I have a user control which has few controls.

        <UserControl>
          <Grid>
    <Expander Header="{Binding Path=Headerval}">
        <StackPanel Margin="10,4,0,0">
            <DataGrid
          x:Name="dataGrid"
         AutoGenerateColumns="False"
         ItemsSource="{Binding Path=records}"/>
        </StackPanel>
    </Expander>
</Grid>
</UserControl>

I am using this set of user controls as my itemsource in my Listbox

    <ListBox x:Name="myListBox" ItemsSource="{Binding Path=_myControl}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <NewWPFApp:MyUserControl />
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>

    </ListBox>

and in my Mainwindow Code

   public ObservableCollection<GetControlsList> _myControl { get; set; }

   _myControl = new ObservableCollection<GetControlsList>();
        _myControl.Add(new GetControlsList(new MyUserControl()));

  public class GetControlsList
{
    public ObservableCollection<MyUserControl> _ListControls = new ObservableCollection<MyUserControl>();
    public GetControlsList(params MyUserControl[] controls)
    {
        foreach (var control in controls)
        {
            _ListControls.Add(control);
        }
    }
    public ObservableCollection<MyUserControl> ListCOntrols
    {
        get { return _ListControls; }
    }
}

However here Initializecomponent of MyUserControl is called twice

What can I do about it ??

Thanks
