I have created a control derived from the xamComboEditor, however when i set the Theme Property it is not applied. I believe this is because in the background the Theme is applying a style, which has a TargetType of xamComboEditor. Is there any way i can use the infragistics supplied themes on a class that is derived from the infragistics control?

A simple example of what i am trying to achieve is shown below.

<Window x:Class="wpfInfragisticsLookupTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" xmlns:igEditors="http://infragistics.com/Editors" xmlns:my="clr-namespace:wpfInfragisticsLookupTest">
    <StackPanel>
        <igEditors:XamComboEditor Name="xamComboEditor1" Theme="Office2010Blue"/>
        <my:xamLookup x:Name="xamLookup1" Theme="Office2010Blue"/>
    </StackPanel>
</Window>

namespace wpfInfragisticsLookupTest
{
    public class xamLookup:Infragistics.Windows.Editors.XamComboEditor
    {
        public xamLookup()
            : base() {}
    }
}
