How to fill listview in WPF C#

I`m trying to fill list view on window loaded event but Nothing comes out.

This is my XAML

<ListView Height="142" Name="listView1" Width="371">
            <ListView.View>
                <GridView>
                    <GridViewColumn Width="60" Header="ID"/>
                    <GridViewColumn Width="300" Header="User Name" />
                </GridView>
            </ListView.View>
        </ListView>
    </GroupBox>

this my c# code :

  private void Window_Loaded(object sender, RoutedEventArgs e)
    {

        ArrayList _ID = new ArrayList();
        ArrayList _UserList = new ArrayList();

        using (DataClasses1DataContext dc = new DataClasses1DataContext())
        {
            var Users = (from u in dc.users select u.username).ToList();

            for (int i = 0; i < Users.Count(); i++)
            {
                _UserList.Add(Users[i]).ToString();
            }


            using (DataClasses1DataContext dcc = new DataClasses1DataContext())
            {
                var ID = (from u in dcc.users select u.id).ToList();

                for (int i = 0; i < ID.Count(); i++)
                {
                    _ID.Add(ID[i]).ToString();
                }

            }
        }

Well ListView1 ist not bound to any datasource.

also the generated arrays are never assigned to the list view....

Have a look at the ItemSource Property

First make on object, i see you have 2 different lists. Just use one object, keeping both data. Next, like H.B. said, you need to specify what each columns shows. The simple way is to use DisplayMemberPath, the more complex but also more flexible solution is to use a specialized CellTemplate.

if your data object looks like this

public class MyObject
{
   public int Id{get;set;}
   public string Name {get;set;}
}

your ListView holding a list of these items in xaml would look like.

<ListView.View>
    <GridView>
        <GridViewColumn Width="60" Header="ID" DisplayMemberBinding="{Binding Id}"/>
        <GridViewColumn Width="300" Header="User Name" DisplayMemberBinding="{Binding Name}" />
    </GridView>
</ListView.View>

Hope that helps.

GridViewColumns work via the DisplayMemberBinding or the CellTemlate. You specify neither.

Further i do not see you reference the ListView in your code at all, at the very least you would need to add items via ListView.Items.Add or by setting the ListView.ItemsSource.
