Hi
I study one example code .. and this example written on C#

I can't understand how to translate lins to Visual Basic :))

List<object> data = new List<object>();
data.Add(new{Id=id, Name = name});

Here is full source

        protected void CitiesRefresh(object sender, StoreRefreshDataEventArgs e)
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(HttpContext.Current.Server.MapPath("Cities.xml"));
            List<object> data = new List<object>();

            foreach (XmlNode cityNode in xmlDoc.SelectNodes(string.Concat("countries/country[@code='", this.Countries.SelectedItem.Value, "']/city")))
            {
                string id = cityNode.SelectSingleNode("id").InnerText;
                string name = cityNode.SelectSingleNode("name").InnerText;

                data.Add(new{Id=id, Name = name});
            }
            this.CitiesStore.DataSource = data;

            this.CitiesStore.DataBind();
