protected void Page_Load(object sender, EventArgs e)
{
SiteMap.SiteMapResolve += new SiteMapResolveEventHandler(SiteMap_SiteMapresolve);
}
改为
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
SiteMap.SiteMapResolve += new SiteMapResolveEventHandler(SiteMap_SiteMapresolve);
}
}
