[Solved] Change Expander Button Style

[Michael]

Hi, I'm trying to change the default expander button style in the radcolorpicker. Here is a snippet:

<Style x:Key="ExpanderButtonStyle" TargetType="Button">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <StackPanel Orientation="Horizontal">
                      <TextBlock Text="Background Color: "/>
                      <Rectangle Width="16" Height="16" Fill="{TemplateBinding Background}"/>
                    </StackPanel>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

And I am getting the following error in Blend: (in attached image)

I'm trying to make it look like attached image:

I hope you can help me. Thanks

Hi Michael,

We logged this issue in our PITS (ColorPicker: The default "ExpanderButtonStyle" cannot be edited in Expression Blend) where you will be soon able to vote for. We also updated your telerik points.
I've attached the default style of this expander button and you will be able to modify it.
Feel free to ask if you need further assistance.
