Fluent ribbon tab item click event

I am using the Fluent Ribbon and got stuck with this problem. I have added some ribbon tab items and wanted to execute something if the user clicks on them

<Fluent:RibbonTabItem Name="TabItem" MouseLeftButtonDown="TabItem_MouseLeftButtonDown">
    <Fluent:RibbonGroupBox Header="">
        <Fluent:Button/>
        <Fluent:Button/>
    </Fluent:RibbonGroupBox>
    <Fluent:RibbonGroupBox Header="">
        <Fluent:Button Name="General" Header="General" Click="General_Click" />
    </Fluent:RibbonGroupBox>
</Fluent:RibbonTabItem>

This is a simplified part of the code... however if i click on the General button the click event fires as expected but if i click the ribbon tab item nothing happens. Here are both event handlers

 private void TabI开发者_StackOverflowtem_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        //some code        
    }

 private void General_Click(object sender, RoutedEventArgs e)
    {
        //more code           
    }

Does anyone know how to fire this event?

It's simpler than you think: the Ribbon class has a SelectedTabChanged event.

It is fired twice every time you change tab:

• the first time the System.Windows.Controls.SelectionChangedEventArgs contains the old tab in RemovedItems
• the second time it contains the new tab in AddedItems.

Both those properties are an object[].

Just look for it in the property window or let the IntelliSense find it for you ;)

Try SelectionChanged event on Ribbon Object.
