Hi,

I'm just checking have you been able to resolve your issue? If you still have any concerns or questions I will be glad to help.

Thank you for choosing Infragistics.

Hello Dimitry,

TabPaneGroup has an items collection. You do not have to explicitly declare tags for the TabGroupPane object's Items collection. However every pane placed in the TabPaneGroup is placed in that Items collection and that is the reason to be considered of type PaneTabItem. So  as Andrew Smith had suggested you can search  the templates for the igDock:PaneTabItem.UnpinnedTabItemTemplateKey, igDock:PaneTabItem.DocumentTabItemTemplateKey, igDock:PaneTabItem.DockableTabItemTemplateKey if you want different appearance of the tabs. You can find default templates on your computer in the file \Infragistics\NetAdvantage2010.3\WPF\DefaultStyles\DockManager\DockManagerGeneric.xaml copy them in your code and change the properties you want  to customize.

If you need any further assistance on the matter please do not hesitate to ask.

So if i started a brand new project and added some Tabs in the DockManager document and wanted to change these what are the steps i should take?

In your samples "DocumentContentHost" has a "SplitPane" that hosts a "TabGroupPane" and contains the view i created itself within "ContentPane". When i search though for "PaneTabItem.DocumentTabItemTemplateKey" i find that its part of the template for something called a "PaneTabItem" so im a bit confused.
