RadEditor Toolbar rendering issue IE9

[Rudy]

Hi, as attached you will see some strange behaviour of the radeditor in IE9.
As you will see, the toolbar is rendered as a bulleted list, but i have no custom skin or css added, that uses OL or UL styling tags

The same page works in Chrome, Firefox and IE10

Do you have some idea it could be? Does it have something to do with a css that i don't know off or what?


This is the markup:

<telerik:RadEditor ID="DescriptionTextBox" runat="server">

     <Content>

                    MyContent

     </Content>

 </telerik:RadEditor>

Thx

Hi Rumen,
as i mentioned today, the radeditor toolbars are rendering ok, but when i exit the page, an error is loged by my system that i had overseen this morning.

Like i said, in my page i added:

<telerik:RadStyleSheetManager ID="SSH1" EnableStyleSheetCombine="true" runat="server">

<StyleSheets>

<telerik:StyleSheetReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Skins.Editor.css" />

<telerik:StyleSheetReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Skins.Default.Editor.Default.css" />

<telerik:StyleSheetReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Skins.Window.css" />

<telerik:StyleSheetReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Skins.Default.Window.Default.css" />

</StyleSheets>

</telerik:RadStyleSheetManager>

When i exit the page an execption !
What did i forgot to add?

Thx
Rudy

Hello Rudy,

I am not able to reproduce this issue on our side. Could you send me a step by step instructions and  some sample code, which I can use to reproduce the behavior? Once I receive this additional information I will be able to help you further.

Greetings,

Sorry for the late reply, but it's to difficult to post our code, when i isolate the problem it does not happen, but in combination of our software it fails.
We made another decision so the problem is now "gone" (for now :) )
Thanks for the help.
