  Hi, I seem to have bumped into a bug with the RibbonBar control.
  
  When setting SelectedTabIndex having 4 tabs, all of the visible, everything works normally:
  
  Ribbon.SelectedTabIndex = Ribbon.Tabs.IndexOf(Ribbon 
  .FindTabByValue("tabName"))
  
  However when I make some tabs invisible (index 0 and 2 in my case), it completely messes up the SelectedTabIndex property:
  
  It defaults to 1, and it seems to be impossible to change. Even having this value it is still inconsistent, showing either tab 1 or 3:
  
  When tab 1 is selected client side and a postback occurs, the selected tab will switch to 3 on the client side after postback and vice versa. 
  
  To make the tabs invisible I use: 
  Menu.Tabs(0).Visible = False
  Menu.Tabs(2).Visible  = False
  
  Am I making a mistake or is this really a bug? 
  
  Update:  It works when programatically removing the tabs before setting the index. This works for me as I won't need the invisible tabs on the client side or serverside anyway, but I imagine this might cause problems for other people.

  Hi Ioish,
  
  Unfortunately I wasn't able to reproduce this issue. Perhaps I am missing something. Could you please specify the exact sequence of actions that leads to the problem. A video capture of it would also be very helpful.

  I'd like to confirm this bug as stated by the original poster. When setting tab visibility, at least programmatically via C# code behind, the current RadRibbonBar selected tab index is lost (actually rewritten).
  
  Example:
  
  There are 7 visible tabs (indexes 0-6) and  fifth tab was selected as active (RadRibbonBar.SelectedTabIndex = 4). Make second tab invisible now (index 1) and RadRibbonBar.SelectedTabIndex now equals 5 which points to a different tab being selected than one desired.
  
  It seems RadRibbonBar.SelectedTabIndex property is maintained only for visible members of collection although oddly the tab count does not increase/decrease.
  
  I'm somewhat at odds with the original post as making the tabs invisible before setting the index screws things up anyway (using said C# code behind approach).
  -----------------------------------------------------------------------
  Code sample:
  
          private void DirectoryTabSetUp()
          {
              if (ClientsModules.HasFlag(ClientsModuleTypes.DirectoryAccess))
              {
                  if (CurrentUserSettings.ContainsKey(UserSettingTypes.DirectoryAccessOnly))
                  {
                      ribTabDrawings.Visible = true;//albeit this will be simplified version of Drawings
                      ribTabFiles.Visible = false;
                      ribTabAdmin.Visible = false;
                      rbTabReporting.Visible = false;
                      ribTabExplore.Visible = false;
                      RadRibbonBar.SelectedTabIndex = 4;
                      SimpleDrawingTabSetUp();
                  }
              }
              else
              {
                  ribTabDirectory.Visible = false;                
              }
  
          }
  
  ------------------------------------------------------------------------
  
  For the above sample, all that matters is that ribTabDrawings has a tab index of 0 in collection and ribTabDirectory has tab index of 4. When one sets RadRibbonBar.SelectedTabIndex = 4 in the code above, SelectedTabIndex is coalesced to 0 making ribTabDrawings tab active. If I now wanted to make ribTabDirectory selected I'd need to code RadRibbonBar.SelectedTabIndex = 1 (effectively saying, hey there are now only 2 visible tabs, make the second one active). But that's just visual order (from left to right to boot).
  
  
  Thanks,
  Ned
