The skin name of the pager combobox always matches the skin name of the RadGrid control. So if you are using a custom skin for RadGrid, you should use one for the RadComboBox as well.
However, to achieve your goal the custom skin name should matches with the embedded skin name(Default
in your case). Then you can set EnableEmbeddedSkins="true" for the pager combobox in RadGrid.ItemCreated and the control will use its embedded skin.
Give this suggestion a try and let me know how it goes.
All the best,
the Telerik team
