AllowExpand

Hi All,

I have declared a custom editor as follows:

<ms:PropertyGrid Name="propGrid">
    <ms:PropertyGrid.Resources>
        <DataTemplate x:Key="LookupEditorTemplate">
            <ComboBox ItemsSource="{Binding EditContext.Items}"
                               DisplayMemberPath="{Binding EditContext.DisplayMemberPath}"
                               SelectedValuePath="{Binding EditContext.SelectedValuePath}"
                               SelectedValue="{Binding Value.Value, Converter={StaticResource NullableInt32Converter}}">
            </ComboBox>
        </DataTemplate>
    </ms:PropertyGrid.Resources>
    <ms:PropertyGrid.Editors>
        <Editors:LookupEditor EditorTemplate="{StaticResource LookupEditorTemplate}" AllowExpand="False" />
    </ms:PropertyGrid.Editors>
</ms:PropertyGrid>

This allows me to select an instance of a list and associate it with the property of my object. All works well except that the end-user is able to expand the property, because the instance is a class itself with (sub)properties.

How can I prevent the expand. I have tried AllowExpand is false (as can be seen in the XAML snippet).

Thanks in advance for any help,

Hi Jan,

Setting AllowExpand to false certainly should work (in fact this is the default so you shouldn't even need to do this explicitly).  Could you send us a sample project which demonstrates the problem please, so we can investigate?  You can attach a zip file via the Options tab.  Thanks!
