I have 2 editors. The first has Design and Preview modes enabled. When I switch from Design to Preview mode the toolbars are disabled. This is a good thing.

On the other editor, I only have Preview mode enabled and the toolbars here are enabled. Why is this different from the other editor?

Hi Stuart,

We are not aware of such problem and you are the first one to report it. I tried to reproduce the problem on my side but to no avail.

Could you please open a support ticket and provide a sample project reproducing the problem so we can investigate it further?

On a side note, is any JavaScript error thrown on the page during load? If so, this might interrupt of the further execution of the JavaScript code related to the disabling of the toolbar of the second editor.

Dobromir ,

Sorry, my bad. I neglected to mention something; the editors are in RadPageView controls.

Below is a standalone page that demonstrates the problem...
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %>

          </telerik:RadEditor>
        </telerik:RadPageView>
      </telerik:RadMultiPage>
    </form>
  </body>
</html>

For the sake of completion, I've included 3 screen shots; ss1 shows the fist editor in Design mode, ss2 the same editor in Preview mode and the ss3 the 2nd editor in Preview mode.

Dobromir,

I forgot to mention that there is no evidence of any JS errors when the page executes.

Hmmm. This is interesting...

If I edit the markup so the the "History" tab is initially selected the toolbars on the editor are correctly disabled.

Hi Stuart,

Thank you for the additional information and the sample page. This problem occurs when the RadEditor is placed in initially invisible parent. You can use the following approach to avoid this issue:
<telerik:RadTabStrip ID="RadTabStrip1" runat="server" MultiPageID="RadMultiPage1"
    SelectedIndex="0" OnClientTabSelected="OnClientTabSelected">
    <Tabs>
        <telerik:RadTab Value="edit" Text="Edit" />
        <telerik:RadTab Value="history" Text="History" />
    </Tabs>
</telerik:RadTabStrip>
 
...........
...........
 
<script type="text/javascript">
    function OnClientTabSelected(sender, args)
    {
        if (args.get_tab().get_index() == "1")//check if the selected tab is the one containing the correct editor
        {
            setTimeout(function ()
            {
                var editor = $find("<%= edtHistory.ClientID %>");//get reference to the editor
                editor.set_editable(false);
                editor.enableEditing(false);
            }, 0);
        }
    }
</script>
