Bill,

It appears that this is a development issue which I will submit to our development team.  You will receive more information on this through the support case.

Hi Michael,

  That fix did not work.  I attached a sample application which shows the problem.  Run the program and you will see a dock with 3 tabs on the bottom.  You can not drag the tabs out into a floating dock pane by their tab areas.  This is just one issue, there is other behavior that no longer works as well.  I believe this is because the dock manager hooks the parent form of the HostControl which doesn't exist in my case.  The fix you sent seems to deal only with floating panes.  The dock works fine inside the designer in VS2010 which does not have a parent Form (I'm guessing) so maybe there is hope.

Thanks for your help.

Bill

Bill,

Actually support has been added to the dock manager for a top-level non-Form window.  Here is a suggestion from one of our developers:   You have to use a derived dockmanager and override InitializeFloatingWindowContainer.  Here's an example:

public class MyDockManager : UltraDockManager
{
private const int GWL_HWNDPARENT = -8;

[DllImport( "user32.dll", CharSet = CharSet.Auto, ExactSpelling = true )]
private static extern IntPtr GetParent( IntPtr hWnd );

[DllImport( "user32.dll", EntryPoint = "SetWindowLong", CharSet = CharSet.Auto )]
private static extern IntPtr SetWindowLongPtr32( IntPtr hWnd, int nIndex, IntPtr dwNewLong );

[DllImport( "user32.dll", EntryPoint = "SetWindowLongPtr", CharSet = CharSet.Auto )]
private static extern IntPtr SetWindowLongPtr64( IntPtr hWnd, int nIndex, IntPtr dwNewLong );

public MyDockManager( IContainer container )
  : base( container )
{
}

public static IntPtr SetWindowLong( IntPtr hWnd, int nIndex, IntPtr dwNewLong )
{
  if ( IntPtr.Size == 4 )
   return SetWindowLongPtr32( hWnd, nIndex, dwNewLong );

  return SetWindowLongPtr64( hWnd, nIndex, dwNewLong );
}

protected override void InitializeFloatingWindowContainer( FloatingWindowContainer floatingWindowContainer )
{
  if ( floatingWindowContainer.Owner != null )
   return;

  if ( this.HostControl == null )
   return;

  IntPtr topLevelWindow = this.HostControl.Handle;
  IntPtr parentWindow = MyDockManager.GetParent( topLevelWindow );

  while ( parentWindow != IntPtr.Zero )
  {
   topLevelWindow = parentWindow;
   parentWindow = MyDockManager.GetParent( topLevelWindow );
  }

  MyDockManager.SetWindowLong(
   floatingWindowContainer.Handle,
   MyDockManager.GWL_HWNDPARENT,
   topLevelWindow );
}
}

I hope this helps.  Let us know if you have further questions.

Ok, I was not aware that the infragistics winforms controls are not supported inside a WPF window.  Can you point me to a document stating this? Thanks.

I thought it might be worth a try, but I don''t have any other suggestions since this is not a supported scenario.

Let us know if you have any further questions.
