Hi,

I can't find any way to data bind in a panel bar. We are creating a WCF service that contains two level of data. A top level "GROUP" and "FILTERS" in second level. Binding to itemsource generates the GROUP level panels but not creating the FILTER levels. Is there any solution or code?

Let me know ASAP.

Thanks

Hi Chris,

You should use a HierarchicalDataTemplate. Take a look at the following two links:

http://demos.telerik.com/silverlight/#PanelBar/DataBinding
http://www.telerik.com/help/silverlight/common-data-binding-hierarchical-data.html

Let me know if you still have difficulties after looking at the example and help article.

I bind a ObservableCollection to a panelbar using HierarchicalDataTemplate,but when I add a object to the ObservableCollection,panelbar doesn't refresh. 

I has to set panelbar's itemsource to null and then set the itemsource to the ObservableCollection again.
 
Can panelbar implement load on demand?

Hello yjh,

if you are binding to an ObservableCollection the panel bar should update itself automaticaly. Can you open a support ticket and attach a project that we can investigate.

Thanks!
