Long ago, I looked at this MSDN walkthrough. It implements a color editor, and the tooltip uses the color’s name like ‘Red’ or ‘Blue’.

Today, I’m implementing a ListBox that is similar; it displays a box with the color and the name of the color next to it. Except in my application, all of the color names display as the hex values like #FFFF0000 and #FF0000FF. Why?

Here’s the ColorsList class used in both projects:

public ColorsList() {     Type type = typeof(Colors);     foreach (PropertyInfo propertyInfo in type.GetProperties(BindingFlags.Public | BindingFlags.Static))     {         if (propertyInfo.PropertyType == typeof(Color))         {             Add((Color)propertyInfo.GetValue(null, null));         }     } }

This XAML snippet makes the tooltip use the color name in the MSDN project (you can see the rest of the code in the walkthrough):

<ItemsControl.ItemTemplate>     <DataTemplate>         <Button Tag='{Binding}' Command='{x:Static PropertyEditing:PropertyValueEditorCommands.ShowInlineEditor}'>             <Button.Template>                 <ControlTemplate>                     <Border Width='30' Height='30' BorderBrush='Black' BorderThickness='1' CornerRadius='5'>                         <Rectangle Width='22' Height='22' ToolTip='{Binding}'>                             <Rectangle.Fill>                                 <SolidColorBrush Color='{Binding}'/>                             </Rectangle.Fill>                         </Rectangle>                     </Border>                 </ControlTemplate>             </Button.Template>         </Button>     </DataTemplate> </ItemsControl.ItemTemplate>

Here’s my XAML that produces the hex codes:

<ListBox x:Name='lstColors' Grid.Row='1' ItemsSource='{StaticResource colors}'>     <ListBox.ItemTemplate>         <DataTemplate>             <StackPanel Orientation='Horizontal'>                 <Rectangle Stroke='Black'                            StrokeThickness='3'                            Width='24'                            Height='24'                            RadiusX='5'                            RadiusY='5'>                     <Rectangle.Fill>                         <SolidColorBrush Color='{Binding}' />                     </Rectangle.Fill>                 </Rectangle>                 <TextBlock Text='{Binding}' />             </StackPanel>         </DataTemplate>     </ListBox.ItemTemplate> </ListBox>

It looks the same to me; what’s the difference?

  1. It turns out design-time is different from run-time. The MSDN example is used as an extended property editor. I took a friend’s advice and tried exposing it as a runtime control, and magically it’s getting hash names for colors instead of friendly names. Neat.
