Can anybody help with why the following will not display a vertical

but the following does?

I recently wanted to add "headers" to my ListBox and was able to do so thanks to the following post:

http://www.telerik.com/forums/can-a-listbox-have-headers

However, now I haven't been able to have the entries in the listbox refresh when the underlying data changes. It seemed to work just find before the "headers" were added. I have attached the original code when the data binding seemed to work fine:

and the code where the headers works fine (but data binding doesn't seem to work when the data changes...):

Hi all,

  I implement row drag drop function, I got a demo source code in somewhere forum(), the problem is:

In demo source code, Telerik tersion is 2009.1.526.35, below code works OK

But currently my solution uses a newer Telerik version, 2014.1.331.40, RadItemsControl could not be found. 

How can I find the similar control to replace the old one? Or any idea to get current drop index here?

 Thanks.

I'm using a simple RadMenu and I am having a bit of trouble getting it to look correctly in the application.

It seems to be adding a small padding area to the surrounding the first menu item. (I've attached an image of how it renders in the application)

Here is the XAML: 

Also, I don't want the arrow icon to appear, but I don't seem to be able to get rid of it.

I'm using the Windows8Touch theme.

Any help would be appreciated.

I'm looking for a way to change the background of the title bar of a RadWindow.Alert.

I'm looking to mimic the affect that line one has on the title bar without changing the accent color for ALL items.

Ideally, I'd like to be able to pass in the Colors.Red or set a Style Resource somewhere.

Hi, 

We are using RadMenu on a  solution with wpf and telerik on this way:

Here is the element menu: 

 <telerik:RadMenu x:Name="MenuPrincipal" ItemsSource="{Binding MenuItems}"                         
                         ItemContainerStyle="{StaticResource MenuItemStyle}" >  </telerik:RadMenu> 

Styles:

 <UserControl.Resources>
            <Style x:Key="MenuItemStyle" TargetType="telerik:RadMenuItem">
                <Setter Property="Command" Value="{Binding Command}" />
                <Setter Property="CommandParameter" Value="{Binding CommandParameter}" />
                <Setter Property="Header" Value="{Binding Header}" />
                <Setter Property="ItemsSource" Value="{Binding Items}"/>
                <Setter Property="IsSeparator" Value="{Binding IsSeparator}"/>                              
        </Style>           
    </UserControl.Resources>

The item collection are generated like a ObservableCollection of our own class with header, subitems, and everything it´s working fine. The Menu it´s appearing ok on the screen and showing correctly the childs and parents. The relation between parents and childs inside the RadMenu Items are working fine :)

The problem is... now, i need to add a RadContextMenu on some items of the menu, and i don´t know how to do it. I´m trying to do on several ways, but nothing it´s working properly.

First try:

 <telerik:RadMenu x:Name="MenuPrincipal" VerticalAlignment="Top"  ItemsSource="{Binding MenuItems}"                         
                         ItemContainerStyle="{StaticResource MenuItemStyle}" >                      
                  <telerik:RadMenu.ItemTemplate >
                            <DataTemplate>
                                     <telerik:RadMenuItem Header="{Binding}" ContextMenuOpening="RadMenuItem_ContextMenuOpening" >
                                              <telerik:RadContextMenu.ContextMenu>
                                                <telerik:RadContextMenu>                                                
                                                    <telerik:RadMenuItem Header="{Binding }"/>
                                                </telerik:RadContextMenu>
                                            </telerik:RadContextMenu.ContextMenu>                            
                                    </telerik:RadMenuItem>   
                            </DataTemplate>
                 </telerik:RadMenu.ItemTemplate>-->
            </telerik:RadMenu>

That way, creates the menu item like a button (with a border...) and it´s not responding on click. (If i click outside the border the menu displays). I can Solve with "autoopen", but in that way, when the context menu has showed, the menu closes, also whit "stayopen" property enabled. 

Second Try

With codebehind - Trying to add a RadContextMenu on our own class of the menu and binding on  that way <Setter Property="ContextMenu" Value="{Binding ContextMenu}"/> Not succesfull :( 

Also to consider. I need to show the menu only in the final childs, not in the parent menus... 

Any help will be appreciated. 

Thank you, regards.
