RadContextMenu Scrollbar not working

[Robert]

Hi, I've followed the instructions as per the following article > http://www.telerik.com/help/silverlight/radcontextmenu-how-to-add-scrolling-to-radcontextmenu.html

However, I can't get the scrollviewer to appear on the root context menu. Can someone please help me create a sample project with the style set for a scrollviewer? I can't attach a zip to this post, but all I did was add a context menu to a blank page, wrap the 2 (? the article says there should be 4 I think) ItemsPresenters in the generated code with a ScrollViewer. It works for the flyout menus, just not the root menu.

Thanks,
-Robert

I'm getting ready to scrap the RadContextMenu completely. The sample does not work, or is incomplete from http://www.telerik.com/help/silverlight/radcontextmenu-how-to-add-scrolling-to-radcontextmenu.html.

Should I file a Bug report? It would be nice if the Telerik context menu rendered a Scrollbar automatically based on the height of the rendered Silverlight application. I'm dealing with some space restrictions Vertically, and a menu that does not fit. I've wasted a lot of time on the sample provided in your knowledgebase.

Hi Robert,

Sorry for the omission in the help article.

In order to add a ScrollBar to the root level item you need to generate and edit the template of the ContextMenu itself. Please find attached a sample application in which this is illustrated.

Please let us know if you have further questions.

All the best,

Hello Konstantina  ,
I've tried the demo you provided on a WPF application but I got a weird problem... if I leave the ItemContainerStyle="{StaticResource RadMenuItemStyle}" I got the problem in the image I've attached (I don't see the submenu of item 1/2)

If I comment it out I got them but I don't have the scrollbar on the submenu

if you want try to put this code 

<telerik:RadContextMenu.ContextMenu>
            <telerik:RadContextMenu HorizontalAlignment="Left" VerticalAlignment="Top"  ItemContainerStyle="{StaticResource RadMenuItemStyle}"
                                    Style="{StaticResource RadContextMenuStyle}">
                <!--Opened="RadContextMenu_Opened"  -->
                <telerik:RadMenuItem Header="Item 1">
                    <telerik:RadMenuItem Header="Sub Item 1"/>
                    <telerik:RadMenuItem Header="Sub Item 2"/>
                </telerik:RadMenuItem>
                <telerik:RadMenuItem Header="Item 2">
                    <telerik:RadMenuItem Header="Sub Item 3"/>
                    <telerik:RadMenuItem Header="Sub Item 4"/>
                    <telerik:RadMenuItem Header="Sub Item 5"/>
                    <telerik:RadMenuItem Header="Sub Item 3"/>
                    <telerik:RadMenuItem Header="Sub Item 4"/>

Hello Paolo,

Did you use the xaml code of the RadContextMenu for WPF, which can be found in the installation folder of Telerik components on your computer? If so, could you please send it here, so that we can review it - seems that the style is not correct and it is not applying.
