Hi all I have a tab container declared as the following

<

cc1:TabContainer ID="TabContainer1" runat="server"> </cc1:TabContainer>

When I try to add tanbs to this container from the code behind in the page load I use the following code

protected void Page_Load(object sender, EventArgs e)
        {
            TabContainer1.Tabs.RemoveAt(0);
            AjaxControlToolkit.TabPanel panel1 = new AjaxControlToolkit.TabPanel();
            panel1.HeaderText = "panel1";
            panel1.Visible = true;
            panel1.ID = "panel1";


            AjaxControlToolkit.TabPanel panel2 = new AjaxControlToolkit.TabPanel();
            panel2.HeaderText = "panel2";
            panel2.Visible = true;
            panel2.ID = "panel2";

            TabContainer1.Controls.Add(panel1);
            TabContainer1.Controls.Add(panel2);
            
        }

when I run the page nothing appears

but if I declared a tabpanel as this

<cc1:TabContainer ID="TabContainer1" runat="server">
     <cc1:TabPanel ID="ss" runat="server">
     <ContentTemplate>
     123
     </ContentTemplate>
     </cc1:TabPanel>
        </cc1:TabContainer>

The same code works fine

so I guess in order to add tabs programmatically you should have at least one tab declared

is this assumption right ?

thanks

Ok I found it

In order to make the tabs appear you should write

TabContainer1.ActiveTabIndex = 0;

and there is no need to declare a panel at the begining

thanks
