RadTabStrip for ASP.NET AJAX Version Q3 2008 released 11/25/2008 (release history)

RadTabStrip can be used to create wizard-like interfaces.

This example shows how to build such a wizard interface using dynamic pageviews and user controls.

Each user control contains a Next button that switches to the next tab:

private void GoToNextPageView()
{
    RadMultiPage multiPage = (RadMultiPage)Page.FindControl("RadMultiPage1");
    RadPageView professionalInfoPageView = multiPage.FindPageViewByID("Professional");

    if (professionalInfoPageView == null)
    {
        professionalInfoPageView = new RadPageView();
        professionalInfoPageView.ID = "Professional";
        multiPage.PageViews.Add(professionalInfoPageView);
    }

    professionalInfoPageView.Selected = true;
}
