Can you point me to a PopupButton sample that has the button looking like a combo box with an Image and Text?

Hi John,

Are you referring to the PopupButton in the Shared Library?  If so, check out the "PopupButton Features" sample.  That shows how you can set a "Merged" display mode to make it look like a read-only ComboBox.  You can set the Content property to anything, including a StackPanel of Image and TextBlock if you want to show both image/text there.

Thanks.  A corporate style was preventing my stackpanel content from working.  

Can you make the default drop arrow match WPF combo boxes?

<Path x:Name="arrow" HorizontalAlignment="Center" VerticalAlignment="Center" Data="M 0,0 L 2.5,3 L 5,0 Z"/>

Actually,  our style makes the popup button behave a lot more like a combo box which is what I want.   For example, the arrow is the correct size and the hover highlighting only affects the arrow rectangle, not the whole button.   How would I add an image to the content when using this style or another one like it.   Not sure how to bind the image...

  <Style x:Key="ComboBoxPopup" TargetType="{x:Type ActiproShared:PopupButton}" BasedOn="{StaticResource {x:Type ActiproShared:PopupButton}}">
    <Setter Property="Template">
      <Setter.Value>
        <ControlTemplate  TargetType="{x:Type ActiproShared:PopupButton}">
          <Border Background="{TemplateBinding Background}" 
                  BorderBrush="{TemplateBinding BorderBrush}" 
                  BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0">
            <Grid VerticalAlignment="Center">
              <Grid.ColumnDefinitions>
                <ColumnDefinition/>
                <ColumnDefinition Width="Auto"/>
              </Grid.ColumnDefinitions>
              <TextBlock x:Name="text" VerticalAlignment="Center"
                        Text="{TemplateBinding Content}" 
                        Foreground="{DynamicResource Gray145}" Margin="2,0,6,0"/>
              <Border x:Name="border" Grid.Column="1"

Hi John,

Actually our ComboBox style uses "M 0,0 L 2.5,3 L 5,0 Z".  We will update it to match that since it wasn't the same.

As for the image, you can use a ContentPresenter instead of TextBlock and have the content be a StackPanel of Image/TextBlock.
