        var value = args.get_value();
 
        if (commandName == "Paste" && Telerik.Web.Browser.ie) {

By default all options "Copy Format", "Apply Format" and "Clear Format" are all enabled when a ribbonbar toolbar is used, but the second and third options should be disabled initially. 

The problem does not happen in the Default toolbar mode and can be reproduced in the Overview demo of the control -> switch to ribbonbar mode and press the full set of tools radio button. The Clear format tool is located in the sixth button group of the ribbonbar.

Hi Team,
Is there any way to set the MaxTemplateSize,MaxFlashSize,MaxMediaSize,MaxDocumentSize,MaxTemplateSizes from the web.config itself without any code change. currently my system taking the default value "200KB". please let me know is there any way, in asp.net Ajax RadEditor in Asp.net C#. We are using telerik dll version 2017.1.228.45.

When using the Microsoft Edge browser with the Editor, you cannot add field values for some form elements. This seems to affect Radio buttons and checkboxes. It is possible that it affects other form elements as well. I also see this same problem when using your demo page https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx.

Edge does not offer the hasLayout capability of Internet Explorer, which selects the form element on click. In Edge you can select a form element as you could do it with a text: https://www.screencast.com/t/mo25Rm1kTSdB. The click selection is not currently supported.

Steps to reproduce:
1. Go to the Editor demo page in Chrome
2. CTRL+A on the editor and hit delete
3. Hit Delete or Backspace again
Result: Uncaught TypeError Appears in the console

Steps to Reproduce:
1. Insert a table and add some data to the table in Chrome
2. Above the Table, insert some text
3. Highlight the text and drag cursor to highlight half of the data in the table
4. Hit Delete on your keyboard

Result: The colgroup is removed from the table

Position the cursor between the words SharePoint and Whether in the first paragraph and add a line break, after that press Backspace and you'll see that the new line does not disappear.

Adding new sections between existing paragraphs or after the last paragraph seems to work fine, but if you have to break up an existing paragraph into two paragraphs and then want to turn it back into one you won't be able to.

I have a RadEditor that is rendered in mobile mode on a mobile device emulator in Chrome browser.
For this editor, I have subscribed to OnClientCommandExecuted event. The event fires, but the problem is that it fires twice for ToggleScreenMode command.
To reproduce this issue, you can use the page code below and render it in Chrome mobile emulator; then press on edit pencil button followed by clicking the check button.

OnClientModeChange event is not fired in Mobile RenderMode.

Steps to reproduce:
Run the following code in a mobile Chrome (or mobile emulation) and click the edit Pencil button that switches the edit modes:

        <script type="text/javascript">
            function OnClientModeChange(editor, args) {
                var mode = editor.get_mode();
                switch (mode) {
                    case 1:
                        alert("We are in Design mode");
                        //do something
                        break;
                    case 2:
                        alert("We are in Html mode");
                        //do something
                        break;
                    case 4:
                        alert("We are in Preview mode");
                        //do something
                        break;
                }
            }
        </script>

        <telerik:RadEditor runat="server" OnClientModeChange="OnClientModeChange" ID="RadEditor1" RenderMode="Auto">
        </telerik:RadEditor>

When RadEditor is configured with RenderMode="Auto", it renders fine on a mobile, but the Find and Replace throws a JavaScript error:

Render mode configuration in the web.config

<add key="Telerik.Web.UI.RenderMode" value="Auto" />
It seems, code is looking for FindAndReplace key in this._dialogDefinitions, but it's not there. However, the key FindAndReplaceSettings is there.

The Delete and Backspace buttons remain enabled in spell check mode, allowing the client to delete selections inside the Editor's content area.

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/spellchecker/defaultcs.aspx
2. Click the Spell check icon
3. Select several words from the content and press Backspace/Delete

Result: The selected content is deleted
Expected: The Delete/Backspace button press is ignored

The Bold, Italic, Underline, Justify, Indent, Outdent and other commands are not localized in the Undo/Redo dropdowns.

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.)

When the fore/backcolor of the Editor is changed through its toolbar, the same color is set to all Editors on the page. The problem is reproducible in Lightweight rendering.

Clear content;
Add a table;
Open context menu by selecting a cell in the table;
Open Cell Properties;
Open More cell Styling;
Chose Background color;
Change it and click OK
Click OK in Table Wizard.
Actual: No background color is applied. 

Even if the ToolsFile is pointing to a valid file, no toolbar is rendered when the control is loaded in a mobile browser.

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.
