How do I filter and pagenate a WPF datagrid at the same time?

I am able to either paginate or filter the datagris seperately, but it seems like I cannot do both at the same time?

ObservableCollection<LotTracing> items = new ObservableCollection<LotTracing>();

       ICollectionView SourceCollection;
       public LotSearchUI()
       {
           InitializeComponent();
           items = sourceCollection;
           SourceCollection = CollectionViewSource.GetDefaultView(items);
           this.DataContext = this.SourceCollection;
           dataGrid1.ItemsSource = this.SourceCollection;

           foreach (var prop in typeof(LotTracing).GetProperties())
               comboBoxCategory.Items.Add(prop.Name.ToString());
       }

and then I have a filter on searchbox textchanged ..

private void SearchTextBox_TextChanged(object sender, TextChangedEventArgs e)
{
    this.SourceCollection.Filter = item =>
    {
        LotTracing vitem = item as LotTracing;
        if (vitem == null) return false;

        PropertyInfo info = item.GetType().GetProperty(comboBoxCategory.Text);
        if (info == null) return false;

        return info.GetValue(vitem, null).ToString().Contains(SearchTextBox.Text);

    };
}

What I have tried:

I have tried adding in the PagingCollectionView : CollectionView Samplle that is floating around but it doesn't respond to the filter. I see this being asked alot, but the answers all reference a site that is no longer active.
