Hello John,

I will be happy to assist you with your question.

May I assume that you are using the UltraTabbedMdiManager to enable the tabbing of a form? If so, please use the available CloseButtonLocation property to change the location of the close button to Tab.

Example:
this.ultraTabbedMdiManager1.TabGroupSettings.CloseButtonLocation = Infragistics.Win.UltraWinTabs.TabCloseButtonLocation.Tab;

To learn more about this property, please visit our online help documents found using the link below:

Please let me know if you have any questions regarding this matter.
