How to pass Outlookbar SelectedItem using Caliburn Micro?

Mindscape WpfElement version: 6.0.2165.22593 Caliburn Micro version 1.5.2 VS 2010

In my ExplorerView.xaml:

<ms:OutlookBar Height="156" Margin=" Name="TaskExplorer" VerticalAlignment="Top" ExpandedItemCount="2">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="SelectedItemChanged">
                <cal:ActionMessage MethodName="ShowWorkspace">
                    <cal:Parameter Value="{Binding ElementName=TaskExplorer, Path=SelectedItem}"/>                            
                </cal:ActionMessage>
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <ms:OutlookBarItem IsSelected="True" x:Name="Mfg">
            <ms:OutlookBarItem.Header>
                <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" Margin="5,0,0,0" Height="25">
                    <TextBlock Margin="13,0,0,0" FontWeight="Bold" VerticalAlignment="Center" HorizontalAlignment="Left"
                     Foreground="Black">Manufacturing</TextBlock>
                </StackPanel>
            </ms:OutlookBarItem.Header>
            <StackPanel>
                <CheckBox Content="Test"/>
            </StackPanel>
        </ms:OutlookBarItem>

        <ms:OutlookBarItem x:Name="Setting">
            <ms:OutlookBarItem.Header>
                <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" Margin="5,0,0,0" Height="25">
                    <TextBlock Margin="10,0,0,0" FontWeight="Bold" VerticalAlignment="Center" HorizontalAlignment="Left"
                     Foreground="Black">Setting</TextBlock>
                </StackPanel>
            </ms:OutlookBarItem.Header>
            <TextBlock VerticalAlignment="Top" Text="Calendar123" />
        </ms:OutlookBarItem>
    </ms:OutlookBar>

In my ExplorerViewModel:

    public void ShowWorkspace(object selectedItem)
    {
    }

When call into ShowWorkspace method, selectedItem is null. Have i missed out anything?

Hello

The binding was not working because our SelectedItem property was not a dependency property. I've updated this which you can get from the next nightly build. (About 12 hours from now) http://www.mindscapehq.com/products/wpfelements/nightly-builds Sorry for any inconvenience.

Hi Jason,

Thanks for the respond. On second thought, it would probably be better to pass the SelectedIndex property instead of SelectedItem. Is this property available?

Hello

I agree, it would be much better to have the selected index so that you don't pass UI controls into the model layer. I've added the SelectedIndex property for you which will be available in the next nightly build.
