    Hello!

    Try this one:

    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.SelectBox1.GetStore();

            store.DataSource = new object[]
        {
            new object[] { "AL", "Alabama", "The Heart of Dixie" },
            new object[] { "AK", "Alaska", "The Land of the Midnight Sun" },
            new object[] { "AZ", "Arizona", "The Grand Canyon State" },
            new object[] { "AR", "Arkansas", "The Natural State" },
            new object[] { "CA", "California", "The Golden State" },
            new object[] { "CO", "Colorado", "The Mountain State" }
        };

            store.DataBind();
        }
    }
    
    protected void Click(object sender, DirectEventArgs e)
    {
        var l = SelectBox1.SelectedItems.Select(o => o.Value).ToList();
        X.Msg.Alert("Values", string.Join(",", SelectBox1.SelectedItems.Select(o => o.Value).ToArray())).Show();
    }
</script>
