Hello Aparnache,

I have been looking into this for you and since there is no built-in functionality for that one option would be to add an editor to the TabItemEx’s original control template. The templates can be found in the DefaultStyles folder default path: C:\Program Files (x86)\Infragistics\NetAdvantage 2011.2\WPF\DefaultStyles\Windows  e.g.: PrimitivesGeneric.xaml . On option for adding to the ControlTemplate would be to set the ContentTemplate of the ContentPresenter that actually displays the data in the tab header.

Another thing you can use would be, since the Header property is of type object an uses a ContentPresnter, to actually set it to an instance of the editor you’d like to use.

I have created a sample project (TabControl_editable_header.zip) for you describing both option I came up with.

Please let me know if I can be of any further assistance on the matter.
