                    </DataTemplate>
                </CollectionView.ItemTemplate>
            </CollectionView>


           Viewmodle =>

public DelegateCommand InfoCommand { get; set; }
InfoCommand = new DelegateCommand(ShowInfo);

private void ShowInfo(Picker picker)
{

    }

Whenever I click on the item of the collectionview nothing happening. As per my code it should call ShowInfo method.

Please help
