How to change the position of Expand / Collapse button in Tree View in WPF?

I have a tree view in WPF in C# with parent and child nodes. I want to bring the Expand/Collapse button to the right side. I tried the flow direction property but it is not working as expected.
How to change the position of the Expand/Collapse button in tree view?

Your best approch if you override the Treeview Control Template. Here is an example:
<Window.Resources>
<Color x:Key="SelectedBackgroundColor">#FFC5CBF9</Color>
<Color x:Key="SelectedUnfocusedColor">#FFDDDDDD</Color>
<Color x:Key="GlyphColor">#FF444444</Color>
<Color x:Key="GlyphMouseOver">sc#1, 0.004391443, 0.002428215, 0.242281124</Color>

ListView background colour not working

I have a simple listView put inside other elements.
Since I want to simulate an explorer style I have done that:
<ListView x:Name="lvAllowedPPtab2" Grid.Row="1" FontSize="12" Background="{x:Null}" BorderBrush="Gainsboro" BorderThickness="5" Margin="10" VerticalAlignment="Stretch" >
<ListView.ItemsPanel >
<ItemsPanelTemplate >
<WrapPanel Orientation="Horizontal" Width="250" Background="{x:Null}" VerticalAlignment="Top"></WrapPanel>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
</ListView>
the problem is that by doing that the background gets coloured while i want it to be transparent = null.
By looking at that
Datagrid foreground colour not working
as a workaround i've searched for something similar but didn't find any similar event.
Don't know if posting my complete xaml helps

the same problems happens everywhere in my xaml. Even just adding a empty listview with a transparent or null background makes it darkblue. I think I can't override the presets of my styled winwdow.

Changing the label foreground on mouseover, but the label is inside of button content

I am new at WPF and XAML, but still as I was reading about this is tricky thing. The thing what I want to change on mouseover is the Label foreground color, but the label is inside of the button content. Everything should be done by styles, without C#.
<Button Name="Home_Button" Height="50" VerticalAlignment="Top" Click="Home_Click" Background="Gray" Foreground="{x:Null}" BorderBrush="{x:Null}" BorderThickness="0">
<DockPanel>
<Image Source="Images/icons/home.png" HorizontalAlignment="Left" Margin="-90,0,0,0" />
<Label VerticalAlignment="Center" HorizontalAlignment="Right" Margin="0,0,-90,0" Foreground="LightGray" FontSize="12">Home</Label>
</DockPanel>
</Button>
My style settings looks like this:
<Style TargetType="{x:Type Button}" x:Key="MetroButton">

Now I wanna change the Foreground.Color on MouseOver on the Label which is inside of the Button. Right now the style settings only change the Background of the Button on MouseOver.

Put a sub style for Label inside the Style.Resources of your button style, this is a cut down example but should explain what I'm trying to say.

</Style>
</Window.Resources>
<Grid>
<Button Margin="172,122,131,79" Foreground="Green">
test
</Button>
</Grid>
</Window>
The Label style won't apply to anything outside of the Button, if you mouse over any part of the button area it'll turn the top half blue but will only turn the text green if the mouse is over the bottom half (which is covered by the label)

try this.
<Button Height="36" Margin="286,274,0,0" Width="74" MouseEnter="Button_MouseEnter_1">
<Label x:Name="mylbl" Content="Test" MouseEnter="mylbl_MouseEnter"/>
</Button>
code behind:
private void mylbl_MouseEnter(object sender, MouseEventArgs e)
{
mylbl.Background = new SolidColorBrush(Colors.Red);

I want to give it a minimum and maximum values to it considering minimum values to negative rather then it being zero.
**
How can i get a balance slider where one can slide to left or right position and center will be default providing them the horizontal fill on both the sides?
**

a control template don't seems to be the solution.
try just setting Maximum="1" Minimum="-1" Value="0" when using a slider for this case
