tabstrip and pageview

I am creating tabs and page views dynamically using code in telerik. I am attaching the close button on which my tabs will be closed. I am uploading different content url for the pageviews. My question is when i am deleting a single tab the content url of other tabs are lost i.e the pageviews disappears.How can i preserve my pageviews.What code has to be written in  protected void RadMultiPage1_PageViewCreated(object sender, Telerik.Web.UI.RadMultiPageEventArgs e)
{
}
