Answer 1

Define this control in your XAML

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=Name}" />
            <GridViewColumn Header="Description" DisplayMemberBinding="{Binding Path=Description}" />
        </GridView>
    </ListView.View>
</ListView>

and then in the code-behind you can add new items to the List view by typing:

listView.Items.Add(new Item());

And the class Item contains the properties Name and Description.

If you want to change the columns shown, then change the XAML.

This is not a good approach, as here you aren't using MVVM, what you should do is bind the ListView ItemsSource property to a collection in your ViewModel, and then work over that collection.
