Question

Below is the XAML i currently have. I want to emulate a tree by having a toggle button and a listview will bind it’s visibility to the toggle buttons chcked state. Problem is, I need to bind to a child of a sibling. Is this even possible?

this code doesn’t work becuase the toggle isn’t an ancestor.

            <StackPanel Orientation="Vertical">
                <StackPanel Orientation="Horizontal">
                        <ToggleButton Name="tglBtn">+</ToggleButton>
                            <TextBlock>test</TextBlock>
                </StackPanel>
                    <ListView Visibility="{Binding RelativeSource={RelativeSource AncestorType={x:Type ToggleButton}}, Path=IsChecked, Converter={StaticResource boolToVis}}">
                    <ListView.View>
                        <GridView>
                            <GridViewColumn Header="Thread"  DisplayMemberBinding="{Binding thread_name}" />
                            <GridViewColumn Width="Auto" Header="Created"  DisplayMemberBinding="{Binding thread_created}" />
                            <GridViewColumn Width="Auto" Header="Modified" DisplayMemberBinding="{Binding last_modified}" />
                        </GridView>
                    </ListView.View>
                </ListView>
            </StackPanel>

        </DataTemplate>
        </ListBox.ItemTemplate>


    </ListBox>

You can use ElementName Binding to access the ToggleButton
