The tab items of the DocumentWindows
have a predefined shape applied (TabVsShape). You can change it by using the RadDockEvents.TabStripItemCreating
event. Additional information is available in the last section of the following help article: http://docs.telerik.com/devtools/winforms/dock/object-model/customizing-tabstrip-items
If you have any questions related to using the Telerik UI for WinForms suite in the OpenEdge environment, you will have to submit your further requests in Salesforce via SupportLink:
Thank you for your understanding.
I hope this information helps.
