Content>
                Lorem ipsum dolor sit amet
            </Content>
        </telerik:RadEditor>
    </ContentTemplate>
</telerik:RadWindow>
<asp:Button ID="Button5" Text="open the RadWindow" runat="server" />
<script type="text/javascript">
 
    Telerik.Web.UI.Editor.Utils.isWindowDestroyed = function (window) {
        var doc;
        try{
            doc = window.document;
        } catch (e) {
            return true;
        }
        if (!doc) {
            return true;
        }
        return !doc.defaultView && !doc.parentWindow;
    }
 
    function fixEditor()
    {
            $find("<%=RadEditor1.ClientID %>").onParentNodeChanged();
    }
    </script>

As a small note of gratitude for reporting the issue I updated your Telerik points.
