Tabs not showing up

[E]

Hi,
I derive my control from the tab control and when i try to add tabs to it, they do not show up...

 

this.Tabs.Clear ( );

 

 

foreach ( nsMy.TabEnum eTab

 

 

in System.Enum.GetValues ( typeof ( nsMy.TabEnum ) ) )

 

{

 

string sTab = this.GetTabResourceString ( eTab );

 

Telerik.WebControls.

Tab oTab

 

=

new Telerik.WebControls.Tab ( sTab );

 

 

this.Tabs.Add ( oTab );

 

oTab.Visible =

true;

 

oTab.Width =

this.Width;

 

oTab.Height =

this.Height;

 

}

The page renders with no tabs as follows...

 

 

<div id="SiteNavigationTabs" class="tabstrip RadTabStrip_Default " style="height: 52px;

 

width: 996px;">

 

 

 

 

 

<!-- 3.6.6 -->
