TabContainer server event

Hi

I try to use TabContainer control and his event OnActiveTabChanged.

I have a simple page such as

<

cc1:TabContainerID="TabContainer1"runat="server"OnActiveTabChanged="TabContainer1_ActiveTabChanged"><cc1:TabPanelID="Tab1"runat="server"><ContentTemplate>

...

</ContentTemplate></cc1:TabPanel>

</

cc1:TabContainer>

And function

protectedvoid TabContainer1_ActiveTabChanged(object sender,EventArgs e)

{

string test ="sdfds";

}

But when i click on Tab and change active tab server event not fired.

Where is a problem?

Thanks

According to the documentation, the event should fire during a postback to the server, not in response to the tab being clicked.
