Display array data from web service in a List box with XML

Hello,

I am trying to display nested data returned from a web service in a list box. The data coming back is in an array and is thread colors from an embroidery design. i am simply trying to list those colors in a List Box using XML.

Here is the data returned from the webservice:

<DesignParameters xmlns="http://mywebservice.com/webservices">
  <DesignParameter xmlns="" ERRORSTATUS="SUCCESS" ERRORDESCRIPTION="Data Processed Successfully!">
 <PathAndFilename>\\9e1713389xaf1.ofm</PathAndFilename>
<PatternWidth>215.60</PatternWidth>
<PatternHeight>113.10</PatternHeight>
 <StitchCount>29736</StitchCount>
 <ColorCount>5</ColorCount>
<SequinCount>0</SequinCount>
<AppliqueCount>0</AppliqueCount>
<Rotation>0.00</Rotation>
 <LetteringObjectCount>2</LetteringObjectCount>
<ThreadColors>
<ThreadColor>
<![CDATA[ #FFFFFA ]]>
</ThreadColor>
<ThreadColor>
<![CDATA[ #68E6E8 ]]>
</ThreadColor>
</ThreadColors>
</DesignParameter>
</DesignParameters>

The specific array that I am trying to place in my ListBox is the ThreadColors, each value should appear as a hex number. But what is displayed instead is "DesignParametersDesignParamaterThreadColor". The binding i am using is ItemsSource="{Binding ThreadColors}"

The hex values will display correctly in a DataGrid when using the ItemsSource="{Binding ThreadColors}", but I need them to be in a ListBox for the UI I am putting together.

i cannot include a link to the webservice or any specifics to what this is being used for. I am simply looking for some guidance. Any thoughts would be helpful
