I found that you need to set the DrawMode property to TabDrawMode.OwnerDrawFixed<wbr /> and write some code into the DrawItem to be able to change the font or the apprearance of a TabPage caption.

<div class="content wysiwyg-content">
I am building an application using Windows Forms (VB.Net 2003).<br />
<br />
I need to disable some pages of a tab control depending on users privileges. It seems that the Enabled property disable the content of the tabpage and not the access to the tabpage.<br />
<br />
Then I found <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbtskdisablingtabpagesprogrammatically.asp" rel="ugc nofollow">http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbtskdisablingtabpagesprogrammatically.asp</a>&nbsp;which is using the SelectedIndexChange to detect when a tab is selected and switch to another. <br />
<br />
There are 2 things that I don't like about this:<br />
1. There is a visual flicking. How can we stop the flicking?<br />
2. There is no visual clues that the tab is not enabled. How can we gray the caption of the tab page?<br />
<br />
Or if you have better ideas please tell me!
