Hi all,

I'm having some trouble saving values from a CheckboxList asp.net control using the usercontrolwrapper.

My usercontrol reads data from an external XML file and publishes it as a checkboxlist so the Umbraco user is able to select the data he/she wants to display on the site.

So far so good: the checkboxlist displays correctly in Umbraco, but I simply can't get it to save the selected values (which are unique IDs from the XML file) as a comma separated string. What I have so far is:

protected void Page_Load(object sender, EventArgs e)
        {
            GetData();
        }

        public void GetData()
        {
            string url = "myxmlfeed";
            XmlTextReader reader = new XmlTextReader(url);
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(reader);
            XmlNodeList cars = xmlDoc.GetElementsByTagName("car");
            List<AdminCar> carList = new List<AdminCar>();
            foreach (XmlElement element in cars)
            {
                carList.Add(new AdminCar()
                {
                    Id = element.Attributes["number"].Value,
                    Model = element.ChildNodes[1].SelectSingleNode("car_model").InnerText,
                    ModelVarient = element.ChildNodes[1].SelectSingleNode("model_variant").InnerText,
                    Name = element.ChildNodes[1].SelectSingleNode("car_manufacture").InnerText,
                    Year = element.ChildNodes[1].SelectSingleNode("model_year").InnerText,
                    FullDescription = element.Attributes["number"].Value + " - " + element.ChildNodes[1].SelectSingleNode("car_manufacture").InnerText + " " + element.ChildNodes[1].SelectSingleNode("car_model").InnerText
                });
            }

            if (carList.Count > 0)
            {
                CheckBoxList1.DataSource = carList;
                CheckBoxList1.DataTextField = "FullDescription";
                CheckBoxList1.DataValueField = "Id";
                CheckBoxList1.DataBind();
            }   
        }

        public object value
        {
            get
            {
                string result = string.Empty;
                if (!Page.IsPostBack)
                {

                    foreach (ListItem item in CheckBoxList1.Items)
                    {
                        if (item.Selected)
                        {
                            result += item.Text + ", ";
                        }
                    }
                }
                return result;
            }
            set
            {
                lblTest.Text = value.ToString();
            }
        }

Anyone got a clue about what I'm doing wrong here? :-) And as a sidequestion: by saving the IDs as a comma separated string, will I then be able to get these with umbraco.library:GetPreValues() ?

Thanks a lot in advance!

All the best,

Bo
