I found the Rad Editor track changes feature as useful control in telerik. As many software or finance companies have their operations going on, on each stage they would require to change their BRD, UD, Product Documents etc. to keep track of the change the editor is useful.

I would like to add some points for improvement, that we have costumized in our portal.

1) Listing of all the changes in left side of the editor (Added/ Deleted/ Replaced).

2) Can track text replacement also.

We have an issue where the RadEditor context menu for <td> element doesn't get displayed. It throws a "Permission Denied" error. Within <td> the table toolbar is not functional either. 
To reproduce: In an aspx page, create an updatepanel with a LoadContent button, RadEditor and Save button.
1. Click on Load Contents button
2. RadEditor with text "Loaded" will get displayed
3. Insert a table
4. Go to a table cell and verify context menu for td shows fine
5. Click Save
6. Go to a table cell and right click - context menu doesn't show (If you have IE developers tool, you will see "Permission Denied" error.)

ASPx page:
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <asp:UpdatePanel ID="upd" runat="server">
        <ContentTemplate>
              <asp:Button ID="btnLoad" runat="server" Text="Load Contents"  OnClick="btnLoad_Click"  />
              <telerik:RadEditor ID="HTMLEditor" runat="server"></telerik:RadEditor>          
                <asp:Button ID="btnSave" runat="server" Text="Save"  OnClick="btnSave_Click" UseSubmitBehavior="false" />
        </ContentTemplate>
    </asp:UpdatePanel>     
</asp:Content>
C# Code:
 protected void Page_Load(object sender, EventArgs e)
        {
        }
        protected void btnSave_Click(object sender, EventArgs e)
        { 
            HTMLEditor.Content = HTMLEditor.Content + " updated";            
        }
        protected void btnLoad_Click(object sender, EventArgs e)
        {
            HTMLEditor.Content = "Loaded";
        }

I recently updated my website with the dll patch telerik  provided for the cryptographic weakness:
http://www.telerik.com/support/kb/aspnet-ajax/details/cryptographic-weakness?utm_medium=email

After the update I found that the pages which were using the RadEditor control and several other controls was not loading and throwing this error:
Parser Error Message: Decryption key specified has invalid hex characters.

Several other controls are throwing this error but I cannot delete controls one by one and check which ones are having this problem.

But I checked for the RadEditor and it was throwing this error. Nothing else is there on the page while testing other than this control.
This does not happen on a plain new website and is happening when we have the sql mermbership and machine key configured. We are using passwordFormat as encrypted in sql membership config and cannot remove machine key.
If you got to test it, then test it on some already configured machine key and sql membership website.

I have attached screenshots for this error and telerik dll patch in use currently.

We are on a production server and we need a solution for this issue ASAP.

When track changes disabled the backspace is OK:
- User typed two lines (1) & (2)
- At the beginning of the line (2) user presses the backspace key, it successfully appended the line (2) with line (1) (where there was a space available). 
When track changes enabled the backspace does not work as expected:
- User typed two lines (1) & (2)
- At the beginning of the line (2) user presses the backspace key, it removes the end of the character in line (1).

How to replicate the issue

1. Using the attached document, TestSample1.docx, copy and paste the content into the RADEditor and choose to remove Word Format.

2. Observe the styling and the format of the pasted content in the editor.

You will notice that the table will not appear properly and the font styling and size and all remove instead of converted.

1.  Using the attached document, TestSample2.docx, copy and paste the content into the RADEditor and choose to remove Word Format.

2. Observe the styling and format of the pasted content in the editor.

In this case, you will notice that the table is intact and font styling and size are converted to HTML format.

The difference between the TestSample1.docx and TestSample2.docx is one has numbering in Heading. The numbering appears to have affected the result of pasted content from MS Words.
The expected behaviour would be the same as the test result from TestSample2. 

Given you have a table, where a row has multiple cells containing rowspans.

And there are also cells with no rowspan between them.

E.g. Starting HTML

<table>
    <tbody>
        <tr>
            <td rowspan="2">A1</td>
            <td>B1</td>
            <td rowspan="2">C1</td>
        </tr>
        <tr>
            <td>B2</td>
        </tr>
    </tbody>
</table>

When you delete the row (E.g. delete row 1 in the example above).

Then the cells in the resulting table are in the wrong columns.

