            </TreeView>
        </GroupBox>
    </StackPanel>
</Grid>

Is there any way to do this ?

Yes. In your constructor set a property of type Visibility like this:

public class MyUserControl : UserControl
{
  public TreeViewVisibility { get; private set; }

  public MyUserControl(bool showTreeView)
  {
    TreeViewVisibility = showTreeView ? Visibility.Visible : Visibility.Collapsed;
    ...
  }
}

And bind to it in your XAML:

...
<TreeView Visibility="{Binding TreeViewVisibility,
           RelativeSource={RelativeSource FindAncestor,local:MyUserControl,1}}" />
