Used to work in the previous version
Steps to Reproduce:
Here is my code:
procedure CopyObject(Source, Dest: TObject; isWA: Boolean = True);
begin
  if Assigned(Dest) then
  begin
   TdxNavBar(Dest).View := dxNavBarSkinExplorerBarView;
   if isWA then
    TdxNavBarSkinNavPanePainter(TdxNavBar(Dest).ViewStyle).SkinName := 'Office2007Blue'
   else
    TdxNavBarSkinNavPanePainter(TdxNavBar(Dest).ViewStyle).SkinName := 'Silver';
   TdxNavBarSkinNavPanePainter(TdxNavBar(Dest).ViewStyle).SkinNameAssigned := True;
  end;

    Hi David,
    The "How to Apply Skins in the Application" help topic shows a code example for a TdxNavBar control, if the NavBarSkinNavigatorPaneView is applied to its View property (dxNavBar1.View := dxNavBarSkinNavigatorPaneView). If you're applying the NavBarSkinExplorerBarView, you have to use the TdxNavBarSkinExplorerBarPainter instead:

    Delphi
    if isWA then  
 TdxNavBarSkinExplorerBarPainter(TdxNavBar(Dest).ViewStyle).SkinName := 'Office2007Blue'  
else  
 TdxNavBarSkinExplorerBarPainter(TdxNavBar(Dest).ViewStyle).SkinName := 'Silver';  

TdxNavBarSkinExplorerBarPainter(TdxNavBar(Dest).ViewStyle).SkinNameAssigned := True;

    Thanks,
    Alex

      Thank you very much for the quick and accurate answer. It works.
      However, you need to make some changes to the help file concerning the example brought on TdxCustomNavbar.ViewStyle

        Hi David,
        Thank you for informing us that the problem is resolved. Please feel free to contact us in case of any difficulty. We are happy to help you at any time.
        As for changes to the help topic, the code example in this topic is for the SkinNavigationPaneView only. Do you suggest adding a code example for the SkinExplorerBarView?
        Thanks,
        Alex
