Extended WPF Toolkit not showing String Collection in collection editor

Question

I am using the Extended WPF Toolkit for their property editor. http://wpftoolkit.codeplex.com/wikipage?title=PropertyGrid

I have a few StringCollection objects defined in my settings file that are being shown as System.Collections.Specialized.StringCollection rather than in a CollectionEditor.

Here is how I defined the property editor:

<xctk:PropertyGrid x:Name="SettingsGrid" SelectedObject="{Binding Source={x:Static properties:Settings.Default}}" IsCategorized="False">
</xctk:PropertyGrid>

is there additional setup required?

Answer 1

here is a sample for specifying custom editor for System.Collections.Specialized.StringCollection in PropertyGrid

<xctk:PropertyGrid x:Name="SettingsGrid"
                   SelectedObject="{Binding Source={x:Static properties:Settings.Default}}"
                   IsCategorized="False"
                   xmlns:sp="clr-namespace:System.Collections.Specialized;assembly=System">
    <xctk:PropertyGrid.EditorDefinitions>
        <xctk:EditorTemplateDefinition TargetProperties="{x:Type sp:StringCollection}">
            <xctk:EditorTemplateDefinition.EditingTemplate>
                <DataTemplate>
                    <Expander Header="(StringCollection)">
                        <ListBox ItemsSource="{Binding Value}"
                                 HorizontalContentAlignment="Stretch">
                            <ListBox.ItemTemplate>
                                <DataTemplate>
                                    <TextBox Text="{Binding Path=.}" />
                                </DataTemplate>
                            </ListBox.ItemTemplate>
                        </ListBox>
                    </Expander>
                </DataTemplate>
            </xctk:EditorTemplateDefinition.EditingTemplate>
        </xctk:EditorTemplateDefinition>
    </xctk:PropertyGrid.EditorDefinitions>
</xctk:PropertyGrid>

before specifying the editor

after specifying the editor

this sample may not be exactly demonstrating how you want to edit the collection, you may adjust the template as needed
