By default the expander has a left aligned toggle button but in my WPF app i want toggle button on the right side of the header without the help of Expression Blend. just plain XAML and/or C#. My expander contains a vertically oriented stackpanel which has labels as its child.
I went for its part but here it says "The Expander control does not have any named parts".
I found an example here. But it overrides the default Expander Style.
I think the attached image should convey what i want. How to do. Any link would be helpful.
There is a trick that can help
<Expander Header="My Expander"
FlowDirection="RightToLeft">
<Expander.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding RelativeSource={RelativeSource AncestorType=Expander}, Path=Header}"
Width="{Binding RelativeSource={RelativeSource AncestorType=Expander}, Path=ActualWidth}"
Margin="-30,0,0,0"
FlowDirection="LeftToRight">
</TextBlock>
</DataTemplate>
</Expander.HeaderTemplate>
</Expander>
