This issue happens only on Macs with Chrome and Safari.

It is related to the IME (input method editor) that is used to enter Japanese (Hiragana) words with Latin keyboards. Such an IME is provided by Windows and the Mac operating system. Part of the process to enter Japanese text is to enter several characters, then press the space bar to get a popup list of suggestions for potential words. The space bar is then pressed again until the desired word is highlighted. Then the user will press return to select the correct word. The user then presses the next characters to build the next word.

If you need more information about typing Japanese text you can find a description here: https://www.coscom.co.jp/learnjapanese801/howjpdo.html

The bug with RadEditor can be demonstrated with the current RadEditor demo page. (http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx) 

To recreate the problem you can go to your RadEditor demo page with Chrome or Safari on a Mac. You will need to enable the Japanese IME in your operating system. This is very easy to do and you can just do a Google search for instructions if you need to.

Then delete all example text. 

Now press the following keys on an English keyboard:

s a t e l o    

(each 2 key combination creates a Japanese character)

You will now see 3 Japanese characters. Now press the space bar. This will open the word selection list. Now press the space bar again, which should select the next words from the list. But instead of selecting the next word, the popup list is immediately closed and some different character are inserted in the content. If you then press another key the content gets completely destroyed and replaced with the key that was pressed. It does not work as expected and it is unusable that way.

If you try the same key sequence with Firefox on a Mac or any browser on a PC you will see how it is supposed to work.

The same problem happens if you would use the cursor down key (instead of the space bar) to select the next item in the list.

The affected browsers work as expected in regular input / textarea fields. It seems to happen only with Telerik's RadEditor control. To narrow down the cause even further I created a JSFiddle demo with a simple control that has the attribute contenteditable=true set. I believe that RadEditor is based on such a control and I wanted to see if the affected browsers may have problems with this HTML feature itself. You can try the JSFiddle demo here: https://jsfiddle.net/q5Lsnjmg/3/     The result is that the affected bowsers work as expected in this demo. This seems to indicate that the Telerik editor control must do something different to trigger this problem.

I also created a video that demonstrates the issue. You can see the video here: https://youtu.be/ANLbXpm5Zko

Hi,

Several of my clients has requested along the years for a way to insert Descriptions just beneth/under a image in the Editor, i have had to move to CKEditor in some cases and thought i would just give it a try and post this as a feature request.

A demo of this can be seen here,
http://ckeditor.com/

Think what they do is insert a Div under the image object that contains a Description.

Really hoping to see this in the future as i would like to keep third party plugins to a minimum.

A workaround is to add the following CSS rules to the DialogsCssFile stylesheet:

.reLightweightDialog.RadForm_BlackMetroTouch.redLinkManager body,
.reLightweightDialog.RadForm_Bootstrap.redLinkManager body
{
	width: 540px;
	height: 540px !important;
}

/*or use that, which will affect all skins: */
/*.reLightweightDialog.redLinkManager body
{
	width: 540px;
	height: 540px !important;
}*/

Occurs in IE11, IE10, or IE9 (Works in IE8).
Copy a table from MS word/excel into editor.
Right-click right most column.
Select Column > Delete Column.
Unable to select other rows in copied table or edit table cells

The browser becomes not responding when pasting content with a lot of span elements in IE11 in RadEditor Design view.

You can reproduce it in the following demo: http://demos.telerik.com/aspnet-ajax/editor/examples/workingwithlargecontent/defaultcs.aspx

The Properties tab in Image Manager dialog Preview tab appear as blank when custom content provider is used.

Toolbar icons are missing in Image Manager dialog when custom content provider is used

Deleting the fisrt char of a list item removes the li element instead of the char (using Delete button). 

The issue is introduced in Q1 2016.


Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
2. Insert the following content in html mode:
 <ol>
    <li>123</li>
    <li>456</li>
</ol>

3. Switch to Design mode and click in the begining of the second list item (befor 4).
4. Press the Delete key

Result:
<ol>
    <li>123456</li>
</ol>

Expected
 <ol>
    <li>123</li>
    <li>56</li>
</ol>

Pressing ENTER over a list item not only creates a new li, but also inserts additional <br> element.

Video: https://www.screencast.com/t/PZcYTKEtY4v

Steps to reproduce:
1. Open in Chrome:
2. Switch to Html mode and insert the following content:
<ol>
    <li>123 456
    <ol>
        <li>abc</li>
    </ol>
    </li>
    <li>789</li>
</ol>

3. Switch to design mode
4. Put the cursor inside the first li (e.g. before 5) and press ENTER

Result: A <br> element is added in the beginning of the new <li> element

 Out of stack space error is thrown by the Find & Replace dialog in IE11/Edge when there is an img tag withing the content. The image will cause the Find feature to sit and spin when searching for a string after the img tag. It does not return a result and it does not trigger a modal to display, e.g., “The search string was not found.”

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.

The following code will trigger the issue:
<ins author="Test user1" command="Insert" timestamp="1488935783059" title="Inserted by Test user1 on 3/7/2017, 5:16:23 PM" class="reU7">
<p cssproperty="verticalAlign" author="Test User2" timestamp="1488945891760" title="Formatted by Test User2 on 3/7/2017, 8:04:51 PM" class="reFormat reU0" command="Remove alignment"><span style="font-size: 12pt;">&nbsp;</span><span style="font-size: 12pt; font-family: 'Times New Roman';">This is some sample text.</span></p>
</ins>
When track changes are enabled and you try to delete from the end of this text, the deleted characters move to the following lines with a strikethrough rather than just deleting.

The following concerns the editing of tables within RadEditor using the out-of-the-box Delete Row and Delete Column commands:
Delete Rows:
- Click in a cell.
- Click the Delete Row button. The row is deleted.
- The Delete Row button is still enabled, but when I click it nothing happens. The cursor is in the expected location and I'm able to immediately begin typing. However, I must again click in the cell for the Delete Row button to work.

Delete Columns:
- Click in a cell.
- Click the Delete Column button. The column is deleted.
- The Delete Column button is disabled. If I begin typing or click in the table it becomes enabled and functional again.

The end-user should be able to repeatedly click either button and have it work until there aren't any more rows or columns left to delete.

There is a bug in the editor when using the image manager to insert an image after creating a new image.  This is recreated on the live demo site - http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

1. Open the image manager in the editor.
2. Click on an image editor after selecting an image.
3. Use the resizing tool to resize and save a new version of the image. 
4. Once the save is made, both images (the original and the newly created) are selected and when you click insert, both images will be inserted.

The Edit Content and other toolbar buttons are untouchable on Android Chrome on Galaxy S7, S8 and Note 5.

It is very hard to switch to edit mode and so on.

The CSS styling for copied tracked text remains after the track changes are accepted is Chrome.

Video: https://www.screencast.com/t/Ul565rfo


Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/trackchanges/defaultcs.aspx and clear the content in HTML mode
2. Switch to Design view and write some text
3. Copy this text and paste it into a new line
4. Click "Accept All track changes"

Result: The copied row remains styled as tracked text

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).
