for more information check out documentation in msdn http://msdn.microsoft.com/en-us/library/system.windows.controls.listbox.selectall%28v=vs.110%29.aspx

im not sure if right way, works

 list<object> arr = new list<object>((((system.collections.generic.dictionary<string, string>)(s))).values);      (int k = 0; k < data.length; k++)                 {                     object selectitem = arr[k];                     items.add(selectitem);                 }    yourlistbox.selecteditems = items; 

this how made work in case way create list object containing elements data source , assigning to selected items.
