Hide Show tabs of TabContainer control based on condition ASP.Net

Do as following

 int tabToBeShown = 8;
        for (int i = 0; i < TabContainer1.Tabs.Count; i++)
        {
            if ((tabToBeShown - 1) != i)
            {
                TabContainer1.Tabs[i].Visible = false;
            }
        }

after debugging found ou the following

//TabContainer1.Tabs[0].Visible = false;                         TabContainer1.Tabs[1].Visible = false;                         TabContainer1.Tabs[2].Visible = false;                         TabContainer1.Tabs[3].Visible = false;                         TabContainer1.Tabs[4].Visible = false;                         TabContainer1.Tabs[5].Visible = false;                         TabContainer1.Tabs[6].Visible = false;                         TabContainer1.Tabs[7].Visible = false;                                               TabContainer1.Tabs[8].Visible = true;                         TabContainer1.Tabs[9].Visible = false;                         TabContainer1.Tabs[10].Visible = false;

this works fine

i mean if TabContainer1.Tabs[0].Visible =true ; then the condition works fine for hide & show logic

but ifi uncomment from

TabContainer1.Tabs[0].Visible = false; then nothing is visible

does it mean tha the tab 0 shld always be visible???

Yes
