Hi,

I am trying to use several radcontextmenu on same xaml page. And graphically it works fine . But on my output I have serveral errors  :

 

 
System.Windows.Data Error: 4 : Cannot find source for binding with reference   
'RelativeSource FindAncestor,   
AncestorType='Telerik.Windows.Controls.RadContextMenu'AncestorLevel='1''.   
BindingExpression:Path=DataContext.SelectIrisV2CodesCommand; DataItem=null;   
target element is 'EventToCommand' (HashCode=11696593); target property is   
'Command' (type 'ICommand')


This error happens when i open successively two different radcontextmenu.
Scenario :
- The first radcontextMenu clicked on, contains only leaves
- The second radcnctextMenu clicked on, contains on first level only root nodes (Role = Submenuheader?)

Below the code of my page :

 

 

<Style x:Key="IrisRadMenuItemStyle" TargetType="{x:Type telerik:RadMenuItem}">   
     <Setter Property="Template">   
        <Setter.Value> 
            <ControlTemplate TargetType="{x:Type telerik:RadMenuItem}">   
                <Grid x:Name="RootElement" Background="{TemplateBinding Background}" Margin="2" >   
                    <i:Interaction.Triggers>   
                        <i:EventTrigger EventName="MouseLeftButtonDown">   
                            <cmd:EventToCommand Command="{Binding DataContext.SelectIrisV2CodesCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerikNavigation:RadContextMenu}}, Mode=OneWay}" CommandParameter="{Binding}" />   
                        </i:EventTrigger>   
                    </i:Interaction.Triggers> 
                        ...   
 
         </Setter.Value>   
    </Setter>   
    <Style.Triggers>   
        <Trigger Property="Role" Value="SubmenuHeader">   
            <Setter Property="Template">   
 
                <Setter.Value>   
                    <ControlTemplate TargetType="{x:Type telerik:RadMenuItem}">   
                    <Grid x:Name="RootElement" Background="{TemplateBinding Background}" Margin="2">   
                    <i:Interaction.Triggers> 
                        <i:EventTrigger EventName="MouseEnter">   
                            <cmd:EventToCommand Command="{Binding DataContext.ShowIrisCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerikNavigation:RadContextMenu}}, Mode=OneWay}" CommandParameter="{Binding}" />   
 
                        </i:EventTrigger>   
                    </i:Interaction.Triggers> 
                    ...  
        </Trigger>   
    </Style.Triggers>   
</Style>   
 
<ToggleButton Grid.Row="1" Grid.Column="2" Width="20" IsChecked="{Binding IsOpen, ElementName=Nav, Mode=TwoWay}">  
    <telerikNavigation:RadContextMenu.ContextMenu > 
        <telerikNavigation:RadContextMenu EventName="MouseLeftButtonDown" Name="Nav"   
ItemContainerStyle="{DynamicResource IrisRadMenuItemStyle}" Style="{DynamicResource IrisRadContextMenuStyle}" ItemsSource="{Binding IrisCodes}" >   
 
            <telerikNavigation:RadContextMenu.ItemTemplate>   
                <HierarchicalDataTemplate ItemsSource="{Binding IrisCodes}" />   
            </telerikNavigation:RadContextMenu.ItemTemplate>   
        </telerikNavigation:RadContextMenu>   
    </telerikNavigation:RadContextMenu.ContextMenu>   
    <Image Source="/Solmis.Client;component/Images/16/view.png" />   
</ToggleButton>   
 
 
...  
 
 
<ToggleButton Grid.Row="2" Grid.Column="2" Width="20" IsChecked="{Binding IsOpen, ElementName=NavCOE, Mode=TwoWay}">   
    <telerikNavigation:RadContextMenu.ContextMenu >   
        <telerikNavigation:RadContextMenu EventName="MouseLeftButtonDown" Name="NavCOE"   
ItemContainerStyle="{DynamicResource IrisRadMenuItemStyle}" Style="{DynamicResource IrisRadContextMenuStyle}" ItemsSource="{Binding IrisCodes}" >   
 
            <telerikNavigation:RadContextMenu.ItemTemplate>   
                <HierarchicalDataTemplate ItemsSource="{Binding IrisCodes}" />   
            </telerikNavigation:RadContextMenu.ItemTemplate>   
        </telerikNavigation:RadContextMenu>   
    </telerikNavigation:RadContextMenu.ContextMenu>   
 
    <Image Source="/Solmis.Client;component/Images/16/view.png" />   
 
</ToggleButton> 

 

 

 


It seams there is only one instance of RadContextMenu for all RadContextMenu i have in my page.. If it's the case, i would know why the role=sumbmenuheader style is also applied on leaves ?

Thank you in advance for your help

 It will be better to use our support system since attachments in forums are size (and content) limited.
