Hi Eng,

Thank you for contacting us. Before we can answer your question could you please tell us if you're using the regular Windows Phone ListBox or Telerik's DataBoundListBox? Also, are you using the ExpaderControls inside the ItemTemplate of the list control?

Hi Eng,

As this help article describes, using RadExpanderControl within a ListBox should be done by introducing an IsExpanded property on your view-models and twoway-binding it to the IsExpanded property of the expander within the item template. Provided that you have this setup, you can simply iterate over all items within your source and collapse the ones different from the currently expanded one.
