Find which button is clicked

Question

In my windows phone application, I have a LoadMore button in one page. The loadmore button is defined in style in <phone:PhoneApplicationPage.Resources> section. I have 2 listboxes in that page and uses the same style for both of the listboxes. When I click on the loadmore button, how can I identify the LoadMore button in which listbox raise the event?

<phone:PhoneApplicationPage.Resources>
        <Style x:Key="ListBoxStyle" TargetType="ListBox">
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
            <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled"/>
            <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Visible"/>
            <Setter Property="BorderThickness" Value="0"/>
            <Setter Property="BorderBrush" Value="Transparent"/>
            <Setter Property="Padding" Value="0"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListBox">
                        <ScrollViewer x:Name="ScrollViewer">
                            <StackPanel>
                                <ItemsPresenter/>
                                    <Button Content="Load More..." Name="btnLoadMore" Visibility="Visible" Background="White" Foreground="#FF176DDC" Click="btnLoadMore_Click"></Button>
                            </StackPanel>
                        </ScrollViewer>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </phone:PhoneApplicationPage.Resources>

How can I find the button in which listbox is clicked?

Answer 1

To have that kind of functionality in a style in my opinion is the wrong approach. Try putting the ListBox and the Button into a UserControl, that itself exposes an event for loading more data. Internally you then handle the Click-event of the button and raise the UserControl's LoadMore-event.
