Dynamically add and remove controls, using uwp windows 10 visual studio 2015 - dynamic

Question

Edit:23-10;15:37h
Lets make one very big story very small. I've found out a lot!
first impressing of possibible layout
I want a program, were I can place/replace/rotate/adjust/remove fences in a field.
At this point I drag the fences from the listview into the canvas. But now I have a problem. I can't give those a name. I can't find a way to interact.
And seeing that I have come this far. Perhaps it's best to consider a save/load option. I expect some sort of csv of xml file could be used.
xaml.cs
byte Selectie = 0;
private void parcours_Drop(object sender, DragEventArgs e)
{
var pointer = e.GetPosition(parcours);
//following lines are used to create an object.
if (Selectie !=0)
{
Image enkel = new Image();
enkel.Width = 70;
enkel.Height = 70;
if (Selectie == 1)
{
enkel.Source = new Windows.UI.Xaml.Media.Imaging.BitmapImage(new Uri("ms-appx:///Assets/hindernissen_01.png"));
}
if (Selectie == 2)
{
enkel.Source = new Windows.UI.Xaml.Media.Imaging.BitmapImage(new Uri("ms-appx:///Assets/hindernissen_02.png"));
}
if (Selectie == 3)
{
enkel.Source = new Windows.UI.Xaml.Media.Imaging.BitmapImage(new Uri("ms-appx:///Assets/hindernissen_03.png"));
}
enkel.CanDrag = true;
parcours.Children.Add(enkel);
Canvas.SetTop(enkel, pointer.Y - 35);
Canvas.SetLeft(enkel, pointer.X - 35);
}
if (Selectie == 0)
{
Canvas.SetTop(enkel, pointer.Y - 35);
Canvas.SetLeft(enkel, pointer.X - 35);
}
Selectie = 0;
}
private void parcours_DragOver(object sender, DragEventArgs e)
{
e.AcceptedOperation = Windows.ApplicationModel.DataTransfer.DataPackageOperation.Move;//you must accept accept a drop. prevents it from dropping anywere.
}
private void tripple_DragStarting(UIElement sender, DragStartingEventArgs args)
{
Selectie = 3;
}
private void dubbel_DragStarting(UIElement sender, DragStartingEventArgs args)
{
Selectie = 2;
}
private void enkel_DragStarting(UIElement sender, DragStartingEventArgs args)
{
Selectie = 1;
}
