+## Description
+Even after setting `enableEditing` and `set_editable` to `false`, it's still possible to remove or modify the content in RadEditor using the backspace key. How can this behavior be disabled to prevent content removal?
+
+This KB article also answers the following questions:
+- How to make RadEditor content non-editable?
+- How to disable the backspace key in RadEditor?
+- How to prevent content modification in RadEditor?
+
+## Solution
+To prevent users from removing content using the backspace key in [RadEditor](https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/overview) while keeping the editor non-editable, follow the steps below:
+
+1. **Disable Editing and Make Non-Editable:**
+
+   Set the editor to non-editable mode by using the `enableEditing(false)` and `set_editable(false)` methods.
+
+2. **Disable the Backspace Key:**
+
+   Add an event listener to the RadEditor content area to disable the backspace key functionality.
+
+   ````ASPX
+   <script>
+   function OnClientLoad(editor, args) {
+       editor.enableEditing(false);
+       editor.set_editable(false);
+
+       var contentArea = editor.get_contentArea();
+       contentArea.addEventListener('keydown', function (e) {
+           if (e.key === 'Backspace') {
+               e.preventDefault();
+           }
+       });
+   }
+   </script>
+   ````
+
+3. **Integrate the Event Listener with the RadEditor:**
+
+   Ensure the `OnClientLoad` event is properly configured in your RadEditor definition.
+
+   ````aspx
+   <telerik:RadEditor ID="RadEditor1" runat="server" OnClientLoad="OnClientLoad">
+       <Content>some content</Content>
+   </telerik:RadEditor>
+   ````
+
+   This configuration disables the backspace key, preventing content removal and modification, while keeping the editor in a non-editable state.
+
+Additionally, to disable other editing features such as copy, typing, enter, delete, and pasting content, you can use the `OnClientCommandExecuting` and `OnClientPasteHtml` events:
+
+```asp
+<telerik:RadEditor runat="server" ID="RadEditor1" ContentAreaMode="iframe" OnClientLoad="OnClientLoad" OnClientCommandExecuting="OnClientCommandExecuting" OnClientPasteHtml="OnClientPasteHtml">
+    <Content>test content</Content>
+</telerik:RadEditor>
+```
+
+````ASPX
+<script>
+function OnClientCommandExecuting(editor, args) {
+    args.set_cancel(true);
+}
+function OnClientPasteHtml(editor, args) {
+    args.set_cancel(true);
+}
+</script>
+````
