If you are talking about disabling the tabs (rather than the controls in the tabpage), then the .net tab control doesn''t let you do this. The Syncfusion tab control (in Essential Tools) provides you this ability among other improvements.
To disable the controls in a tab page, simply the the tabPage.Enabled property to false.
