I am using Template10. I am utilizing a ListView. The ViewModel needs to know the SelectedItems. The SelectedItems should be passed as a parameter with a converter. EventTriggerBehavior EventName="SelectionChanged" is tested working. The converter is tested working. DelegateCommand> SelectionChangedCommand is NOT working. DelegateCommand of anything is NOT working (no string, no int - no nothing). DelegateCommand SelectionChangedCommand is tested working. Only DelegateCommands without parameter are working when ListView -> EventTriggerBehavior -> InvokeCommandAction Any ideas?
DelegateCommand<object> is not beeing invoked

I think I found the solution.
I changed the converter, so that it is returning a
List<string>instead ofIList<object>. It Looks like that theDelegateCommand<T>in the ViewModel did not match the<T>coming from the the converter/ListView althoughListView.SelectedItemsisIList<object>. Furthermore I changed the concept, now the Delete Buttons gets the list of selected items which saves some Code, Events and doubled lists.
