Bug report

When uploading a file through the Editor's FileBrowser, the file's name is not updated with the name coming generated on the server. The file's name is updated in the ImageBrowser using the same server code.

Editor configuration:

$("#editor").kendoEditor({               
                fileBrowser: {
                    schema: {

### Bug report

A non-breaking space is added at the beginning of each new row when typing in the Editor.  As a result, the method "getRange" returns a wrong "startOffset" index.

### Reproduction of the problem

    1. Subscribe to the "select" event of the Editor;

    2. Log the property "startOffset" of the "getRange" method in the browser console;

    3. Click on any line in the empty Editor and check the logged index. It is "1" instead of "0".

    4. Type in any text in the Editor and click at the beginning of the text - the logged index is "1" instead of "0".

A Dojo sample for reproduction: https://dojo.telerik.com/UqUNoBaM/8

### Expected/desired behavior

The non-breaking space should be removed when typing.

  2. Input some text
  3. Make it bold and underline
  4. Make it bulleted
  5. Add few more bullets
  6. Select all bullets
  7. Press backspace

Observe that two bullet points remain

Hi,

 

We are facing an issue as follows.

1. We type some ordered or unordered list and we move cursor one left or right.

2. We do select all and backspace to delete entire list.

 

Issue: First index or bullet never gets deleted does not matter how many times backspace is clicked. On inspecting dom we can see list structure is retained and does not get deleted.

 

Please find attached video.

 

Thanks

Bug report

When setting a special font of a given paragraph in the Editor component, if the "x" of the Font dropdown is pressed it will reset the font of this text to the default one. If we then want to change the format of a given paragraph(make it bold for example), we select the paragraph and click on the "Bold" button. The text which is being bolded is the one which font was previously reset, not the selected text which we expect to become bold.

Reproduction of the problem

  1. Open this Dojo and select a random text in the Editor
  2. Change the font of the selected text by choosing one from the "Fonts" dropdown
  3. After changing the font keep the text selection and click on the "x" in the "Fonts" dropdown. The font of the selected paragraph will be reset to the default one.
  4. Select a random text chunk in the Editor and click on the "Bold" button.
  5. See that the bolded text is not the one we expect to be, but the text which font we've reset.

The reported behavior is applicable to all styles - bold, italic, underline, text alignment, ul, ol.

Current behavior

When changing the style of a given selected text, after there was a font reset in the Editor, the new formatting we set is being applied on the text which font was reset, not on the selected one.

Expected/desired behavior

No matter the operations performed in the Editor when formatting a selected text, the format changes should be applied to the selected text only.

Description of the occurring behavior

the styling of links is handled inconsistently:

  • When you set the cursor inside a link and then change the text-color the color is changed.
  • When you select a block of text containing a link and style the entire block of text (e.g. change the color) and then you try to change the color of the link this has no effect.

The issue seems to be that in the first case a span is inserted inside the a-tag, while in the second case a span is created around the a-tag and the styling for the a-tag is then used.

Reproduction of the problem

This can be reproduced in the All Tools demo as shown in the following video.

NOTE: if only the link is selected, or the selection starts or ends with the link, then the link color is changed. The issue is reproducible only when there is selected text before and after the link.

Expected/desired behavior

The color should be applied to the link text too.

Bug report

Using Edge/Chrome, upon pasting underline text in the Kendo UI Editor, the content is rendered underline, but the UI doesn't highlight the button. In turn, if the user toggles the underline style for parts of the text, it doesn't work. At this point, the button is now highlighted for the part, but switching back to no underline style doesn't have any effect regarding the rendering. Removing the style for the whole line does work as expected.

Reproduction of the problem

  1. Open Editor demo and enter some text, containing an underline.

UnderlineTextStep1

  1. Copy the entered text and reload page
  2. Paste content at the start of the document. The text is not recognized as underline text

UnderlineTextStep3

  1. Select part of the text and toggle underline. Part of the text is recognized as underlined text now.

UnderlineTextStep4A
UnderlineTextStep4B

Expected/desired behavior

The underlined text decoration should be recognized by the UI and display.

Additional Notes

As a comparison, here is the content after paste:

Edge/Chrome

<p><span style="text-decoration-line:underline;">some text with underline</span></p>

FireFox - which is working

<p><span style="text-decoration:underline;">some text with underline</span></p>

Currently, Kendo UI for jQuery components rely on innerHTML and direct DOM manipulation throughout their internal implementation. This occurs in multiple components.

Thus, when "require-trusted-types-for 'script';" is included, errors such as - `This document requires 'TrustedHTML' assignment. The action has been blocked.` and `TypeError: Failed to execute 'write' on 'Document': This document requires 'TrustedHTML'`appears on the page.

I would like to request Trusted Types Support for Kendo UI for jQuery components.
