Using MVVM light toolkit with Menuitem
posted

Hi,

We are using t he MVVM light toolkit and want to attach a command to a menu item.

I've created the following XAML the event doesn't appear to be triggered.

Does anyone have any pointers?

Many thanks,

<ig:XamMenuItem Header="New" Height="33" HorizontalAlignment="Left"  Name="xamMenuItem1" VerticalAlignment="Center"  >
                <i:Interaction.Triggers>
                    <i:EventTrigger EventName="Click">
                        <cmd:EventToCommand Command="{Binding NewContactCommand, Mode=TwoWay}" />
                    </i:EventTrigger>
                </i:Interaction.Triggers>
</ig:XamMenuItem>

    Hi,

    I've had the same problem and fixed it.  It seems the XamMenuItem isn't aware of it's DataContext.  Try setting the data context on the XamMenuItem.  Here is my example:

     

     

                              <ig:XamMenuItem

                                    DataContext="{Binding RelatedPriorityGrid, Source={StaticResource Locator}}" 

                                    Name="AddPriority" 

                                    Header="Ajouter item sélectionné à mes priorités"

                                    IsEnabled="{Binding CanAddPriority}">

                                    <i:Interaction.Triggers>

                                        <i:EventTrigger EventName="Click">

                                            <cmd:EventToCommand PassEventArgsToCommand="True" Command="{Binding AddPriorityCommand}" />

                                        </i:EventTrigger>

                                    </i:Interaction.Triggers>

                                    <ig:XamMenuItem.Icon>

                                        <Image Source="Resources/Add.png"/>

                                    </ig:XamMenuItem.Icon>

                                </ig:XamMenuItem>

     

     

    Hope this helps!