E.g. Result HTML

<table>
    <tbody>
        <tr>
            <td>A1</td>
            <td>C1</td>
            <td>B2</td>
        </tr>
    </tbody>
</table>

Cells C1 and B2 are in the incorrect columns.

The desired outcome of deleting row 1 would be for all cells to remain in their original columns.

E.g. Desired Result HTML

<table>
    <tbody>
        <tr>
            <td>A1</td>
            <td>B2</td>
            <td>C1</td>
        </tr>
    </tbody>
</table>

Bug is reproducible in RadEditor demo using Starting HTML above (in various browsers).

ConvertWordLists errors out when pasting bullets in a nested table inside another table from Word. 

Test with the attached word doc in the https://demos.telerik.com/aspnet-ajax/editor/examples/cleaningwordformatting/defaultcs.aspx demo and you'll get the following error:

When the RenderMode property is set to Lightweight, File manager dialogs still load with Classic render mode, even when the <add key="Telerik.Web.UI.RenderMode" value="Lightweight" /> is set globally in the web.config:

<telerik:radeditor RenderMode="Lightweight" runat="server" id="mainRadEditor" EditModes="Design" >
    <Tools>
        <telerik:EditorToolGroup>
            <telerik:EditorTool Name="ImageManager"/>
            <telerik:EditorTool Name="DocumentManager"/>
        </telerik:EditorToolGroup>
    </Tools>
</telerik:radeditor>

This is causing rendering problems and some of the icons do not load.

When opening in MS Edge the Table Wizard, the items in Table Layouts tab, Select Table Style dropdown are not populated

WORKAROUND:

As a temporary workaround, you can use the attached script and loaded to the DialogsScriptFile property of the Editor:

• https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/server-side-programming/overview

<telerik:RadEditor runat="server" DialogsScriptFile="~/dialogscript.js"></telerik:RadEditor>

I know that there are articles that describe how to detect that the user has interacted with the RadEditor, but checking whether the content has changed is quite another task.
I understand that the underlying storage method makes it almost impossible to compare, but that's why we need the control to do this internally.
Even if we fall short of comparing the content, at least build-in the workarounds into the control to invoke a single "Changing" event.

RadEditor does not offer resx localization for the following Track Changes strings "Inserted by ", "Formatted by ", "Deleted by " as well as for the strings in the Comments dialog: Title, Save, Cancel and Edit.

Right now if copy multiple table rows and paste them into an existing table they create a new table in that table.  We would like the ability to copy rows from a table and paste them into the same table or a new table with the same number of columns and have the new rows pasted without the creation of a nested table.

Hello Telerik Team,

This is regarding The SpellCheck functionality in the Telerik Editor. Basically whenever a user activates the the SpellCheck from the "✓abc" button, the page automatically scrolls based on the position of the word. This does not give a good user experience and makes it difficult to work on the page. 

We have seen this issue in the demos you have on your site as well.

URL: https://demos.telerik.com/aspnet-ajax/editor/examples/spellchecker/defaultcs.aspx

To Replicate go to this URL and follow the process below: 

• Click on the "✓abc" button at the top left corner of the editor (1 In Image).
• Notice that the "Suggestion box" scroll the whole page. (2 In Image)
• Also, if you click on any other word (marked in YELLOW) in the editor, the same issue can be replicated. (3 In Image)

For your reference, we have attached a screenshot of the editor we have in our website.

Let us know if you require any further information to debug it.

Thank you,

Prateek Sanganeria

Editing the RadEditor's Tools file is rather cumbersome and error prone.

Thus, please provide an XML-Schema file that can be downloaded from the Telerik website and added to the corresponding Tools XML file header, so Visual Studio and other integrated IDEs can provide IntelliSense and error checking.

Images in a RadEditor can be resized two ways:

1. Using the image properties dialog and keying in width/height. The aspect ratio can be locked here so that keying in width updates height accordingly, and vice versa.

2. Clicking and dragging the resize handles. This does not maintain the aspect ratio of the image, even when the aspect ratio lock option is enabled in the image properties dialog.

Request: That the image aspect ratio lock option in the image properties dialog applies when dragging the resize handles.

We are using CDN and combined scripts as much as possible, and have run into an issue with the RadEditor and applying custom CSS Classes break, e.g. the applied CSS class on the selected content gets stripped for example from 

.laystyle

to

.l
