How to skip serialization of individual child controls?

Question

Hello!

The problem i'm faced with is to omit serialisation of specifc child controls of my UIElement-based WPF control.

More precisely, I have MyWindowsFormsHost derived from WindowsFormsHost. An instance of this is populated with a child control (say, different types of data grids, charts, whatever), linked with a IBindingList-based collection

   public class MyWinFormsDataGridView : WindowsFormsHost, IMyUIElement
    {
        DataGridView _gridView;
        public MyWinFormsDataGridView()
        {
            this._gridView = new DataGridView();
            this._gridView.DataSource = ...;
            this.Child = this._gridView;
        }
    }

When I save a grid with and instance of this class in XAML (simply by XamlWrite.Save(grid) ), I get tones of data from data binding, and corresponding perfomance drop:

<MyGrid Name="grid1">      
   <MyWinFormsDataGridView ...>
      <swf:DataGridView ...>
         ...
         <swf:DataGridView.DataSource>
             <MyBindingList><tones of data i dont need to save...></MyBindingList>
         </swf:DataGridView.DataSource>
      </swf:DataGridView>
   </MyWinFormsDataGridView>
</MyGrid>

I would like to skip saving

<swf:DataGridView ...>
         ...
         <swf:DataGridView.DataSource>
             <MyBindingList><tones of data i dont need to save...></MyBindingList>
         </swf:DataGridView.DataSource>
      </swf:DataGridView>

and have in the output only the following:

<MyGrid Name="grid1">      
   <MyWinFormsDataGridView>...</MyWinFormsDataGridView>
</MyGrid>

Can anybody indicate a relatively simple solution for this?
