Paste operation causes IE6 to close using the editor contextmenu

[Bong]

Hi,

I'm having trouble using IE6 when the Paste command is executed through the context menu but using the shortcut key CTRL+V works well and sees no problem with it. This problem occurs in all of our machines which have an IE6 installed including my development machine.I've tested this in Windows XP SP2 and Windows XP SP3. I'm using Telerik Version 2010.

To repro:
1. Copy an item(text/word)
2. Select a text in the editor (highlight a text)
3. Paste the copied content in the selected text through context menu

Do this several times(step 2-3)


Thank you and best regards,
Bong

Hi,

This is not only happened in paste operation but all commands in the context menu. For example execute copy command multiple times causes IE6 to crash.

Thank you and best regards,

Hi Bong,

Can you please make sure that all IE6 latest updated are installed on the problematic machine? If they are and the problem still persists my recommendation is to disable the built-in context menus of RadEditor in IE6 using the code below:

<script type="text/javascript">
    function OnClientLoad(editor) {
        editor.get_toolAdapter().enableContextMenus(false);

//      editor.attachEventHandler("contextmenu", function(e) {
//            //Get a reference to the element for which the user clicked the context menu
//            target = e.target ? e.target : e.srcElement;
//            $telerik.cancelRawEvent(e);
//        });

    }
</script>
<telerik:RadEditor ID="RadEditor" OnClientLoad="OnClientLoad" runat="server"/>

If the problem is reproducible even with the IE6 browser's contextmenu then disable it using the commented code.

You can check for the IE6 browser using if ($telerik.isIE6).

Hi Rumen,

I already installed the latest update for windows xp and ie6 in our machines but still the problem exists in IE6. It's also impossible for me to disable the context menu in the editor since it is one of the requirements, besides majority of our users has IE6 installed. I just want to know if this is a bug in the editor or is there something wrong that I'm missing? Also I cannot find ways to handle the exception.


Thank you and best regards,

Hello Bong,

I tried to reproduce the problem, but I was unable to crash my test IE6. You can see my test in the following video: http://screencast.com/t/HjFEKXPgju7.

The only suggestions except disabling the built-in context menus of RadEditor is to set the StripFormattingOptions property to "NoneSupressCleanMessage", therefore RadEditor will not alter the pasted content and this could fix the problem.

By the way, if you disable the built-in context menus, the browser context menu will work. It contains the same Cut, Copy and Paste options as the RadEditor's context menus.

Hi Rumen,

I already set StripFormattingOptions="NoneSupressCleanMessage" but still the problem exists. I've seen the video and I expected that no error will occur since the confirmation message probably trap the error. Indeed, when I add OnClientPasteHtml event in the editor and put an alert message in it, the problem doesn't occur. By the way, it's not only the PASTE that produces the error but also the other context commands including CUT and COPY.

As I've said before, I can't afford to disable the context menu since it's not only the text operation that we need there but also some other commands.

Thank you and best regards,
Bong

Hi Bong,

I tested the editor with the following configuration:

<telerik:RadEditor ID="RadEditor1" runat="server" StripFormattingOptions="NoneSupressCleanMessage">
 <Content>The quick brown fox jumps over the lazy dog</Content>
</telerik:RadEditor>

and I was unable to reproduce the problem in IE6 again. Here is my test: http://screencast.com/t/wWrafAVBMa. For your convenience I have attached my test project.

If you are able to reproduce the problem with the project, please set the ContentAreaMode="Div" property and test again.
