UIType UIType { get; set; }

Property Value

Type Default Description
UIType MultipleWindowSDI

A UIType enumeration value specifying the type of the UI used in the WinForms application.


We do not recommend setting this property to StandardMDI when the Ribbon interface is used. This configuration has not been thoroughly tested, as we have found it much less usable than others, and can potentially lead to errors. In conjunction with the Ribbon, the TabbedMDI mode provides better usability.

The following images demonstrate how the WinForms application UI is modified depending on this property’s value.

  • MultipleWindowSDI


  • SingleWindowSDI


  • StandardMDI


  • TabbedMDI
