Hi.
I'm using radmenu like this:
<telerik:RadMenu Grid.Column="0" VerticalAlignment="Center" IsTabStop="False" Orientation="Vertical">
    <telerik:RadMenu.Items>
        <telerik:RadMenuItem Header="Modyfikuj" Command="{Binding Path=StartEditPartCommand}"/>
        <telerik:RadMenuItem Header="Zatwierdź" Command="{Binding Path=CommitEditPartCommand}"/>
        <telerik:RadMenuItem Header="Anuluj" Command="{Binding Path=RejectEditPartCommand}"/>
    </telerik:RadMenu.Items>
</telerik:RadMenu>

so basically, i'm binding menu items to some commands which have canexecute method:
StartEditPartCommand = new DelegateCommand(
    /*foo*/,
    () => !IsEditingPart && SelectedItem != null);


somewhere in code, raisecanexecutechanged method is properly raised:
StartEditPartCommand.RaiseCanExecuteChanged();

and... it doesn't refresh menuitems' IsEnabled property - they remain in previous state. Sliding mouse cursor over menuitem causes menuitems refresh, but not always.

When having changed radmenu to itemscontrols/stackpanels with buttons everything works fine, so it's probably bug with radmenu or radmenuitem?

Hello,

I will paste the answer from the support ticket as well:

We tested the scenario and we can confirm that this bug is already fixed in our latest internal build.

Kind regards,

I have problem with MenuItem too.

<Style x:Key="MenuItemStyle">
   <Setter Property="MenuItem.Header" Value="{Binding Caption}"/>
   <Setter Property="MenuItem.ItemsSource" Value="{Binding Items}"/>
   <Setter Property="MenuItem.Command" Value="{Binding Command}" />
   <Setter Property="MenuItem.CommandParameter" Value="{Binding ViewModel}" />
</Style>

When I use standard menu in WPF it works. And commands opens new tile in my app.
<Menu x:Name="mnAdmin" IsMainMenu="True" DockPanel.Dock="Top">
    <MenuItem Header="_Admin" ItemsSource="{Binding CisMenu.Items}"  ItemContainerStyle="{StaticResource MenuItemStyle}"/>
</Menu>

But when I use this code. It doesn't works.
<telerik:RadMenu x:Name="mnAdmin" DockPanel.Dock="Top" >
   <telerik:RadMenuItem  Header="_Admin" ItemsSource="{Binding CisMenu.Items}"  ItemContainerStyle="{StaticResource MenuItemStyle}" />
</telerik:RadMenu>

It it same bug with you wrote above?

Hello,

What I would suggest is targeting the RadMenuItem, not MenuItem in the Style setters. This should do the trick.
