I am attemtping to add a tabbed control to an UpdatePanel that is created during a web part's CreateChildControls function.  The intention is to have a timer scroll throught the tabs displaying content until a user selects one of the tabs.  The tab control work great when it is added to the web part controls.  When I attempt to add the tabbed control to an update panel the web part fails to load.  I can add the tabbed panel to the web part controls and I can add the update panel to the web part controls, but as soon as I try to add the tabbed control to the update panel everything goes bad.

SOURCE CODE:  

protected override void CreateChildControls()
{
  _updatePanel = new UpdatePanel();
  _tabContainer = new TabContainer();
 
  ...  //Populate a list of strings with the tab header text
 
  foreach(String s in StringList)
  {
    TabPanel tp = new TabPanel();
    tp.HeaderText = s;
    _tabContainer.Tabs.Add(tp);
 
    ...  //Populate the Tab with information
  }
 
  _updatePanel.Controls.Add(_tabContainer);
  Controls.Add(_updatePanel);
}

Try do:

_updatePanel.ContentTemplate = new CompiledTemplateBuilder(new BuildTemplateMethod(IncluirControleNoContainer));

    private void IncluirControleNoContainer(Control container)
    {
        container.Controls.Add(_controle); // Set your control in place of "_controle" field.
    }

I do that when Ajax was Atlas and it worked. I don´t tested in Ajax.

u have to add to contenttempllatecontainer like this..

UpdatePanel1.ContentTemplateContainer.Controls.Add(myControl);

You can use

UpdatePanel.ContentTemplateContainer.Controls.Add(control);
