Problem with TabPanel Control ActiveTab

[matmani]

Hello everybody,

The ActiveTab propriety does not work for me and has always the value -1.

This is my code:

Page.aspx

<ext:TabPanel ID="tabs"  runat="server" AutoPostBack="true"    Title="TabPanel">
                         
</ext:TabPanel>

Page.aspx..cs

protected void Page_Load(object sender, EventArgs e){


tabs.TabWidth = Unit.Pixel(135);
tabs.EnableTabScroll = true;
tabs.AutoPostBack = true;
tabs.TabChanged += new EventHandler(tabs_TabChanged);
 
Tab tab1 = new Tab();
tabMytheme.AutoWidth = true;
tabMytheme.ID = "tab1";

Tab tab2 = new Tab();
tabMytheme.AutoWidth = true;
tabMytheme.ID = "tab2"; tabs.Tabs.Add(tab1);
tabs.Tabs.Add(tab2);
...
}
.....
protected void tabs_TabChanged(object sender, EventArgs e)
{ 
TabPanel tabpanel = (TabPanel)sender;
Tab tab = tabpanel.Tabs[tabpanel.ActiveTab];   // The tabpanel.ActiveTab has always the value -1
string idProgramme = tab.ID;
...
}

Thank you for help !

Problem resolved !

I have replaced

<ext:TabPanel ID="tabs"  runat="server" AutoPostBack="true"    Title="TabPanel">
</ext:TabPanel>

by

<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>

And I have added this

this.PlaceHolder1.Controls.Add(tabs);

Thanks for the update.

I feel your original attempt should have worked, and I suspected there was a problem in the TabPanel's LoadPostData Method. I'm going to try and figure exactly what is going wrong.
