Direction for expander arrow is incorrect

[Xaria D]

I feel the arrow for expander and panel bars  points wrongly, it should behave opposite to how it is now.
How to modify  the arrow?

Hi Xaria D,

You can set the DecoratorTemplate property to any ControlTemplate for a ContentControl:

<Grid.Resources>
    <ControlTemplate TargetType="ContentControl" x:Key="decorator">
        <Rectangle Fill="Red" Width="10" Height="10" />
    </ControlTemplate>
</Grid.Resources>

<telerik:RadExpander DecoratorTemplate="{StaticResource decorator}" >
    <Button Content="Some Content" />
</telerik:RadExpander>

I am using  Q3 2009 and I get "The property DecoratorTemplate was not found in type RadExpander"

Hi Xaria D,

Indeed this property was added in a later release. If it is not an option for you to upgrade, I can suggest editing the RadExpander's ControlTemplate.

In Q3 2009's release the arrow can be changed from there (you can look for the ToggleButton in the RadExpander's template).

Kind regards,
