A property of a complex type cannot be edited if the AllowInstanceInitializer property of the corresponding PropertyDefinition is set to False

created 9 years ago

[DevExpress Support Team: CLONED FROM T321536: PropertyGrid with ComboBoxSettings]

XAML
<dxprg:PropertyDefinition Path="*.ContextLayer">  
   <dxprg:PropertyDefinition.EditSettings>  
       <dxe:ComboBoxEditSettings ItemsSource="{Binding AllLayers}" DisplayMember="Name" IsTextEditable="False" />  
   </dxprg:PropertyDefinition.EditSettings>  
</dxprg:PropertyDefinition>

But now I have a "Layer" entry in the RowMenu. I thought I can disable this menuitem by setting AllowInstanceInitializer to false, but then I can't select any item from the combobox.

        XAML
        <dxprg:PropertyDefinition Path="ContextLayer" AllowInstanceInitializer="False" IsReadOnly="False" >  
    <dxprg:PropertyDefinition.EditSettings>  
        <dxe:ComboBoxEditSettings ItemsSource="{Binding AllLayers}" DisplayMember="Name" IsTextEditable="False"  />  
    </dxprg:PropertyDefinition.EditSettings>  
</dxprg:PropertyDefinition>
