How do I bubble an event from a user control up to window it is contained in?

Question

I have a user control with a search bar and a search button that I am displaying in a window. On the button click I want the event to bubble up to the window where I can do stuff in the window's code behind. I don't want to put the button click code in the user control code behind. How do I do this?

The xaml for the Window looks like this:

<dx:DXWindow
x:Class="Client.Support.AskAQuestionDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core"
xmlns:libRes="clr-namespace:Shared.Lib.Resources;assembly=Shared.Lib"
xmlns:support="clr-namespace:Client.Support"
xmlns:gui="clr-namespace:Client.GUI;assembly=Client.GUI"
Title="{x:Static libRes:Strings.AskAQuestion}" Loaded="DXWindow_Loaded" 
Height="150" Width="700">

<Grid>
    <Viewbox>
        <support:ZenForumSearchBar VerticalAlignment="Center" HorizontalAlignment="Center"/>
    </Viewbox>
</Grid>
</dx:DXWindow>

In the code behind for the UserControl I have this code for the Click event

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        RaiseEvent(e);
    }

And in the window that contains the user control I tried to make a handler to handle the event like this

    private void ButtonHandler(object sender, RoutedEventArgs e)
    {
        FrameworkElement fe = e.Source as FrameworkElement;
        switch (fe.Name)
        {
            case "_knowledgeBaseSearchButton":
                break;
        }
        e.Handled = true;
    }

I think I am doing everything completely wrong though. How do I get the event that happens in the UserControl to bubble up to the Window where it got instantiated?

Answer 1

Button.Click is already bubbling event so you don't need Button_Click in your UserControl. All you need to do is attach handler in you Window, Grid or ViewBox

<Grid Button.Click="ButtonHandler">

and in the handler check e.OriginalSource instead of e.Source

var fe = e.OriginalSource as FrameworkElement;

and it should work
