I have been working around with the Silverlight Pivot Viewer for long time now and I have noticed that whenever I use a JIT collection I dont see Description in the facet panel but when I use a static collection, Description is available. First I thought maybe description facet is not allowed in JIT collections but then I remembered that the Collection class constructor does ask for Description in its parameter, this made my curious and I started dive into the code of PivotServerTools Project and I found that there’s no place in the code where this Description is used apart from when creating the default item images. After a lot of searching I was able to find a solution using which Description can be made visible. To do so, follow the below steps:

1. Go to the PivotServerTools project.
2. Open the Internal folder.
3. There you’ll see a “CxmlSerializer” class, this class is used when the method Collection.ToCXML() is invoked, which is done by the Pivot Viewer. Open this class and navigate to the method “MakeItemContent”. In this method add the following line:

if (!string.IsNullOrEmpty(item.Description)){
	yield return new XStreamingElement(Xmlns + "Description", item.Description);

This way Description will start showing up in the Facet panel of every collection provided you specified a value for it in the Item’s collection class constructor.
