If the goal is to create an AutoCAD Table with the contents of the current selection, you do not need all this Palette WPF MVVM Bindings stuff.
But if you want to keep on the WPF MVVM Bindings route, you should bind your button to a property of the ViewModel which type implements ICommand instead of handling the Button_Click event (as shown in
this example) and you would not relay on the View (the ListView items) to fill the table but simply use the Selection property of the ViewModel which contains the data you need.
Note: as said in the
first message of this thread: "Please post questions in a regular thread".
