    Custom Data Type value not saving

    Hello,

    I have created a Custom Data Type similar to the one outlined at http://oshyn.com/_blog/Web_Content_Management/post/Custom_DataTypes_in_Umbraco/.

    I have implemented this successfuly on a property on one of my DocumentTypes and the data saves to the database. However, when I implement this on a property on a MemberType it doesn't seem to save this value, when the member is saved.

    Is there something I am missing for implementing this for use with a MemberType?

     

    <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CompanySelector.ascx.cs" Inherits="Xris.Umbraco.Web.UserControls.CompanySelector" %>
    <div>
        <asp:DropDownList ID="ddlCompanyID" runat="server" />
    </div>

     

     

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.UI;
    using System.Web.UI.WebControls;
    using Xris.Umbraco.Data;

    namespace Xris.Umbraco.Web.UserControls
    {
        public partial class CompanySelector : System.Web.UI.UserControl, umbraco.editorControls.userControlGrapper.IUsercontrolDataEditor
        {
            public string umbracoValue;
            public object value
            {
                get { return umbracoValue; }
                set { umbracoValue = value.ToString(); }
            }
            protected void Page_Init(object sender, EventArgs e)
            {
                List<MemberCompany> companies = MemberCompany.GetList().OrderBy(c => c.Name).ToList();
                ddlCompanyID.Items.Add(new ListItem("-- Select a Company --", ""));
                foreach (MemberCompany company in companies)
                {
                    ddlCompanyID.Items.Add(new ListItem(company.Name, company.CompanyID.ToString()));
                }
            }
            protected void Page_Load(object sender, EventArgs e)
            {
                if (Page.IsPostBack)
                {
                    int selectedCompanyID = Int32.TryParse(ddlCompanyID.SelectedValue, out selectedCompanyID) ? selectedCompanyID : 0;
                    if (MemberCompany.ExistsInDatabase(selectedCompanyID))
                    {
                        umbracoValue = selectedCompanyID.ToString();
                    }
                }
                LoadValue();
            }
            private void LoadValue()
            {
                if (umbracoValue != null) ddlCompanyID.SelectedValue = umbracoValue.ToString();
            }
        }
    }

    It would seem that when the DataType is being used as a property on the MemberType, the SelectedValue on ddlCompanyID is not being maintained on postback for some reason. Yet, as mentioned, it does when used on a DocumentType.

    I have managed to work arround this by obtaining the submitted value of ddlCompanyID using the Request object. I have modified the Page_Load function to the following:

    protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack)
{
        int selectedCompanyID = 0;
        if (Request[ddlCompanyID.UniqueID] != null)
        selectedCompanyID = Int32.TryParse(Request[ddlCompanyID.UniqueID].ToString(), out selectedCompanyID) ? selectedCompanyID : 0;
                
        if (MemberCompany.ExistsInDatabase(selectedCompanyID))
        umbracoValue = selectedCompanyID.ToString();
    }

    LoadValue();
}
